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.
The compact and powerful CMMT-AS with multiprotocol
You can easily set the desired 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: CMMT servo drive controller – from 50 W to 12 kW
Servo drives control servo motors. Thus, they are responsible for rotary applications and, together with an axis, for linear movements in the machine. Servo drive controllers are a core technology of automation. With the CMMT family we have the full 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, for example
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
