3.3 Installation 

3.3.1 Amplifier Installation Precautions 

The amplifier must be installed in an enclosure. Carefully consider the size of the case, the cooling 

method, and the location so that the ambient temperature around the amplifier does not exceed 55°C.For 

longevity and high reliability, it is recommended to keep the temperature around the amplifier below 40°C. 

The amplifier has an internal overheating detection function. Consider the cooling method to be used if an 

amplifier overheating error is detected. 

If there is a vibration source nearby, use a shock absorber between the amplifier and the installation base 

to prevent the vibration from directly affecting the amplifier. 

Long-term use in the presence of corrosive gas may cause contact failure on the connectors and on 

connecting parts. Never use the device where it may be subjected to corrosive gas. 

Do not use the device where explosive or combustible gas is present, as this could cause fire or an 

explosion. 

Do not use the device where dust or oil mist is present. If dust or oil mist attaches to and accumulates on 

the device, it can cause insulation deterioration or leakage between the conductive parts, and damage the 

amplifier. 

A large noise source may cause inductive noise to enter the input signals or the power circuit, and can 

cause a malfunction. If there is a possibility of noise, insert a noise filter, inspect the line wiring and take 

appropriate noise prevention measures. 

3.3.2 Amplifier Installation Method 

1) Installation dimensions 

The amplifier must be installed using two M4 screws on its rear panel. Refer to the amplifier outline 

drawing (Section 7.5.1) for the installation dimensions. 

2) Installation direction 

The amplifier uses natural convection cooling. The installation direction must be vertical. Do not install 

the unit upside down. 

3) Installing multiple amplifiers in a row 

Leave at least 50mm of space above and below the amplifiers to ensure unobstructed airflow from the 

radiator. If heat gets trapped above the amplifier, use a fan to create airflow. Leave at least 10mm of 

space between the amplifiers. 

 

3-3


3.3.3 Motor Installation Precautions 

If the motor is enclosed in an enclosure, consider its size, the use of a heat sink, and ensure the 

temperature inside the case is between 0 and 40°C. 

Consider a radiation method to ensure that the surface temperature of the motor (end cap surface 

temperature) does not exceed 85°C. (If the motor overheating prevention function is working, an ALM will 

be detected.) 

When installing a pulley or a gear to the motor, avoid methods such as press fitting that apply force in the 

torque direction. Ensure accurate shaft centering when integrating the rotating shaft of the motor with the 

target machinery. Incorrect centering can damage the shaft and the bearings. 

Avoid installation in places where the unit may be subjected to water, cutting fluid, rain or conductive 

particles such as dust and iron filings. 

Never install the unit where it could be subjected to corrosive (acid, alkali, etc.), flammable, explosive liquids or 

fumes. 

Avoid installing the motor on moving parts. Since the wires and cables used for this device are electric 

connection wires, disconnection could occur. Contact the manufacturer for assistance for use on moving parts. 

If a belt-drive is used, verify that the gear reduction value of the belt tension does not exceed the thrust 

load tolerance. Refer to 7.2 and 7.3.) 

3.3.4 Motor Installation Method 

Use the tap hole or mounting hole on the installation surface and the mounting rabbet for installation. Refer 

to the outline drawing (Section 7.5.2) for the tap hole pitch measurements and the mounting rabbet

3.4 Wiring 

3.4.1 Wiring Precautions 

1) Noise protection 

Follow the instructions below to prevent malfunctions due to noise. 

The noise filter, amplifier and the host controller should be placed at the minimum distance. 

Apply a surge absorber circuit to coils such as relays, electromagnetic contacts, induction 

motors and brake solenoids, etc. 

Do not enclose the power lines, the motor lines, and the signal lines in the same wire 

conduit; they are not intended to be bundled together. 

If there are large noise sources such as electric welding machines or electric discharge 

machines nearby, apply a noise filter for the power line and the input circuit. 

Do not bundle the primary and secondary wiring of the noise filter together. 

2) Wiring 

Perform wiring only when power is cut off. Carefully verify that wiring is correct, as faulty wiring 

can cause damage to the device. 

3) Cables for wiring 

Use the correct size of cables as specified for wiring. (Refer to Section 3.4.3) 

4) Emergency stop circuit 

Be sure to install an external emergency stop circuit that can stop the device and cut off the power 

instantaneously.

3.4.5 Grounding 

Amplifier grounding: Ground the amplifier using the grounding wire from the ground connector 

(M4) of the amplifier case. Use single point grounding with a minimum of AWG 16 wire 

(1.25mm 2 ). 

Motor frame grounding: If the motor is grounded through the frame, then Cf x dv/dt current 

flows from the PMW power part of the servo amplifier through the motor floating capacitance 

(Cf). To prevent the effects of this current, use single point grounding for the motor frame and 

the servo amplifier ground. Use at least AWG18 wire (0.75mm 2 ) for grounding the motor. 

Grounding the wiring: If the motor is wired to a metal conduit or metal box, the metal must be 

grounded. Use single-point grounding. 

 

3.4.6 Short-circuit Breaker 

Due to the noise filter of the power input unit and the high-frequency switching noise of the PWM 

control, a high frequency leakage current may occur at the servo amplifier. If a short-circuit breaker is 

used to prevent malfunctions, use a high frequency leakage breaker. 

3.4.7 Motor and Encoder Wiring (CN 2,3) 

Connect the connectors of the encoder / motor cables (including the holding brake connections) to 

CN2, CN3 of the amplifier. The standard length of the motor / encoder cable is 0.5m. Use a relay cable to 

extend the wiring length, if necessary. 

* The encoder connector cable contains a motor overheating detection line. If an extension cable is 

used, this line must also be connected. 

* The holding brake is polarized. If an extension cable is used, verify the pin assignment (Section 

3.4.4) for correct polarization. The holding brake control function is built into the amplifier. 

3.4.8 Power Wiring 

Connect the AC power to Pin 1, 2 of CN4. 

The following table shows the power specifications: 

 

Motor Model PBM423 PBM603 PBM604 PBM861 PBM862 

Power voltage specification AC100V - 230V –15% to +10% 50/60Hz 

Current capacity (A rms) See Section 7.4 

* Pins 3 and 4 of CN4 are for connecting the regeneration unit, required if a regeneration error ALM 

occurs due to reasons such as moving a negative load. Normally, regenerative control is 

performed internally by the amplifier, so there is no need to connect an external unit. 

* Pins 4 and 5 of CN4 are the FG terminals. Use them when connecting to the motor case. 

(Use the M4 screw that was installed on the case as the amplifier ground terminal.)

4.4.2 ALM Conditions and Causes 

ALM Code ALM Description Condition / Cause 

CPU error Indicates a CPU error (W.D). 

Possible causes 

Problem with the amplifier internal control power. 

CPU malfunction due to excessive noise. 

01h Sensor 

disconnected 

Indicates the disconnection of the sensor A/B-phase. 


Sensor line wiring problem. 

Error detected due to excessive noise on the sensor line. 

* Disconnection of the C-phase is detected during zero-return (at C-phase detection 

type) as a zero-return error. 

02h Over-voltage Indicates that the input power voltage is above the specification range. 

At power-up, the amplifier automatically recognizes 100/200V power voltage. 

After the voltage detection, over-voltage is determined based on the following values: 

100V input: approx. 138V AC 


* Not detected during servo ON. 

03h Under-voltage Indicates that the input power voltage is below the specification range. 

At power-up, the amplifier automatically recognizes 100/200V power voltage. 

After the voltage detection, under-voltage is determined based on the following values: 



* History record of under-voltage error detected during the amplifier’s internal voltage 

stabilization period when turning the power off is not recorded in the ALM history. 

The ALM history is saved if the voltage returns to normal after under-voltage 

detection due to instantaneous under-voltage. 

04h Initialization error After the power of the PB system is turned on, tit detects the initial phase, initializes the 

internal counter, and switches to servo ON status. If the sensor initial phase cannot be 

detected correctly, it results in an ALM condition. 


Sensor C-phase disconnection. 

The load reached the mechanical limit. 

Load is out of tolerance range (excessive load). 

* If there is an ALM or STOP status after the power is turned ON, the process will not be 

executed.

4.6 Adjustments 

4.6.1 Command 21h 

Adjustments can be made to the proportional gain and the integral gain of the velocity loop from 

16 levels of normalized settings. 

The proportional gain is set based on the SW setting value, and increased gradually. 

The integral gain is selected from 3 levels. 

The setting values for the Gain Table are shown below: 

SW Setting 

Proportional 

Integral Gain 

SW Setting

5 14 20 D 30 10 

6 16 1 E 32 20 

7 18 10 F 34 1 

Adjustment method 

Increase the level gradually (0h→3h→6h→...), as long as there is no oscillation in the motor or 

the load, and select the proportional gain. As the level increases, the gain also increases, and 

the velocity waveform changes as shown below. By increasing the proportional gain as much 

as possible without oscillation, high response can be achieved. 

Low proportional gain 

High proportional gain 

Next, select the integral gain (time constant), while checking the load response and the 

In-Position status. As for the integral, the time fixed number becomes big as raise the 

numerical value. 

4.6.2 Command 2Fh 

Command 2Fh can coordinate proportional and integral gain individually. 

When a fine adjustment of gain setting is necessary, please use this. 

* Proportional Gain: Please do not set 0. 

* Integral Gain: When set the 0, it does not arrive at order speed.

5.4.4 State control Command 



Brake Enable 


DAT1 Brake Enable 0 to 1 0=Release; 1=Engage 

Directly controls the holding brake status during servo OFF (including Alarm and STOP status). 

* This status is not saved in the non-volatile memory. (Normally 1 after powering up.) 

When switching to servo ON, the status is automatically set to 1, and unless 0 was preset, the 

holding brake will be engaged when a STOP or ALM occurs. 



Deviation Clear 

This command initiates deviation clear. The position at the time of receiving this command becomes the 

target position. 

* Note that if the command is sent during rotation, it returns to the original position using the excess 

deceleration distance. 



Pause Command 

This command initiates a Pause (temporary stop). The target position is held, and a deceleration stop is 

performed based on the current deceleration rate settings. When Pause is cancelled, the move to the 

target position resumes. 

* If the Pause function is allocated to an input port, it will operate with an OR condition with this 


* The Pause input function is allocated by command 16h. 



Pause Clear 

This command cancels the Pause, and at the same time, moving to the target position resumes. 

* If the Pause function is active at the input port, it will not be cancelled. 



Alarm Clear 

This command clears the alarm. 

* Non-recoverable alarms are not cancelable; they can be cleared only by restarting the power, or 

using the initialization command. 

* If the ALM clear function is allocated to an input port, it will operate with an OR condition with this

* This command is valid only at generic output ports set for output port functions using command 

16h. For non-generic outputs, this function will be ignored. 



STOP Command 

This command initiates an emergency stop. If the motor is in motion, it stops with the maximum 

possible deceleration rate, and the amplifier status changes to servo OFF. 

* The command operates using an OR condition with the STOP input port. 

* If used during program execution, the program execution will stop. 



STOP Clear 

Cancels the STOP initiated by a STOP command. At the time of the STOP clear, the amplifier status 

automatically changes to servo ON. 

* This command does not clear the STOP signal at an input port. 

Command Code: 78 (4Eh) 


Interlock 

This command aborts movement. A deceleration stop is performed using the deceleration rate set at 

the time of receiving the command. The stop position becomes the target position. The system keeps 

the SON status, and performs a deceleration stop. Move commands during interlock will generate a 

command error. 

* During interlock, initialization is not executed. 

Command Code: 79 (4Fh) 


Interlock Clear 

Clears the Interlock initiated by an Interlock command.

When a Timer Wait is executed in STEP mode, the setting time of the Timer will be disabled. 

 

 



Program Stop 

This command aborts the program operation. The amplifier maintains the servo ON status. 

* Program lines that have already started execution will not be aborted. To abort the movement itself, 

use the STOP command. 

* The Program stop command can only be used during program execution; otherwise, a command 

error will be generated. 

* Refer to command code 8Ah to read the stopped program line. 

5-33




Zero-return Store 

This command stores the details of the zero-return operation to be started by a zero-return start signal 

at a generic input port, as specified by command 16h. The setting is stored in the system’s non-volatile 

memory. 

Execution starts by command code 54h, or by the zero-return start signal. 

The content of the zero-return operation is the same as command 45h. Refer to 45h for more 

information. 

The settings will be cleared by command 5 (Point CLR). 

* For verification, use command code 81h, Point No=80h to read the setting. 



Zero-return Start 

This command remotely (via communication) executes the zero-return operation set by command 53h. 

Since there is no default factory setting for zero-return, the user is required to store the data using 

command code 53h before using this command. 

* If no data has been set, a command error is generated, or if execution was initiated by the 

zero-return start signal, the Ack signal output will not respond.

Packet Length 

Contains the length of one packet in bytes in hexadecimal notation. Indicates the total number of 

transmitted bytes from the packet length to the checksum. 

Packet length = Number of databytes (N) + 4 

Address 


Address 

A maximum of 16 amplifiers can be connected. This value specifies the address set by the rotary 

switch. Address=FFh simultaneously specifies all the amplifiers connected to the communication line. 

In this case only the amplifier at address 0 will respond. 

Command Code 

Specifies the command code defined in Chapter 5. 

Data 

The number of data bytes depends on the command. The data fields contain the actual data for each 

command. Data longer than 2 bytes is sent in lower-higher order. 

Checksum 

The checksum is calculated by adding all bytes except the checksum, and taking the lowest byte.

6.3 Communication Method, Timing Chart 

6.3.1 Communication Method (Normal operation) 

Command issue 

Status response 

 

 

Time until the slave sends the status response after receiving the command: Minimum [T1] / 

Maximum [T2] 

Time until the master is able to issue commands after receiving the status: Minimum of 1ms 

1) The master sends all commands with an address attached to the header (Packet length). 

2) Slave devices can only transmit immediately after receiving a command with their own address. 

3) Slave devices send the status response with their address attached to the header. 

4) After receiving the command, the slave device must start responding after [T1] but before [T2] is 

over. 

5) After the master receives the response from the slave, it can issue the next command after [T1] 

has passed. 

6) If there is no response from the slave after [T3], it will be considered a time-out error, and the 

master can issue the next command. (It is possible to re-issue the command.) 

7) If the slave doesn’t complete receiving the data until [T3] is over, it discards the data received, 

and interprets the next data as a header (packet length). 

8) If there is a communication error, the master stops issuing commands after [T3] and clears the 

receive buffer of the slave device. 

9) If there is a communication error, the slave discards the data received, and does not send a 

response. A communication error is shown by opening the line longer than [T3]. 

10) If the slave receives a command that is not a pre-set command, it returns the command error 

status. 

Note 1: During control power connection / cutoff, when the CPU is not working due to unstable 

control power, the amplifier may output some arbitrary data, which should be ignored by the user.

2) If abnormal data is generated 

Abnormal data

Communication error occurred due to noise, etc. 

Master 

Command execution 

Slave 


 

 

i) In the case of abnormal data (packet is not recognizable), the master stops issuing of commands for at 

least [T3]. 

ii) If there is no communication for at least [T3], the slave discards the previously received 

unrecognizable data. If the communication continues after [T3], the first data is interpreted as the 

header (packet length). If the packet is recognizable, it will be processed normally. 

6-6


6.4 Standard Response Time Values 

[T1]=500μsec×2 n (n=0 to 7) setting is possible (command code 10h). 

Based on the T1 setting, [T2]=[T1] x2, [T3]=[T1] x4 will be set. 

Standard values for [T1] to [T3] are shown in the table below.
