7.3.4 Slip compensaon
Slip compensaon serves to automacally compensate for a load-dependent speed loss.
Precondions
In order that the slip compensaon can determine the rated slip correctly, the following
parameters mus
t be set correctly:
•
Rated speed
•
Rated frequency
•
Number of pole pairs (automacally calculated from Rated speed and Rated frequency)
