Servo family CMMT

A family approach to servo drives provides a
comprehensive and fast to use package. Users
can commission complete drive systems of
servo drive, servo motor and mechanical system
in only three minutes.

The compact servo drive CMMT-AS is designed for
dynamic point-to-point and interpolating motion
applications typically in assembly and handling
applications for packaging machines or in the
electronics industry.
With its single, closed-loop controller concept for
Ethernet-based bus systems, the servo drive
enables the direct, virtually seamless fieldbus
integration into all major controller manufacturers’
systems. This means efficient and integration into all
application programs including controller-specific
functions, for example from Siemens, Rockwell or
Beckhoff. The auto-tuning function supports the easy
commissioning of movements and automatically
