Servo drive CMMT-AS

The servo drive CMMT-AS at a glance

The price- and size-optimized, compact servo drive CMMT-AS is an integral part of the automation platform from Festo. Suitable for point-to-point and interpolating motion, CMMT-AS can be commissioned with the Festo Automation Suite in just a few minutes – with no errors!

The servo drive is suitable for different Ethernet-based bus systems and can be smoothly integrated into the controller environments of various manufacturers. Controller-specific function blocks are included for this.

Servo drive CMMT: The highlights presented by the Product Manager

Even small automation tasks like simply moving a workpiece from A to B can become an endless undertaking and a complex project – making commissioning take even longer.

1. Ethernet-based communication

One servo drive platform for numerous fieldbuses

Easily integrated into automation solutions with controllers from Siemens, Rockwell, Beckhoff and others, for example

Logos Ethernet-based communication

2. Compact design

All connections and the operating panel CDSB are at the front and on top of the closed-loop controller

3. Function blocks

Simple integration in automation solutions. For example from Siemens, Rockwell, Beckhoff, etc.

Quick implementation of point-to-point motions and interpolating motions

4. Parameter sets

Optimal parameters for optimized cycle times and process reliability

Save up to 3 parameter sets on the closed-loop controller for complex applications

5. Integrated safety and reliability

Standard protective functions:

  • STO: safe torque off (SIL3/cat. 4 PL e)
  • SS1: safe stop 1 (Type c) when using a suitable external safety relay unit and suitable circuits
  • SBC: safe brake control (up to SIL3/cat. 3 PL e)
  • Diagnostic outputs STA and SBA for feedback of the active safety function

Extended safety functions such as SS2 (Safe Stop 2), SOS (Safe Operating Stop), SLS (Safely Limited Speed) or SSR (Safe Speed Range) in preparation

Standard safety functions can be configured without software

6. Encoder interfaces

Multi-encoder input for motors

Input for 2nd encoder:

  • For safety-oriented 2-channel solutions with redundant measuring system
  • For greater positioning accuracy of the axis mechanism
  • For special applications (e.g. flying saws)
  • For synchronization of two axes

7. Motor connection

The servo motor EMMT-AS is connected with one cable plug (OCP)

Other servo motors are connected with separate cables

8. DC link coupling

Return energy feed via the DC link

9. Operating panel CDSB

Control element with touchscreen and USB interface

Simple, full-text diagnostics and setting of the closed-loop controller on site
