Servo drive CMMT-ST

The extremely small servo drive CMMT-ST positions and moves highly economically, dynamically and precisely up to 300 W, point-to-point or interpolating. It is also commissioned simply via Festo Automation Suite and integrated Auto-Tuning in the shortest of time.
  • Very efficient for tasks with low power requirements
  • Ideal for positioning tasks and point-to-point and interpolating motion solutions
  • 50% more compact than the smallest servo drive CMMT-AS
  • 150 W at 24 V DC, 300 W at 48 V DC
  • When operating with the available 24 V DC network in a control cabinet and a continuous output of 150 W, there is no need for an extra power supply unit
  • With safety functions
  • Optimised for use with stepper motors like the tried-and-tested EMMS-ST

Servo drive CMMT: the highlights presented by the Product Manager

Even small automation tasks, such as simply moving a workpiece from A to B, can turn into an endless undertaking and a complex project, making commissioning take even longer.
See how to make it faster and easier in the video:

Festo Elevator Pitch: the servo drive CMMT-ST

With our CMMT-ST you can implement axes with up to 300 W continuous output.

2. Extremely compact

50% more compact than the smallest CMMT-AS with almost the exact same performance

3. Commissioning

Commissioning with the Festo Automation Suite is error-free and takes just a few minutes

4. Parameter sets

  • Optimal parameters for optimised cycle times and process reliability
  • Save up to three parameter sets on the drive for complex applications

5. Integrated standard safety

  • STO: safe torque off (SIL3/cat. 3 PL e)
  • SS1: safe stop 1 (type c) when using a suitable external switching device and a suitable circuit
  • Configuration without software possible

6. Motor connection and encoder interface

Motor connection of firmware and parameters:

  • Optimal with proven stepper motor EMMS-ST from Festo
  • Suitable for BLDC motors (brushless DC motor)

Encoder interface:
For greater positioning accuracy of the axis mechanism

7. Dynamic movement and precise positioning

  • Point-to-point
  • Interpolating

8. Technical data

  • Max. continuous output: 300 W
  • Primary voltage: 24...48 V DC
  • Motor current: 8 A/peak 10 A
