6.11.1 Slip compensation
The speed of an asynchronous machine decreases when being loaded. This
load−dependent speed drop is called slip. By setting C0021 the slip can be
partly compensated.
In the V/f characteristic control mode the slip compensation is only active at
operation without feedback (C0025 = 1).
