Function overview

Motors
4.1.1
Synchronous servo motors
In a typical application, permanently excited synchronous machines with sinewave EMC
sequences are used. The CMMP-AS servo positioning controller is a universal servo drive
controller that can be operated with standard servo motors. The motor data is determined
and parameterised via automatic motor identification.
4.1.2
Linear motors
In addition to rotary applications, the CMMP-AS servo positioning controller is also suitable
for use with linear motors. Permanently excited synchronous linear motors are supported.
The high quality signal processing, especially of the encoder signals, and the high clock
frequency make the CMMP-AS family of servo positioning controllers suitable for control-
ling non-ferrous and iron-core synchronous motors with low motor inductance (2 … 4mH).

Compatibility
From the user point of view, for reasons of compatibility the control structure of the CMMP-
AS servo positioning controller has largely the same properties, interfaces and parameters
as the previous SEC-AC family.
