Servo Control - Siemens SINAMICS S120 Function Manual

Servo control

Function description
The servo control mode enables operation with a high dynamic response and precision for a
motor with motor encoder.
The motor connected to servo control is simulated in a vector model based on data from the
equivalent circuit diagram. Consequently, the servo control constitutes a field-oriented control.
However, for servo control, the vector model is optimized according to other criteria. In favor of
achieving a high dynamic performance, a small deterioration in the control accuracy and control
quality is taken into consideration.
Features
Special features of the servo control include:
● Maximum computing speed
● Shortest sampling times
● Maximum dynamic performance
● High output frequencies (> 800 Hz)
● Preferably used with permanent magnet synchronous motors with the appropriate dynamic
performance
