Compact servodrive combines motion control and safety functions
30 January 2026 
Festo has announced a servodrive that combines motion control and safety functions in a compact device. The CMMT-AS-MP-S3 drive is designed to simplify the implementation of high-level extended safety in automated machinery.
The drive can be used to achieve safety in linear or rotational motion applications, possibly in conjunction with Festo mechanics. It is particularly suitable for demanding safety applications in assembly and handling technologies, packaging machines and the electronics industry.
“The CMMT-AS-S3 delivers the power and precision Festo customers expect, but with extended and integrated safety features,” explains Ben Lloyd, Festo’s product manager for electric automation in the UK. “We’ve packaged everything into a compact servodrive that requires no additional wiring or modules, delivering space and cost savings and reducing complexity while meeting the highest standards of functional safety.”
The drive spans ratings from 300W to 12kW. It can achieve safety levels up to PLe, SIL3, Category 3 and 4. It supports Safe Torque Off (STO), Safe Brake Control (SBC), Safe Stop 1 and 2 (SS1 and SS2) and Safe Operating Stop (SOS), as well as Safe Maximum Speed (SMS), and Safely Limited Speed (SLS).
The drive integrates with Festo’s pneumatic and electric automation products, and supports Ethernet-based fieldbuses such as EtherCat, EtherNet/IP, Profinet and ModbusTCP.
Standard safety parameters can be set without using software, but programming the drive via the Festo Automation Suite (FAS) saves time and offers guidance. An intuitive graphical interface simplifies safety set-ups, validation, commissioning, programming, diagnostics and firmware updates. FAS cuts commissioning times by offering realistic preset values and guided validation of safety functions. It also supports I/O and fieldbus configuration and the ability to generate validation reports.
