Nidec Commander C - the 6th generation of general purpose drive

Control Techniques has set the standards in motor control since 1973.
New Commander C series is based on six generations of technical knowhow and expertise. It’s flexible. It’s versatile. It’s up to whatever challenging application you want to throw at it. And thanks to its ground-breaking design, the new series is super quick and easy to set up too. To put it simply, it’s the best performing, most reliable and energy efficient general purpose drive we’ve ever built.

Free 5 year warranty
Commander C series is built to cope with harsh environments. In fact, it is so reliable we are confident enough to supply it with a free five-year warranty.

Nidec Commander C key features

Easy installation & commissioning
We’ve put the parameters you need on the front of the drive for easy reference.

Exceptional starting torque
Up to 180% overload for high torque applications.

Integrated functional safety
The Dual Safe Torque Off (STO) feature, certified to SIL 3/PLe safety rating and compliant with EH/IEC 6/800-5-2, prevents the motor from moving unexpectedly and can also be used to implement emergency stop without contactors.

Onboard PLC
Embedded intelligence eliminates the need for an external controller, saving both on cost and space when installing Commander C drives into a system.

Super-quick start-up
Tap in 4 key parameters (the motor rated current, RPM, voltage and power factor) and off you go.

Equipped with the latest energy saving features
The latest energy-saving technology means you get high productivity and low running costs.

Flexible connectivity
The plug in communication modules enable integration with a wide range of industrial fieldbuses

Input / Output



Intuitive commissioning software
For fast task based commissioning and easy maintenance Connect offers a familiar Windows™ interface and intuitive graphical tools to enhance data analysis.

The dynamic drive logic diagrams allow the visualisation and control of the drive in real time. The parameter browser enables viewing, editing and saving of parameters as well as importing parameter files from our legacy drives.

Advanced machine control
For more advanced applications Machine Control Studio provides a flexible and intuitive environment for programming. This is possible thanks to the onboard PLC that increases the drives functionality at no extra cost.

Control Techniques also provides support for customers’ own function block libraries, with on-line monitoring of program variables with user defined watch windows and help for online change of program, in line with current PLC practice.
