The extremely small and highly economical CMMT-ST with multiprotocol

You can easily set the required Ethernet protocol manually on the servo drive using a DIL switch or, even more simply and conveniently, select it directly during commissioning in the Festo Automation Suite.

Seamless connectivity: servo drive CMMT – from 50 W to 12 kW

Servo drives control servo motors, and they thus regulate rotary applications and, in combination with an axis, the linear movements in a machine. Servo drives are a core automation technology. With the CMMT range, we offer the right technical competence and experience.

1. Ethernet-based communication

  • One servo drive platform for numerous fieldbuses
  • Easily integrated into automation solutions with controllers from, for example, Siemens, Rockwell, Beckhoff and others

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
