IO-Link compatible low cost servo drive controller

29 October 2015

Festo has launched the CMMO-LK low cost drive controller, the world’s first IO-Link controlled servo drive.

The CMMO-LK can be connected with any IO-Link master or any Modbus TCP Ethernet port, allowing for easy system integration across many applications. 
“The use of electrically operated actuators in industry is not new, Festo has had belt drive, ball screw, lead screw and linear motor versions of our pneumatic axis for many years,” begins Nigel Dawson, electric drives product manager at Festo. “But often, driven by servo motors, these solutions are only commercially viable for the most arduous demands on accuracy and loads. We’ve taken our popular ServoLite controller, improved the performance, reduced the size, cost and power consumption to produce the CMMO-LK controller, specifically designed for our new range of actuators in the Optimised Motion Series.”
There is no need to buy or download specialist software for commissioning, the controller carries its own web server allowing customers to parameterise it with any web browser on any type of computer. The system will even automatically connect to the Festo cloud parameter server to ensure it has the latest parameters for motor, axis and controller, so tuning is optimised for the user. 
With features such as safe torque off, integrated inputs for referencing and Ethernet diagnostics, this compact controller offers significant time and cost saving features. A file is provided with the CMMO-LK to ensure simple set up allowing machine builders to ‘plug & play’ almost instantly. 
“Compatible with all electric actuators from Festo, the CMMO-LK is very flexible and can be connected to all fieldbus systems simply via the Festo CPX automation platform. IO Link integration ensures seamless device replacement as all parameters are stored in the IO Link master and the integrated encoder function means true servo functionality in a compact 24v package,” added Nigel.
