AF93/IS903 Safety Statements 

The following safety statements relate to the 

installation, operation and troubleshooting of 

Cutler-Hammer Adjustable Frequency Drives. 

Notice - Make sure you read and understand 

the installation procedures in this manual 

before you attempt to operate or troubleshoot 

the equipment. 

Danger High Voltage 

Motor control equipment and electronic 

controllers are connected to hazardous line 

voltage. When you install or service Adjustable 

Frequency Drives and electronic controllers, 

there may be exposed components with their 

cases and protrusions at or above line potential. 

Take extreme care to protect yourself and others 

against shock: 

¥ Observe all shock hazard labels that may be 

located inside the drive. 

¥ Stand on an insulating pad and make it a 

habit to use only one hand when installing or 

checking components. 

¥ Always work with another person in case an 

emergency occurs. 

¥ Always disconnect power before you install 

or check controllers or perform maintenance. 

¥ Be sure equipment is properly grounded. 

¥ Make sure that all electrical work conforms 

with the National Electrical Codes and local 

regulations. 

¥ Installation should only be performed by 

qualified personnel.

Danger High Voltage 

Internal parts of the drive are at line voltage 

when AC power is connected to input terminals. 

This voltage is extremely dangerous and can 

cause death or serious injury. When the supply 

is disconnected from the input terminal block, it 

will take up to 10 minutes before the DC bus 

capacitors are discharged to a safe voltage. 

To ensure the voltage is safe, monitor the 

capacitor discharge with a digital voltmeter 

connected between the ÒAÓ and ÒBÓ terminals on 

the capacitor assembly as described in 

Section 5, Troubleshooting. Do not work on the 

drive until the capacitors have completely 

discharged. Do not attempt to discharge the 

capacitors by short circuiting the bus. 

Danger 

AF93/IS903 Adjustable Frequency Drives are 

not suitable for use in an explosive atmosphere 

or in a ÒHazardous (Classified) Location.Ó See 

Article 500 of the National Electric Code. 

Caution 

A hazard of potential damage to your drive, due 

to overheating, exists if your drive is operated at 

a line impedance below 1%. 

You must ensure that the input line power has 

an impedance of at least 1%, and less than or 

equal to 5% for proper drive operation. Damage 

may occur if the source impedance is less than 

1%. If the source impedance is more than 5%, 

the drive may not provide rated output voltage. 

Install a AF93/IS903 1% input line reactor if your 

line impedance measures below 1%. 

Warning 

Safety 

Carefully consider the application when you 

select AF93/IS903 Adjustable Frequency Drive 

components and options and associated drive 

motor. You must ensure that your application 

meets the restrictions stated in this manual and 

the nameplate of your drive. 

Failure to observe these restrictions can cause 

personal injury or damage to personal property 

and could void your warranty: 

¥ Make sure selected equipment meets the 

requirements of the NEC, NEMA, UL, CSA, 

IEC, IEEE, and local codes. 

¥ Pay particular attention to the requirements 

for motor and power disconnect devices, 

emergency stop pushbuttons, pre-start 

alarms and guards on mechanical power 

transmission apparatus. 

¥ Make sure motor selected is appropriately 

sized for the application. Follow the 

recommendations in Section 2 of this 

manual, Pre-Installation. 

¥ If you configure the drive to operate above 

60 Hz, the motor may operate above its 

nameplate speed. Personal injury or 

equipment damage may exist when you 

operate the motor and driven machines 

above their rated speed. Make certain that all 

guards and shields are in place before 

operating at any speed. Refer to the motor 

manufacturer to verify safe motor speed. 

Before operating the equipment, make sure 

that appropriate guards and safety devices 

are in place. 


S-3

¥ Always wear safety glasses when you 

operate rotating mechanical equipment. 

¥ Stand clear, and make sure all hands and 

feet are clear, of rotating mechanical 

equipment before you start the Adjustable 

Frequency Drive. 

¥ Refer to OSHA rules and regulations, 

paragraph 1910.219 for the use of guards on 

mechanical power transmission devices. 


S-4 

Warning 

Caution 

AF93/IS903 Adjustable Frequency Drives 

contain components and sub-assemblies that 

are sensitive to electrostatic discharge. Static 

control precautions are required when installing, 

testing, servicing, or repairing your Adjustable 

Frequency Drive. Component damage may 

result if you ignore electrostatic discharge 

control procedures. Observe the following 

precautions when you are working with electrical 

subassemblies: 

¥ Before opening the enclosure, discharge 

static electricity from your body by touching a 

grounded metal object. 

¥ When installing the equipment, connect the 

equipment ground conductor as soon as 

possible. 

¥ Keep your hands and tools away from the 

electronic circuitry as much as possible. Nonconductive 

materials such as paper, plastic 

and Styrofoam must be kept away from the 

electronic circuitry. Do not use tape in the 

equipment enclosure. Pulling tape from a roll 

generates a high static charge. 

¥ Printed circuit boards must be repaired by 

Cutler-Hammer technicians. Field service of 

printed circuit boards inside your AF93/IS903 

is not possible without the proper software or 

diagnostic tools.

Although every precaution is taken to ensure 

that the unit is delivered in good condition, take 

a moment to inspect your drive after it arrives at 

your plant: 

1. Inspect the shipping container for evidence 

of rough handling immediately after the unit 

arrives. Report all damage to the freight 

carrier and your nearest Cutler-Hammer 

customer support center and your Cutler- 

Hammer sales representative. 

2. Carefully unpack the drive, taking care to 

save the shipping container and any packing 

material should you need to return the unit at 

a later date. Verify that the items on the 

packing list or bill of lading agree with your 

order. 


2-4 

! Warning 

Large frame AF93/IS903 Adjustable Frequency 

Drives may require more than one person to 

move from one location to another. Observe 

proper lifting techniques to avoid injury when 

handling heavy electrical equipment. 

3. If you are not installing the drive right away, 

store the drive in a clean, dry, area where 

the ambient temperature is between -4 to 

158¡F (-20 to 70¡C) and less than or equal 

to 95% humidity (non condensing). 

Make sure the drive is not subject to a 

corrosive atmosphere (such as H 2 S).

Where to Locate Drive 

Consider the following: 

1. Locate the drive in an area consistent with 

the environment specifications listed in the 

Specifications section of this manual. 

Mount enclosures away from heavy and 

overhead construction. 

2. Select the type of enclosure that meets your 

application. 

Note: Standard AF93/IS903 NEMA 1 drives 

can withstand an ambient temperature of 

122¡F (50¡C) up to 3,300 feet (1000 meters) 

above sea level. Standard AF93/IS903 

NEMA 12 drives can withstand an ambient 

temperature of 104¡F (40¡C) up to 3,300 feet 

(1000 meters) above sea level. If you install 

the drive in an optional enclosure, the 

maximum temperature is derated. 

If you install an enclosure at temperatures 

exceeding these values, you must derate the 

unit as follows: 

For every 9¡F (5¡C) over the rated 

temperature you must derate the 

AF93/IS903 current ratings by 10%. 

However, do not exceed a maximum of 

131¡F (55¡C) under any circumstances. 

In addition for every 1000 feet (300 meters) 

above the rated altitude, you must derate the 

AF93/IS903 current ratings by 2%. 


INSTALLATION 

3. Refer to the illustrations in the Drawings 

section of this manual for the mounting 

dimensions of each enclosure. 

4. Make sure there is plenty of ventilating 

space surrounding the drive. Refer to the 

illustrations in the Drawings section of this 

manual for ventilation clearances. 


2-5


INSTALLATION 

Application Considerations 

When you plan your AF93/IS903 Adjustable 

Frequency Drive installation, consider its 

application. Different applications, such as 

industrial process control and HVAC system 

control, require different drive options, motors 

and software configuration. 

The following is a list of items you should keep in 

mind when you plan the installation and order 

the materials. It is important to note that some of 

the options available for your drive must be 

installed at the factory. 

AF93/IS903 Options 

1. Remember you must have an input line 

impedance of at least 1% and not over 5% 

for proper drive operation. You should 

calculate the input line impedance to 

determine whether a 1% input reactor is 

required. Refer to the discussion on Input 

Line Considerations later in this section for 

more details on determining input line 

impedance. 

2. Order a 3% or 5% input line reactor to 

correct input line harmonic distortions as 

required. Refer to the discussion on Input 

Line Characteristics on later in this section 

for more details for more details on harmonic 

distortions. 


2-6 

3. An AF93/IS903 circuit breaker is a lockable 

means for disconnecting the motor from the 

power source. The circuit breaker is 

mounted in an optional NEMA 1 or 12 

enclosure or MCC.


Motor Selection 

Careful consideration of the proper motor is 

essential to obtain optimum performance from 

your drive. Contact your Cutler-Hammer sales 

representative or distributor for additional 

assistance and/or literature regarding motor 

selection and other aspects of drive applications. 

1. Your AF93/IS903 drive is designed to be 

connected directly to a single, NEMA design 

B, three phase AC motor. The motor must be 

selected and applied so that the average 

operating motor current and horsepower do 

not exceed the continuous current and 

horsepower ratings of the drive. The 

intermittent operating current must not 

exceed the intermittent current rating of the 

drive. 

2. Consider the effect of speed on the cooling 

capacity of the motor. As you slow down 

some types of motors (such as a Totally 

Enclosed Fan Cooled [TEFC]), its internal 

fan turns slower which reduces air flow 

through the motor. Typically, these types of 

motors may overheat if you operate them for 

extended periods of time at their rated 

torque and a reduced speed (less than 50% 

of full speed). Choose a motor that matches 

the expected duty, torque range and speed. 


INSTALLATION 

3. Multiple motors may be operated by an 

AF93/IS903 drive if: 

¥ Total current from all motors does not 

exceed the current rating of the AF93/IS903. 

¥ Individual motor overload protection is 

supplied. 

¥ All motors must start and change speed 

together. 

! Warning 

If you configure the drive to operate above 60 

Hz, the motor may operate above its nameplate 

speed. Personal injury or equipment damage 

may exist when you operate the motor and 

driven machines above their rated speed. Make 

certain that all guards and shields are in place 

before operating at any speed. Refer to the 

motor manufacturer to verify safe motor speed. 


2-7


INSTALLATION 

Input Line Considerations 

All wiring must comply with the requirements of 

the National Electric Code (NEC) and/or other 

codes as required by the authority having 

jurisdiction over the installation. The installer 

must ensure that the electrical connections at 

the site conform with the connection diagrams 

shipped with the drive. 

Note: Make sure you use the most recent 

version of the codes when you install 

your AF93/IS903 drive. 

Input Line Conductor and Branch Circuit 

Overload Protection Selection 

Use a combination of the following guidelines to 

choose the correct input line conductors and 

proper branch circuit overload protection: 

Note: Select the input line conductor size and 

branch circuit overload protection in 

accordance with applicable code 

requirements. 

¥ The input line and branch circuit overload 

protection must be rated for the input voltage 

and current stated on the nameplate of the 

drive. 

¥ For runs over 300 feet, consider the 

recommended minimum wire size listed in 

Table 2-1. 

¥ In addition, consider the wire size capacity of 

the input line terminals: 

2 to 10 Hp Maximum wire size is #10 AWG 


¥ The input line conductors must be made of 

copper with a temperature rating of at least 

167¡F (75¡C). 

¥ The power terminal tightening torque range 

is 16-18 in. lbs. on terminals L1, L2, L3, T1, 

T2, T3, and the ground lugs. 


2-8 

Grounding Connections 

For personal safety and reliable equipment 

operation, firmly connect each chassis to earth 

ground as shown in the connection diagrams in 

the Drawings section of this manual. 

The AF93/IS903 chassis ground conductor 

should be the same size as the input line 

conductors or sized according to electrical code 

requirements. Use a copper or aluminum 

conductor. 

Connection to a grounded conduit does not 

provide an adequate equipment ground. 

Make sure that all operatorÕs control stations and 

motor frames are adequately grounded. 

Input Line Impedance 

You must ensure that the input line power 

has an impedance of at least 1% and less 

than or equal to 5% equated to drive size for 

proper operation. Damage to the drive may 

occur if the source impedance is less than 

1%. If the source impedance is more than 

5%, the drive may not provide rated output 

voltage. 

Actual input current varies considerably in 

response to the efficiency and power factor of 

the motor connected to your drive and the 

impedance of the power source. 

Since power source impedance has an effect on 

the harmonic content of the input current, the 

amount of impedance affects the value of the 

input line current.


The value of source impedance is expressed as 

a percent of the effective impedance of the 

drive. 

To determine the source impedance as a 

percent of the effective impedance of the drive, 

you must know: 

¥ The short circuit capacity of the power 

source at the driveÕs input power terminals. 

¥ The full load (output) current rating of the 

drive (found on the nameplate). 

The following calculation provides the source 

impedance as a percent of the effective 

impedance of the drive: 

Full Load Current 

Short Circuit Capacity 

* 100 

= Source 

Impedance 


INSTALLATION 

The short circuit capacity must be at least 20 

times the full load current rating (5% 

impedance) and no more than 100 times the full 

load current rating (1% impedance). 

For example, if the full load (output) current of 

an AF93/IS903 drive is 22 amps and the short 

circuit current capacity of the power source is 

2200 amps, the source impedance is: 

22 

2200 

* = 1.00% 

100 

Since the design of a power distribution system 

often includes a short circuit capacity study, 

power distribution system drawings or other 

distribution system documentation may show 

the short circuit capacity at various points. If this 

data is not available, contact your Cutler- 

Hammer sales representative or distributor for 

help on estimating or calculating short circuit 

current capacity.

Harmonic Distortion 

As stated in the discussion on Input Line 

Impedance, source impedance can affect the 

harmonic content of the input line current. As 

source impedance increases, line current 

harmonic content decreases. 

The relationship between input line impedance 

and harmonic voltage distortion is just the 

opposite of the relationship between impedance 

and current distortion. As source impedance 

increases, so does harmonic voltage distortion. 


INSTALLATION 

For example, if the source impedance 

(expressed as a percent of the effective 

impedance of the drive) is 1%, you will cause 

less than 5% harmonic voltage distortion when 

you connect a single AF93/IS903 to an 

undistorted power source. If the source 

impedance increases to 5%, the resulting 

harmonic distortion is less than 10%. 

Contact your Cutler-Hammer sales 

representative or distributor for assistance in 

estimating harmonic distortion in multiple drive 

installations. They can also provide assistance in 

selecting a means of harmonic reduction such 

as line reactors. 


2-11


INSTALLATION 


Input Line Routing 

For 7.5 to 25 Hp AF93/IS903: 

¥ If you use conduit - Use a separate 

conduit for input line conductors and output 

power conductors. Never route analog and 

digital wiring from any equipment in the 

same conduit as input or output power 

wiring. 

¥ If you use cable trays - Use a separate 

cable tray for input line conductors and 

output line conductors. Never route analog 

and digital wiring from any equipment in 

the same cable tray as input or output 

power wiring. 

For 2 to 5 Hp AF93/IS903: 

If you use conduit, use separate conduit for 

input and output power and AF93/IS903 control 

wiring, up to the AF93/IS903 drive. At the drive 

use a T-coupling to combine the input power and 

output power wiring and attach to conduit entry 

point. 

Multiple Conductor Wiring 

If multiconductor wiring is used, a separate 

multiconductor cable must be used for the input 

line wiring for each drive. 

Line Fuses 

Line fuses are intended to remove input line 

voltage from the drive in the event of internal 

component and drive failure. Line fuses must 

not be used in place of branch circuit 

overload protection. 

CT (Current Transformer) 

On 2 Hp, 3 Hp, and 5 Hp units manufactured 

prior to May 2, 1996 and 7.5 and 10 Hp units 

manufactured prior to July 1, 1996, a CT was 

supplied internal to the drive for ground fault 

protection. On units manufactured after these 

dates, the ground fault protection is built into the 

transistor module. If your drive contains a CT to 

provide ground fault protection, input lines L1, 


2-12 

L2, and L3 must pass through the CT when you 

are installing the input lines (See 5 and 10 Hp 

connection drawings): 

1. Remove the foam packing. 

2. Pass L1, L2, and L3 through the knockout 

and current transformer and then connect 

them to terminals L1, L2, and L3, 

respectively. 

3. DO NOT pass any ground lines through the 

current transformer. 

4. The current transformer is connected to the 

logic board at the factory. 

AF93/IS903 Circuit Breaker 

This option is used as a mechanical means of 

disconnecting output power to the motor. 

AF93/IS903 circuit breakers must not be used 

in place of branch circuit overload 

protection. 

Isolation Transformers 

Isolation transformers can be used with 

AF93/IS903 Adjustable Frequency Drives. 

Remember that the input line impedance must 

be at least 1% and not over 5% with the drive 

running. See the previous discussion on Input 

Line Impedance. 

Power Factor Correction 

The displacement power factor at the input 

terminals of an AF93/IS903 drive is 

approximately 0.95 at all operating speeds and 

loads. Therefore, power factor correction 

capacitors are not required and should not be 

installed. If capacitors for correcting the power 

factor of other equipment are installed too close 

to the drive, there may be an undesirable 

interaction between the capacitors and the drive. 

Standby Power Generation 

Three phase standby power generators can be 

used with AF93/IS903 Adjustable Frequency 

Drives as long as the input line impedance is 

within the 1% to 5% range.

Output Power Considerations 

To comply with local and nationally recognized 

codes, such as the NEC, you must consider 

proper output power wiring when you plan your 

Adjustable Frequency Drive installation. 




Output Power Conductor and Ground 

Conductor Sizing 

Use a combination of the following guidelines to 

choose the correct output line conductors and 

proper branch circuit overload protection: 

Note: Select the output power conductor size in 

accordance with applicable code 

requirements. 

¥ The output power conductors must be rated 

for the output voltage and current stated on 

the nameplate of the drive. 

¥ For runs over 300 feet, consider the 

recommended minimum wire size listed in 

Table 2-1. 

¥ In addition, consider the wire size capacity of 

the output line terminals: 



¥ The input line conductors must be made of 

copper with a temperature rating of at least 

167¡F (75¡C). 

¥ The power terminal tightening torque range 

is 16-18 in. lbs. on terminals L1, L2, L3, T1, 

T2, T3, and the ground lugs. 

¥ The AF93/IS903 chassis ground conductor 

should be the same size as the output line 

conductors or sized according to electrical 

code requirements. Use a copper or 

aluminum conductor. 

¥ Connection to a grounded conduit does not 

provide an adequate equipment ground. 

¥ Make sure that all operatorÕs control stations 

and motor frames are adequately grounded. 


INSTALLATION 

Output Power Conductor Routing 

For 7.5 to 25 Hp AF93/IS903: 

¥ If you use conduit - Use a separate conduit 

for input line conductors and output power 

conductors. Never route analog and digital 

wiring from any equipment in the same 

conduit as input or output power wiring. 

¥ If you use cable trays - Use a separate 

cable tray for input line conductors and 

output line conductors. Never route analog 

and digital wiring from any equipment in 

the same cable tray as input or output 

power wiring. 







point. 

Overcurrent Protection 

AF93/IS903 Adjustable Frequency Drives are 

designed to automatically provide overcurrent 

protection for the output power circuit only if one 

motor is connected to the drive and sized to 

match the drive. 

If more than one motor is connected to the drive, 

each motor must have its own overcurrent 

protection. In addition, the combined input 

current rating on the nameplate of each motor 

must not exceed the output current rating of the 

drive. 

Power Factor Correction 

Power factor correction capacitors must never 

be connected to the output of the drive. They 

may damage the drive and would not serve any 

useful purpose. 


2-13


INSTALLATION 

Analog and Digital Signal Considerations 

To comply with the design of the drive and local 

and nationally recognized codes, consider proper 

analog and digital signal wiring when you plan 

your Adjustable Frequency Drive installation. 




External Fault Signal 

Some configurations, such as an optional 

overload interlock relay, provide an external fault 

signal to the drive so the drive will not start if the 

relay has tripped and has not been reset. If this 

or other option that requires an external fault 

signal is installed by the factory, the signal is 

factory wired. See the connection diagrams in 

the Drawings section of this manual for details. 

Analog and Digital Signal Wiring 

¥ 18 AWG wire size is recommended. 

Minimum wire size is 20 AWG. Maximum 

wire size is 16 AWG. 

¥ One conductor per terminal for 16 AWG 

conductors. Two conductors per terminal at 

18 AWG. Three conductors per terminal at 

20 AWG. 

¥ Maximum length is 500 feet; call your Cutler- 

Hammer sales representative or distributor 

for longer runs. 

¥ Use shielded cable for the analog signal 

conductors where indicated on the terminal 

block connection diagram. Typically, 

shielding is required for all analog input and 

output runs. 

All digital signal runs over 75 feet long 

should be shielded. 

¥ Only ground the shield conductor of shielded 

cable at the terminal block of the drive for 

input signals only. Output signals should not 

be grounded at the drive end of the cable but 

should be grounded at the device. 

AF93/IS903 Instruction 

2-14 

¥ The analog and digital signal conductors 

must be made of copper with a temperature 

rating of at least 167¡F (75¡C). 

Analog and Digital Conductor Routing 

For 7.5 to 25 Hp AF93/IS903: 

¥ If you use conduit: 

Never route analog and digital wiring 

from any equipment in the same conduit 

as input or output power wiring. 

Do not run AF93/IS903 Adjustable 

Frequency Drive analog and digital signal 

conductors in the same conduit that has 

control wiring for other equipment. 







point. 

¥ If you use cable trays: 

Never route analog and digital wiring 

from any equipment in the same cable 

tray as input or output power wiring. 

Separate analog and digital wiring for your 

AF93/IS903 drive from other control 

equipment wiring using a metal tray divider 

or keeping the conductors at least 2 inches 

apart. 

Trays containing analog and digital wiring 

should be separated from trays containing 

low voltage (up to 30 volts) power wiring by 

at least 9 inches. 

Trays containing analog and digital wiring 

should be separated from trays containing 

medium voltage (between 30 and 150 volts) 

power wiring by at least 18 inches.

Terminal Block 

The AF93/IS903 terminal block description is summarized in table 2-2 below: 

Terminal Name Terminal Description 


INSTALLATION 

1 LOOP Analog input speed reference from a 4-20mA current loop. Zin²250½. If SPEED FOLLOWER, PI REGULATOR, or ANALOG 

LOAD LIM (parameter 21) is enabled: Then if Iloop1 mA, terminal 3 is ignored and speed reference is taken from this input. Active in REMOTE mode only. 

2 AGND Analog signal common and shield tie point. 

3 POT WPR 0-10V Analog input speed command. May be attached to the wiper of a potentiometer or the output of a remote control circuit. 

Zin > 100 k½. Active if SPEED FOLLOWER, PI REGULATOR, or ANALOG LOAD LIM (parameter 23) is enabled. 

4 POT HI Analog input reference for external potentiometer. Requires a remote potentiometer of 1 k½ or greater. 

5 AOUT1 Programmable analog output 1. 0-10V signal represents 0 to full scale of the selected parameter. 

6 AOUT2 Programmable analog output 2. 0-10V signal represents 0 to full scale of the selected parameter. 

7 DIGCOM Digital Input Common. This is local digital ground. 

8 STOP Digital Input Stop/Run Enable Command. Must be LO (or connected to terminal 7) for drive to start or run; acts as a Run 

Enable. Momentary HI (or opening) stops the drive. Active in both KEYPAD and REMOTE modes. To run the drive in KEYPAD 

mode, a customer supplied jumper must be placed between terminals 7 and 8, and terminals 7 and 15. Attempting to start 

in KEYPAD mode without the jumper installation will yield a RUN DISABLED message. If drive is in AUTO RESTART mode, LO- 

HI (closed-open) transition exits the auto restart sequence and enters STOP mode without asserting a fault. If drive is in FAULT 

mode, LO- HI (closed-open) transition resets the fault and stops the drive. 

9 START Digital Start Input. In 3-wire control, a momentary contact between terminals 9 and 7 sends a RUN command to the drive. In 

2-wire control, a jumper is installed between terminals 9 and 7. Active when REMOTE mode is enabled. If drive is in AUTO 

RESTART mode, START is ignored. If drive is in FAULT mode, HI-LO (open-closed) transition while Run Enable is true resets 

the fault and starts the drive. 

10 FWD/REV Digital Fwd/Rev Input. HI (open) = Forward (clockwise rotation viewed from the motor shaft end); LO (closed to terminal 7) 

= Reverse (counter-clockwise rotation viewed from the motor shaft end). Active when REMOTE mode is enabled. 

11 ACC2/JOG Digital Accel/Decel2 Input / Jog Input. LO (closed to terminal 7) and RUN enable present (terminal 7 closed to terminal 8) selects 

second set of Accel/Decel presets in ACCEL2 mode; LO (closed to terminal 7) and RUN enable is present causes a jog motion in 

JOG mode. Active when REMOTE mode is selected. 

12 PRST1 Digital Preset Speed Input 1. Least Significant Bit (LSB) of a 3-bit binary coded speed preset select. HI (open) = 0 (OFF), 

LO (closed to terminal 7) =1 (ON). Active when REMOTE mode is selected. 

13 PRST2 Digital Preset Speed Input 2. Binary number selects one of seven internal presets entered from the setup menu. Code 0 (all 

inputs HI (open), OFF)) directs speed pot. or 4-20 mA current loop speed setting as command input. Active when REMOTE 

mode is selected. 

14 PRST3 Digital Preset Speed Input 3. MSB of a 3-bit binary coded speed preset select. Active when REMOTE mode is selected. 

15 EXTFLT Digital External Fault Trip Input. HI (opened to terminal 7) triggers an External Fault event and places the drive in FAULT mode, 

shutting it down. To run the drive in KEYPAD mode, customer supplied jumpers must be placed between terminals 7 and 

8 and terminals 7 and 15. Always active in both KEYPAD and REMOTE modes. Drive will coast to a stop.

SECTION 3 

The function for each keypad button and indicator is described on this page. The sections listed in 

italics have the detailed procedures for using the features of your keypad. The item numbers in 

parenthesis refer to the illustration of the keypad on the next page. 

Run Indicator (item 1) - This green indicator is 

on steady while running, accelerating, or 

decelerating due to a speed reference change. 

This indicator is flashing while the drive is 

searching for the motor speed during Start Into 

Spinning Motor, while waiting to accelerate during 

flux build-up of the motor, during deceleration due 

to a Stop command, while waiting to auto-restart 

during power-up or after a trip, and while DC 

braking. This applies whether the motor is running 

as a result of a Start or Jog command. 

Fault Indicator (item 2) - This red indicator is lit 

(and the Run indicator goes out) if your drive is in 

the FAULT mode. See the Troubleshooting Your 

Drive section of this manual for the procedure on 

listing fault messages on your keypad display. 

Forward Indicator (item 3) - This yellow indicator 

is on steady when the drive is operating in a 

forward direction or a Forward command is 

present and the drive is stopped. This indicator is 

flashing when a Forward command is present and 

the drive is operating in a reverse direction. 

Reverse Indicator (item 4) - This yellow indicator 

is on steady when the drive is operating in a 

reverse direction or a Reverse command is 

present and the drive is stopped. This indicator is 

flashing when a Reverse command is present and 

the drive is operating in a forward direction.

Keypad Tips and Modes 

SECTION 3 

Tips on Using Your Keypad 

Keep the following points in mind when you use the keypad: 

¥ If you press more than one button at a time, the drive will not 

respond. 

¥ In most cases, the keypad issues a command when you press 

a button, and the command stays active when you release it. 

When you press the button, hold it down for a moment before 

you release it so the drive has time to respond to the 

command. 

¥ Two minutes after you issue the last command from the 

keypad, the LCD will return to the OPERATE mode. 

¥ If the Fault indicator comes on, refer to the Troubleshooting 

Your Drive section for the procedure for displaying a fault 

message on your LCD. 

Operate, Scroll, and Change Settings Modes 

The AF93/IS903 drive has three keypad conditions: OPERATE, 

SCROLL, and CHANGE SETTINGS. 

In the OPERATE mode, the LCD displays two Operation Display 

Parameters showing current information on items such as Speed 

and Load. Use the ÒUpper DisplayÓ and ÒLower DisplayÓ 

parameters to select which Operation Display Parameters appear 

during the OPERATE mode (see Section 4, Using the 

Parameters, for more information). 

In the SCROLL mode, the Up and Down buttons scroll through 

the parameters displayed on the LCD. 

In the CHANGE SETTINGS mode, the parameter values 

described in Section 4, Using the Parameters, can be changed.

Using the Forward/Reverse Button 

SECTION 3 

Issuing a Forward Command From Your Keypad 

When the Reverse indicator is lit, pressing the F/R 

(Forward/Reverse) button sends a Forward 

command to the drive and turns On the Forward 

indicator (the Reverse indicator goes out). 

The Forward indicator will flash while the drive is 

running in the reverse direction and will continue to 

flash until the drive reaches zero speed. The 

Forward indicator will be lit steady when the drive 

begins running in the forward direction and will 

remain steady as long as both the commanded 

direction and drive direction are Forward. 

You can issue a Forward command at any time the 

drive is in KEYPAD mode. If the drive is running in 

reverse, it causes the drive to change direction. If 

the drive is stopped, the drive turns in a forward 

direction the next time you issue a Start command. 

This operation can be disabled via a software 

parameter (see Section 4, Using the Parameters, 

for more information). 

The F/R command should not be used to 

permanently reverse motor direction. To change 

motor direction, disconnect power and reverse any 

two motor leads. 

Step 1. With the Reverse indicator lit, press the 

F/R (Forward/Reverse) button.

AF93/IS903 Parameter List 

USING THE PARAMETERS 

AF93/IS903 Parameter List Legend 

Parameter Number 

Each parameter is numbered and the list 

presents the parameters in the same order they 

are displayed when you scroll them on the LCD 

(using the Up or Down buttons in the SCROLL 

mode). Indexing by parameter number makes it 

easy to find information on each parameter as 

you use your AF93/IS903 drive. 

Parameter 

(LCD Display) 

This column provides the full description of each 

parameter and its LCD display (mnemonic). 

The LCD Display appears within the parenthesis 

below each parameter name. This display 

appears on the upper line of the LCD when you 

are in the SETUP mode and are changing the 

parameter settings. The current setting of the 

parameter appears on the lower line of the LCD. 

Range of Adjustment 

This column provides the range of values you 

can choose from when you change the setting of 

a parameter. 

When the drive is in the CHANGE SETTINGS 

mode, use the Up or Down buttons to change 

the parameter data (numeric and alpha data) that 

appears on the lower line of the LCD. 

Some of the ranges depend upon the value you 

have set for another parameter. For example, the 

range of SPEED SETPOINT is ÒMinimum Speed 

to Maximum Speed.Ó This means that the range 

for this parameter starts at the value of MINIMUM 

SPEED and extends to the value of MAXIMUM 

SPEED. 

Note that instead of an analog value, some of the 

parameters, such as digital and analog outputs, 

provide a list of functions or conditions on the 

lower line of the LCD to choose from. These are 

noted with quotation marks (Ò Ó) in the Range of 

Adjustment column. 

When you set the value for a digital or analog 

output parameter, you choose the condition that 

will cause the relay contact to close (for 

RELAY 1 or 2) or for the analog voltage to be 

output (ANALOG OUTPUT #1 or #2). 

Notes 


4-2 

This column provides specific information about 

using the parameter. 

Note that many parameters list Run Locked in 

this column. This means that you cannot change 

the settings for this parameter while the RUN 

indicator is lit. 

Factory Setting 

This is the value set at the factory for the 

parameter.

Run Locked?: No 

Factory Setting: ÒSPEEDÓ 

This parameter allows you to select the 

Operation Display Parameters you want to 

appear on the upper line of the driveÕs LCD when 

the drive is in the OPERATE mode. Elapsed time 

resets to 0 when 6553.5 hours are exceeded.

(0-6553.5 hours). Units 

are shown in the 

parenthesis. 


Factory Setting: ÒLOADÓ 

This parameter allows you to select the 

Operation Display Parameters you want to 

appear on the lower line of the driveÕs LCD when 

the drive is in the OPERATE mode. Elapsed time 

resets to 0 when 6553.5 hours are exceeded. 




Mnemonic: SPEED SETPOINT 

Range of Adjustment: Between Minimum Speed 

and Maximum Speed 


Factory Setting: 0 

This parameter defines the speed setpoint used 

only in the KEYPAD mode. This is the only way 

to change speed setpoint in the KEYPAD mode. 

Note that Speed Setpoint is ignored if the drive is 

REMOTE mode. When drive is in RUN and 

KEYPAD modes and you press the Up or Down 

button, drive goes directly to the Speed Setpoint 

parameter. Pressing the Up or Down button 

additional times will change the current value of 

the Speed Setpoint parameter. 

Minimum Speed 



Mnemonic: MIN SPEED 

Range of Adjustment: 25 to 10800 RPM 


Factory Setting: 50 RPM 

This parameter defines the minimum speed limit 

at which the drive will be allowed to operate. 

Minimum speed must be set lower than 

maximum speed. 

Maximum Speed 



Mnemonic: MAX SPEED 



Factory Setting: 1800 RPM 

This parameter defines the maximum speed limit 

at which the drive will be allowed to operate. If 

the drive reaches the Load Limit (parameter 22) 

or ÒANALOG LOAD LIMÓ (parameter 23) and you 

are ramping up to the maximum speed, the drive 

will go into foldback and stay at the speed where 

the load limit was reached.

Minimum Potentiometer 

Reference 



Mnemonic: MIN POT REF 

Range of Adjustment: 0 to 100% 

Run Locked?: Yes 

Factory Setting: 10% 

Minimum and maximum analog potentiometer 

values are used to scale potentiometer inputs 

(setpoint and feedback) if the drive is in the 

REMOTE mode. See Remote Function 

(parameter 23) for details. Minimum 

Potentiometer Reference defines the minimum 

value in terms of percent of full range. If the full 

range is used, the following are the values for 

direct and inverse acting control: 

0% equals min. speed at 0V (direct acting) 

100% equals min. speed at 10V (inverse acting) 

Maximum Potentiometer 

Reference 



Mnemonic: MAX POT REF 




This parameter defines the maximum value in 

terms of percent of full range. If the full range is 

used, the following are the values for direct and 

inverse acting control: 

100% equals max. speed at 10V (direct acting) 

0% equals max. speed at 0V (inverse acting) 


4-14 

Minimum Analog Reference 



Mnemonic: MIN ANALOG REF 




Minimum and maximum analog reference values 

are used to scale analog inputs (setpoint and 

feedback) if the drive is in the REMOTE mode. 

See Remote Function (parameter 23) for details. 

Minimum Analog Reference defines the minimum 

value in terms of percent of full range. If the full 

range is used, the following are the values for 

direct and inverse acting control: 

0% equals min. speed at 4 mA (direct acting) 

100% equals min. speed at 20 mA (inverse acting) 

Maximum Analog 

Reference 



Mnemonic: MAX ANALOG REF 




This parameter defines the maximum value in 

terms of percent of full range. If the full range is 

used, the following are the values for direct and 

inverse acting control: 

100% equals max. speed at 20 mA (direct 

acting) 

0% equals max. speed at 4 mA (inverse acting)






Mnemonic: ACCEL/DECEL MODE 

Range of Adjustment: ÒLINEARÓ or ÒS-CURVEÓ 


Factory Setting: ÒLINEARÓ 

This parameter defines the drives acceleration 

and deceleration profiles. Linear acceleration, as 

shown in the straight line graph, works well in 

situations where the friction and work load are 

constant. S-curve acceleration, shown in the 

second graph, works well in situations where 

there is a high breakaway torque requirement. In 

situations like conveyor belts, where a sudden 

application of force may make items tip over, 

selecting an S-curve acceleration will minimize 

jerky starts. 

The deceleration profiles would be mirror images 

of the graphs shown.

Accel Time 



Mnemonic: ACCEL TIME 

Range of Adjustment: 0.1 to 999 sec 


Factory Setting: 5 sec 

This parameter defines the time it takes the drive to 

go from zero to Maximum Speed. The drive will not 

exceed the load limit to meet this acceleration time. 

Decel Time 



Mnemonic: DECEL TIME 




This parameter defines the time it takes the drive to 

go from Maximum Speed to zero. On high inertia, 

low friction applications, the drive may decelerate in 

a greater length of time unless a braking resistor is 

present. 

Accel/Decel 2 or Jog 



Mnemonic: ACCEL2 OR JOG 

Range of Adjustment: ÒACCEL/DECEL 2Ó or 

ÒJOGÓ 


Factory Setting: ÒJOGÓ 

This parameter defines whether the drive will have 

a secondary acceleration/deceleration time (Accel 

Time 2 and Decel Time 2) or implement the jog 

speed function (Jog Speed) when terminal 11 is 

connected to terminal 7 while the drive is in the 

REMOTE mode. 


4-16 

If ÒACCEL/DECEL 2Ó is chosen, the drive is in 

REMOTE mode, and terminal 11 is connected to 

terminal 7, Accel Time (parameter 11) and Decel 

Time (parameter 12) are ignored. The drive will 

use Accel Time 2 (parameter 14) and Decel Time 

2 (parameter 15) instead. Note that both the 

acceleration and deceleration times are affected. 

If ÒJOGÓ is selected, whenever terminal 11 is 

connected to terminal 7 and RUN enable is 

present (terminal 8 connected to terminal 7), the 

drive goes into JOG mode at the speed set by 

Jog Speed (parameter 33). Note that Jog 

overrides the speed setpoint established by 

ÒSPEED FOLLOWERÓ, ÒPI REGULATORÓ, and 

Preset Speed x (parameters 26 to 32). See 

Remote Function, Priority Interaction in REMOTE 

Mode, for more information. 

Accel Time 2 



Mnemonic: ACCEL TIME 2 




If ÒACCEL/DECEL 2Ó is chosen, the drive is in 

REMOTE mode, and terminal 11 is connected to 

terminal 7, this parameter defines the time it 

takes the drive to go from zero to Maximum 

Speed. 

Decel Time 2 



Mnemonic: DECEL TIME 2 




If ÒACCEL/DECEL 2Ó (parameter 13) is chosen, 

the drive is in REMOTE mode, and terminal 11 is 

connected to terminal 7, this parameter defines 

the time it takes the drive to go from Maximum 

Speed to zero.



Motor Nameplate 

Parameters 

The values for the following six parameters (HP 

Rating, Rated Amps, Rated Efficiency, Rated 

Frequency, Rated Speed, and Rated Volts) 

should be compared to the motor nameplate after 

you install the drive. If the motor nameplate 

parameters differ from the information you must 

enter the correct setting. These values are 

essential for your drive to operate correctly.

Load Limit 



Mnemonic: LOAD LIMIT 

Range of Adjustment: 0 to 200% (2 to 10 Hp) or 

0 to 180% (15 to 25 Hp) of 

rated load, based on calculated 

motor torque rating. 


Factory Setting: 150% on constant torque 

and 110% on variable 

torque rated drives. 

This parameter sets the load limit for the drive, 

unless it is overridden by ÒANALOG LOAD LIMÓ 

(parameter 23). If the drive reaches the Load 

Limit (parameter 22) and you are ramping up to 

the Maximum Speed (parameter 5), the drive will 

go into foldback and stay at the speed where the 

load limit was reached. If the load limit control 

does not prevent an overload, the drive will shut 

down. 


4-17






Mnemonic: REMOTE FUNCTION 

Range of Adjustment: ÒSPEED FOLLOWERÓ or 

ÒPI REGULATORÓ or 

ÒANALOG LOAD LIMÓ or 

ÒDIGITAL POTÓ 


Factory Setting: ÒSPEED FOLLOWERÓ 

When your drive is in REMOTE mode, speed is 

controlled by one of the these Remote Functions: 

ÒSPEED FOLLOWERÓ, ÒPI REGULATORÓ, 

ÒANALOG LOAD LIMÓ or ÒDIGITAL POTÓ. 

A discussion about the priority interaction among 

the various signals that can control the motor 

speed follows the discussion of each type of 

remote function. 

ÒSPEED FOLLOWERÓ - You can vary the speed 

setpoint using a current or voltage speed follower 

input. The speed follower input can be connected 

as follows: 

¥ If the signal is 4-20 mA, connect it to 

terminals 1 and 2. 

¥ If the signal is 0-10 VDC, connect it to 


¥ If the signal comes from a potentiometer, 

connect it to terminals 2, 3, and 4. 

¥ If the signal is 0-5 VDC, and the output 

impedance of the signal follower is less than 

or equal to 250 ½ and can output 20 mA, 

connect the signal to terminals 1 and 2. 

ÒPI REGULATORÓ - You can automatically 

maintain a reference setpoint using the ÒPI 

REGULATORÓ option. This option incorporates a 

feedback signal and reference setpoint. The 

following connections are required: 

Setpoint - 0-10 VDC, connect it to terminals 2 

and 3 (terminal 3 is +) or connect potentiometer 

to terminals 2, 3, and 4. 


4-18 

Feedback - 4-20 mA connected to terminals 1 

and 2. A 0-5 VDC signal can also be connected 

to these terminals if the output impedance of the 

transducer is less than or equal to 250 ½ and it 

can output 20 mA. 

PI Regulator Feedback - The feedback signal is 

calibrated to provide constant information on 

whether the motor is actually running faster or 

slower than the setpoint. If the motor is running 

faster than setpoint, the drive reduces the 

frequency and if the motor is running slower than 

setpoint, the drive increases the frequency. 

Integral and Proportional Gain - In simple 

terms, the Integral Gain parameter controls how 

quickly the drive responds to information 

provided by the feedback signal and the 

Proportional Gain parameter controls how close 

to the target value the system will maintain 

control. It takes some trial and error in setting 

these parameters since some applications have 

a natural tendency to favor tight control and 

others may start to quickly oscillate around the 

target speed the tighter you try to maintain 

control. 

PI Regulator Application Example - PI is a 

closed loop control system consisting of a set 

point, a process variable, and an error signal 

which will control the drive output. Typical 

applications include wet well level control, 

temperature or pressure control, or flow rate 

control. 

PI control starts with a PI Setpoint adjusted by a 

remote signal input, such as a potentiometer. The 

drive compares the setpoint to a process variable 

signal, PI Feedback, and creates an error signal. 

The error signal is processed to create the speed 

reference for the drive. 

In the example shown in Figure 4-1, a pressure 

transducer provides a 4-20 mA signal that 

corresponds to the duct pressure. The drive will 

control the speed of the blower to maintain the 

desired duct pressure regardless of the amount of 

air flow being supplied through the duct.



Remote Function (Cont.) 

Since the PI Regulator software works best when 

the analog feedback is scaled to the full range, we 

recommend that the Minimum Analog Reference 

(parameter 8) be set to 0% and the Maximum 

Analog Reference (parameter 9) be set to 100% 

(for direct acting control). In applications that 

require inverse control, set the Minimum Analog 

Reference parameter to 100% and the Maximum 

Analog Reference parameter to 0%. 

Using ÒMIN POT REFÓ and ÒMAX POT REFÓ, the 

operating band can be adjusted for the specific 

application. In this example for a desired setpoint 

of 10 psi and a maximum range of 8 to 12 psi, the 

operator would set Minimum Potentiometer 

Reference and Maximum Potentiometer 

Reference to the equivalent percentages of these 

values.

Controller 

AF93/IS903 

We recommend that, for most applications, you 

set the initial value of the Integral Gain (parameter 

24) to 10000 and Proportional Gain (parameter 

25) to 10000. Since these values are not Run 

Locked (can be changed while the system is 

running) you can adjust them (in 1000 unit 

intervals) while you observe its operation. To 

increase or decrease the response time to 

changes in feedback value, you might want to 

change the value of Integral Gain. To control the 

amount of under and overshoot, you might want to 

adjust the Proportional Gain. Note that some types 

of systems, such as HVAC control, might not need 

much proportional gain.

Remote Function (Cont.) 

ÒANALOG LOAD LIMÓ - This function combines 

a speed follower with an external method of 

controlling the load limit: 

Speed Follower - 4-20 mA connected to terminals 

1 and 2. A 0-5 VDC signal can also be connected 

to these terminals if the output impedance of the 

transducer is less than or equal to 250 ½ and it 

can output 20 mA. 

Load Limit Control - 0-10 VDC, connect it to 

terminals 2 and 3. Connect potentiometer to 

terminals 2, 3, and 4. 

This function allows you to control the load limit 

and speed from a remote station in situations 

where you expect wide variations in the load. 

Note that ÒANALOG LOAD LIMÓ is capped by 

ÒLOAD LIMITÓ (parameter 22). 

Remember, when the load limit you set is 

exceeded, the drive will go into foldback and 

reduce speed to try to prevent further overload. 

The lower you set the load limit, the lower the 

speed will be when the drive goes into foldback. 

If the load limit control does not prevent an 

overload, the drive will shut down. 

ÒDIGITAL POTÓ - This function sets up a 

ÒpotentiometerÓ that allows you to smoothly 

increase or decrease motor speed at a remote 

station. 

If you connect terminals 13 and 7, the speed 

increases at the rate established by Accel Time 

(parameter 11) or Accel Time 2 (parameter 14). 

When you disconnect terminal 13 from 7, the 

speed stops increasing and remains constant 

(drive ignores terminal 11, Jog). 

If you connect terminals 14 and 7, the speed 

decreases at the rate established by Decel Time 

(parameter 12) or Decel Time 2 (parameter 15). 

When you disconnect terminal 14 from 7, the 

speed stops decreasing and remains constant 

(drive ignores terminal 11, Jog). 

If both 13 and 14 are connected to 7 the speed 

decreases at a rate established by the 

appropriate deceleration time. 


4-20 

The POT WPR (terminal 3) is used to set the 

load limit while in DIGITAL POT mode. If a load 

limit control potentiometer is not used to control 

torque, a jumper must be installed between 


Priority Interaction in REMOTE Mode 

There is a priority scheme that the drive uses to 

establish the speed setpoint in the REMOTE 

mode: 

Priority 1 (Lowest Priority) - 0-10 VDC Speed 

Follower 

Priority 2 - 4-20 mA Speed Follower (If Signal 

exceeds 1 mA) 

Priority 3 - PI Regulator 

Priority 4 - Terminals 12, 13, or 14 closed to 

terminal 7 (Preset Speeds or Digital 

Potentiometer) 

¥ If you use SPEED FOLLOWER, a current 

source greater than 1 mA will override a 

voltage source. 

¥ If you use SPEED FOLLOWER, a voltage 

source will override a current source less 

than 1 mA. 

¥ If you connect terminal 12, 13, or 14 to 

terminal 7, Preset Speeds will override 

SPEED FOLLOWER. 

¥ If you use PI REGULATOR, Preset Speeds 

will override the speed established by PI 

REGULATOR. 

¥ If you use ANALOG LOAD LIM, Preset 

Speeds will override the speed follower 

connected to terminals 1 and 2. 

¥ You cannot override speed set by DIGITAL 

POT, except by load limit. 

¥ The load limit you set (using parameter 22 or 

23) will fold back the speed setpoint when the 

load limit is exceeded.



Integral Gain 



Mnemonic: INTEGRAL GAIN 

Range of Adjustment: 0 to 32,767 



Refer to Remote Function (parameter 23), PI 

REGULATOR for application information. 




Mnemonic: PROPORTIONAL GN 

Range of Adjustment: 0 to 32,767 



Refer to Remote Function (parameter 23), PI 

REGULATOR for application information. 

Preset Speeds 1 through 7 


Parameter Number: 26 to 32 

Mnemonic: PRESET SPEED x 

where ÒxÓ is a value of 1 to 7 


and Maximum Speed. 



These parameters define speeds actuated by a 

remote signal. If the drive is in the KEYPAD 

mode, it will not respond to Preset Speed or Jog 

terminal block connections. If the drive is in 

REMOTE mode, Preset Speed terminal block 

connections override the 0-10 V or 4-20 mA 

speed follower. For a more complete explanation 

of the priority interaction, refer to Remote 

Function (parameter 23), Priority Interaction in 

REMOTE Mode. 

Note that if you use DIGITAL POT (Remote 

Function (parameter 23)), the drive ignores 

terminal 12 and Preset Speeds are not used to 

set the speed setpoint. 

Use the following chart to determine which of the 

seven Preset Speeds are in control. For 

example, if you connect terminals 12 and 7, the 

speed setpoint established by the 

PRESET SPEED 1 parameter will be used by the 

drive: 

Terminals Connected Preset Speed Set 

12 to 7 1 

13 to 7 2 

12 and 13 to 7 3 

14 to 7 4 

14 and 12 to 7 5 

14 and 13 to 7 6 

14 and 12 and 13 to 7 7 

Jog Speed 



Mnemonic: JOG SPEED 


and Maximum Speed 



The Jog function can only be activated via the 

terminal strip when the drive is in REMOTE 

mode. If the drive is at 0 speed or decelerating 

due to a Stop command, and Jog contact is 

closed (terminal 11 is connected to terminal 7) 

and run enable is closed (terminal 8 connected to 

terminal 7), the drive will start and go to the Jog 

Speed you set with this parameter. When the jog 

contact is opened, the drive will go back to 

previous speed command or next highest priority 

speed command. 


4-21



Jump Speeds 1 through 3 


Parameter Number: 34 to 36 

Mnemonic: JUMP SPEED x LO 

where ÒxÓ is a value of 1 to 3 

Range of Adjustment: Minimum Speed to 

Maximum Speed 



These parameters set jump speeds which are 

used to avoid operating at speeds that create 

problems with mechanical resonance. The jump 

speeds, combined with Jump Width (parameter 

37), create frequency windows. The drive can 

accelerate or decelerate smoothly through the 

windows, but will not stop at any frequency within 

a window. Jump frequency windows are 

illustrated in the graph shown below. 

Jump Width 



Mnemonic: JUMP WIDTH 

Range of Adjustment: 0 to Maximum Speed 



This parameter allows you to define the band 

width of frequencies around each jump speed 

where the drive will not operate continuously.

Mnemonic: DC BRAKE TIME 

Range of Adjustment: 0 to 16 sec 


Factory Setting: 0.0 sec 

This parameter defines how long in seconds that 

DC injection braking lasts. When DC current is 

injected into the windings of an induction motor, 

the motor acts as a brake. Approximately 20% 

braking torque is injected for the period of time 

set by this parameter when the motor speed 

drops below 5 Hz. 

Relay 1 and 

Relay 2 


Parameter Number: 39 and 40 

Mnemonic: RELAY 1 or RELAY 2 

Range of Adjustment: One of the following eight 

functions can be selected 

for each of the two relays: 

ÒREADYÓ, ÒRUNÓ, 

ÒREVERSEÓ, ÒKEYPADÓ, 

ÒAT SPEEDÓ, ÒZERO 

SPEEDÓ, ÒLOAD LIMITÓ, 

ÒOVERLOAD WARNINGÓ 


Factory Setting: Relay 1: ÒRUNÓ 

Relay 2: ÒAT SPEEDÓ 

RELAY 1 defines the relay function when drive is 

in RUN mode. RELAY 2 defines the relay 

function when drive is Òat speedÓ.



Analog Output 1 and 

Analog Output 2 


Parameter Number: 41 and 42 

Mnemonic: ANALOG OUTPUT 1 or 

ANALOG OUTPUT 2 

Range of Adjustment: One of the following six 

functions can be selected 

for each of the two 

available analog outputs: 

ÒSPEEDÓ, 

ÒFREQUENCYÓ, ÒLOADÓ, 

ÒCURRENTÓ, ÒMOTOR 

VOLTSÓ, ÒPOWERÓ 


Factory Setting: Output #1: ÒSPEEDÓ 

Output #2: ÒLOADÓ 

This parameter defines the two analog output 

function units. 

Number of Restart Attempts 

Before Lockout 



Mnemonic: RESTART ATTEMPTS 

Range of Adjustment: 0 to 255 



This parameter defines the number of times the 

drive will attempt to restart after a trip. If this 

number is exceeded, the drive faults and the 

appropriate fault designation is shown on the 

LCD. Entering 0 disables auto restart. The restart 

counter is reset every 60 minutes. 

Time Between Restart 

Attempts 



Mnemonic: RESTART DELAY 

Range of Adjustment: 1.0 to 300.0 sec 



This parameter defines the amount of time the 

drive waits between auto restart attempts. 

Stop Profile 



Mnemonic: STOP PROFILE 

Range of Adjustment: ÒCOASTÓ or ÒRAMPÓ 


Factory Setting: ÒRAMPÓ 

This parameter allows you to choose whether the 

motor will coast to a stop or ramp down to a stop 

per the appropriate deceleration time and profile. 

Load Inertia 



Mnemonic: LOAD INERTIA 




This parameter adjusts the internal speed 

regulator based on the inertia of the load. For 

higher inertia loads, the user should set this 

parameterÕs value higher. When tuning this 

parameter, it is most practical to change the 

setting in increments of 10 to 20 units. The value 

Ò20Ó is intended to equal 2 times connected 

inertia. 




Mnemonic: REVERSE DIR. 

Range of Adjustment: ÒDISABLEÓ or ÒENABLEÓ 


Factory Setting: ÒENABLEÓ 

This parameter allows you to enable or disable 

the F/R button on the keypad. 


4-23






Mnemonic: SELECT KEY 



Factory Setting: ÒENABLEÓ 

This parameter allows you to disable the Select 

button and lock the drive into REMOTE or 

KEYPAD operation. 




Mnemonic: EFFICIENCY OPT 

Range of Adjustment: ÒENABLEÓ or ÒDISABLEÓ 


Factory Setting: ÒDISABLEÓ 

Selecting ÒENABLEÓ makes the motor run more 

efficiently by reducing flux in the motor for 

centrifugal loads, but reduces the motorÕs ability 

to change load quickly. Use ÒENABLEÓ whenever 

possible (i.e., unless motor stalls) to save energy. 




Mnemonic: ÒPOWER UP RESTARTÓ 




Selecting ÒENABLEÓ makes the drive restart after 

waiting the period of time set in Parameter 44 

(RESTART DELAY) if power is applied in the 

REMOTE mode with the Start and Stop/Run 

Enable inputs closed. 

Selecting ÒDISABLEÓ requires a transition on the 

Start or Stop/Run Enable inputs for the drive to 

restart. 


4-24 




Mnemonic: SPINNING MOTOR 




This parameter should be disabled when you run 

multiple motors from the same drive. 

If this parameter is enabled, the drive will search 

for the speed of the motor in the commanded 

direction. If the speed is not found, the drive will 

search in the opposite direction of the 

commanded direction. If the speed is still not 

found, the drive will assume the motor is at rest 

and initiate a normal start. Therefore, a 1 to 3 

second delay in start time will occur when the 

Start Into Spinning Motor parameter is enabled. 

If only one motor is connected to the drive, you 

can enable the parameter so the drive ÒcatchesÓ 

the load at the speed it is running and ramps it to 

the last speed command issued by the drive. If 

the motor is turning in the reverse direction to the 

last command sent by the drive, the drive will 

ÒcatchÓ the motor, ramp it down to 0 Hz, and 

ramp it up to the speed and direction last 

commanded by the drive.



Fault History 



Mnemonic: ÒLAST FAULTÓ, or ÒLAST FAULT 

TIMEÓ, or PREVIOUS FAULTÓ or 

ÒPREV. FAULT TIMEÓ or ÒFIRST 

FAULTÓ or ÒFIRST FAULT TIMEÓ 

Range of Adjustment: N/A 

Run Locked?: N/A 

Factory Setting: N/A 

This parameter aids in troubleshooting by 

displaying the most recent fault that has 

occurred, the fault just prior to the most recent 

fault, and the first fault that has occurred. 

When a fault occurs, the drive enters the FAULT 

mode. In the FAULT mode, the Fault indicator is 

illuminated, the keypad is put into SCROLL mode 

and the last fault is displayed. 

If you press the Up or Down buttons you can 

scroll through the parameters, starting with the 

fault display. 

If you press the Operate button, the two 

Operation Displays, specified by the Upper and 

Lower parameters, will appear. The Fault 

indicator remains lit until you resolve the problem 

and press the Start or Stop button. 

The upper line on the LCD will display one of the 

messages shown in the Range of Adjustment 

column. The lower line displays the fault or time 

(elapsed time in hours, resets to 0 when 6553.5 

hours are exceeded) message. 

Password 



Mnemonic: PASSWORD 




This parameter sets password protection. The 

password is set by changing from 0 to any other 

value. To change the password to a new value: 

1. Scroll to the Password parameter, see 

Section 3, Selecting the Parameter to set. 

2. Enter the current password. See Section 3, 

Changing the Parameter Settings. 

3. Press the Setup button. 

4. To change the password, press the Up or 

Down buttons until the new password 

appears. 

5. Press the Setup button. 

Changing the password to 0 clears the password. 

If you enter a password, begin making changes, 

and then walk away, there will be a time out if 

there is no keypad activity within a five minute 

period. Then you must reenter the password in 

order to change parameter settings. 

Remember to put your password in a safe 

place. 

If you forget the password you set, contact your 

local Cutler-Hammer distributor who can 

reestablish your password with special operation.

2. Press the Operate button, (the Operate LCD is lights). 

3. Jumper terminal 7 to 8 and terminal 7 to 15. 

4. Press and hold the Operate button and press the Start button. 

5. Release both buttons. 

In the OPEN LOOP TEST Mode the keypad LCD displays the output 

voltage, speed, and frequency. Load and current values should be 

zero. Note that if you try to connect a motor to a drive in the OPEN 

LOOP TEST Mode, the drive will trip after 5 seconds and display 

ÒMotor Fault.Ó The drive will also trip on Motor Fault if you try to run 

with no motor connected in the default CLOSED LOOP Mode. 

To return to the default CLOSED LOOP Mode, press the Stop button.

This indicates that the 

internal DC bus is too high 

for safe operation. 

Analog sensing circuits 

cannot auto-calibrate. 

Suggested 

Remedies 

If fault recurs, contact your 

Cutler-Hammer service 

representative. 

1. Check motor leads. 

2. Try different motor. 

3. Reduce load on motor. 

1. Check for problems on 

input line circuit such 

as input line 

transients. See 

Section 2, Input Line 

Considerations and 

Specifications. 

2. Check for motor 

problems. 

1. Make sure each input 

line voltage phase is 

present (Drive 

terminals L1, L2, and 

L3). 

2. Check for excess line 

impedance. 

1. Check for high line 

voltage at each input 

phase (Drive terminals 

L1, L2, and L3). 

2. Check for regenerative 

load. 

If fault recurs, contact your 


representative.

Checking DC Bus Voltage 


Step 1. Set a digital volt meter to read DC volts, 

and use the 0 to 1000V scale. 

Step 2. Connect the digital volt meter between 

the ÒAÓ and ÒBÓ terminals of the capacitor 

assembly as shown in Fig. 5-1. 

Step 3. Monitor the bus voltage until it reaches 

zero volts DC. 


5-6 

! Danger High Voltage 

Internal parts of the drive are at line voltage 

when AC power is connected to input terminals. 

This voltage is extremely dangerous and can 

cause death or serious injury. When the supply 

is disconnected from the input terminal block, it 

will take up to 10 minutes before the DC bus 

capacitors are discharged to a safe voltage. 

To ensure the voltage is safe, monitor the 

capacitor discharge with a digital voltmeter 

connected between the ÒAÓ and ÒBÓ terminals on 

the capacitor assembly as described. Do not 

work on the drive until the capacitors have 

completely discharged. Do not attempt to 

discharge the capacitors by short circuiting the 

bus.
