Setting The Pid Controller - Siemens SINAMICS V20 Operating Instructions Manual

5.6.2.4

Setting the PID controller

Functionality
The integrated PID controller (technology controller) supports all kinds of simple process
control tasks, e.g. controlling pressures, levels, or flowrates. The PID controller specifies the
speed setpoint of the motor in such a way that the process variable to be controlled
corresponds to its setpoint.
