Flexible drive control

March 2019 Motion Control & Drives

One module fits perfectly with another: a complete drive system consisting of the servo drive CMMT-AS and servo motor EMMT-AS from Festo enables complete connectivity in hardware and software. Users can commission the complete drive system consisting of the servo drive, servo motor and mechanical system in only three minutes.

The compact servo drive is an integral part of the Festo Automation Platform. It is designed for dynamic motion, point-to-point and interpolating in demanding applications such as assembly and handling technology, for packaging machines or in the electronics industry. It is perfect when combined with the AC synchronous servo motor.

Due to the ‘closed-loop controller concept for Ethernet-based bus systems’ the servo drive enables seamless fieldbus integration with the products of most controller manufacturers. This also applies to the simple integration of the servo drive into application programs, including controller-specific function elements, for example from Siemens, Rockwell or Beckhoff.

The auto-tuning function supports the easy commissioning of rotary and linear movements, which automatically optimises the control behaviour of the connected servo motors and linear mechanisms from Festo. Furthermore, the function supports the mechanical systems of third-party suppliers during commissioning.

The EMMT-AS is an AC synchronous servo motor for demanding and dynamic applications. The connection of the motor using a single-cable solution for the power supply, the encoder and the brake, reduces the installation effort and saves space in the control cabinet. It is characterised by a low detent torque. It is therefore easy to regulate and guarantees path accuracy for both linear and rotary positioning tasks.

Quick commissioning

Easy, reliable and fast commissioning is made possible by the integrated electronic rating plate, which contains all the relevant motor data and can be read directly from the unit.

The free Festo Automation Suite is the main software of the constantly expanding Festo Automation Platform, which is entering the automation market with numerous new products and solutions from the mechanical system to the cloud. It combines the parameterisation, programming and maintenance of Festo components in one program, and enables the commissioning of the entire drive package, from the mechanical system to the controller in just a few intuitive steps.
