The servo drive CMMT-AS at a glance
The price- and size-optimised compact servo drive CMMT-AS is an integral part of the automation platform from Festo. Suitable for point-to-point and interpolating motions, 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 using the controller-specific function blocks that are included.
The compact and powerful CMMT-AS 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 Siemens, Rockwell, Beckhoff and others
2. Compact design
All connections and the operating panel CDSB are on the front and top of the drive
3. Function blocks
Easy to integrate in automation solutions, for example, from Siemens, Rockwell and Beckhoff.
Quick implementation of point-to-point motions and interpolating motions
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 safety
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 circuitry
- 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 second encoder:
- For safety-related 2-channel solutions with redundant measuring system
- For greater positioning accuracy of the axis mechanism
- For special applications (e.g. flying saws)
- For synchronisation of two axes
7. Motor connection
The servo motor EMMT-AS is connected via a one-cable solution (OCP)
Other servo motors are connected with separate cables
8. DC link coupling
Feed energy back via the intermediate circuit
9. Operating panel CDSB
Control element with touchscreen and USB interface
Simple, full-text diagnostics and setting of the servo drive on site
