With many essential features built in, including PLC capabilities for simple programming needs, dual STO safety function, braking transistor and PID control, it provides a compact solution for any installation.

Excellence in Motor Control



The Ultimate All-In-One Drive  

Adaptable to your application
Whether you have a single application or a variety of different ones, Commander C fits right in. With all essential features built-in, it's ready to go right out of the box.

Integrated functional safety

The Dual Safe Torque Off (STO) feature, certified to the highest level of machine safety, SIL3/PLe, and compliant to EN/IEC 61800-5-2, prevents the motor from moving unexpectedly, protecting both equipment and operators.

On-board PLC
The generous 30kB user space allows for add-on programmable functions, more elaborate I/O features and special software that enables greater machine control. The on-board PLC also eliminates the need for an external controller, saving both on cost and space.
Compact design
Commander C is one of the most compact drives within its category, taking little space in the cabinet and minimizing installation cost.

Super quick start-up
To get started you only need to set-up 4 parameters (motor rated current, RPM, voltage and power) and for your convenience we've listed them on the front cover of the drive.

Flexible connectivity
The plug in communication modules enable integration with the most common industrial fieldbuses.
Worldwide availability and outstanding service
Need expert advice and support? Wherever you are in the world we've got you covered via our sales offices or Control Techniques approved distributors.
Free 5 year warranty
Our Commander C series is built to cope with harsh environments.
To share our confidence in the reliability of Commander C we offer an extended 5 year warranty, at no extra cost. 
It is a testament to our exceptional track record for reliability, giving you total peace of mind that your investment is protected and your site will continue to run uninterrupted.
