Unidrive SP - Incorporating “Benchmark” Technologies 

SECURE DISABLE 

The Unidrive SP Secure Disable function meets the 

requirements of EN954-I : category 3 for machine safety, 

and can serve as a part of a category 4 application. 

Control Techniques’ Secure Disable safety solution has 

been independently verified by the German safety 

organization, BIA. This exclusive 

feature of the Unidrive SP saves 

money and space. Under many 

conditions, this standard feature 

eliminates the need for safety 

contactors by utilizing secure 

circuitry to prevent the motor 

shaft from being driven by the 

drive. 

MULTIPLE FIELDBUS CAPABILITY 

The Unidrive SP provides unrivaled fieldbus flexibility. In 

addition to the standard Modbus RTU port, up to three 

fieldbus option modules can be installed in the Unidrive 

SP’s option slots. This provides the capability to control 

and monitor a Unidrive SP on multiple fieldbus networks. 

For example, a single Unidrive SP can be configured to 

communicate on both DeviceNet and Profibus networks 

simultaneously. 

In the example shown, CTNet is used to provide 

real-time coordination between two Unidrive SP 

modules. The DeviceNet and Profibus connections allow 

data to be passed to/from the controllers in a machine 

line. 

PLC FUNCTIONALITY WITH UNIDRIVE SP 

In addition to the extensive drive configuration 

capabilities of the Unidrive SP, scalable programming is 

available to solve virtually any application requirement. 

Simple logic function programming is achieved using 

SyPTLite software and the drive’s built in PLC. More 

complex systems can be solved by adding 

SM-Applications Lite (with SyPTLite or SyPTPro) and 

SM-Applications (SyPT only) option modules.

Note: Motor horsepower ratings are based on typical motor current ratings. Actual motor currents should be checked before selecting a particular drive. For some high 

effi ciency motors, the required full load motor current may allow the selection of a smaller drive than is indicated in the chart. The same consideration would also apply for 

motors with less common power or voltage ratings. 

Normal Duty 

Suitable for most applications, current overload is set 

at 110% for 60 seconds. Where motor rated current 

is less than the drive rated continuous 

current, higher over loads are achieved. 

Heavy Duty 

Suitable for demanding applications, current 

overload is set at up to 175% for 40 seconds. Where 

motor rated current is less than the drive rated continuous 

current, higher overloads (200% or greater) 

are achieved.

Power Accessories 

INTERNAL DYNAMIC BRAKING RESISTORS 

During deceleration, the mechanical 

energy stored in the spinning mass of 

the motor and load is converted to 

electrical energy, which recharges the 

drive’s DC bus. Dynamic braking 

resistors provide a means of rapidly 

dissipating that energy so that the 

drive does not fault from overcharging 

the DC bus. The ohmic value and 

power rating of the braking resistor is a 

function of the drive type and size. 

A zero-space braking resistor is available for heatsink 

mounting on Unidrive SP frame sizes 1 and 2. These 

resistors are designed for low-inertia loads commonly 

used in servo type applications. For higher-inertia loads, 

the heatsink mounted resistor may not have enough 

braking capacity, and a larger external resistor may be 

required. No thermal protection device is required with 

these heatsink-mounted resistor packages.

EXTERNAL EMC FILTERS 

EMC filters are used to minimize high frequency power 

supply line disturbances caused by PWM AC drives 

that may interfere with proper operation of sensitive 

electronic equipment. These specific filters have been 

assessed for conformance with the EMC directive by 

testing with the appropriate Control Techniques drives. 

The filters used with Unidrive SP 

have been designed to mount in 

either Footprint or Bookend 

dimensions, allowing the user to 

optimize panel space.

SYPTLITE AND SYPTPRO 

Control Techniques has developed a programming tool 

called SyPT (or System Programming Tool) for OEM’s and 

End Users that allows engineers and machine designers 

to maximize the functionality of the Unidrive SP and 

other Control Techniques drives. Whether programming a 

simple single-drive application that requires Run and Stop 

controls, or fully networked multi-drive control systems 

for machine and process control applications, SyPT helps 

the user to solve the application. 

To cover the wide range of application complexity, SyPT 

is available in two versions called SyPTLite and SyPTPro. 

SyPTLite is used to creat simple or complex Ladder Logic 

programs that can be used to control the drive, and even 

to replace small PLC’s that control machine I/O. SyPTPro 

is for the advanced machine programmer, and gives the 

user IEC-61131-3 sytle programming with Ladder Logic, 

Function Block, and DPL (text-based) editors. SyPTPro is 

used for complete machine control and/or motion control 

by configuring all drives and control modules, as well as 

replacing costly PLC’s used just for machine I/O.

Fan & Pump Duty Assist 

The Duty-Assist control is an effective method of 

controlling multiple pumps or fans in parallel to maintain 

the required process demand. Pumps and fans are often 

used in parallel banks to avoid motor overload, guarantee 

security of supply through system redundancy, reduce 

running costs due to system load cycles, and provide a 

wide range of control and flexibility. 

The system consists of a ‘Duty’ Drive and assist starters. 

The assist starters can be of any type, (e.g, Contactor,
