Adjustment
1. Calculate C0120. This value corresponds to a motor utilisation of 100 %:
I
r
C0120 [%] + @ 100 %
I
N
2. If you decrease C0120 on the basis of the value calculated, the monitoring already responds at
a motor utilisation < 100 %.
3. If you increase C0120 on the basis of the value calculated, the monitoring only responds at a
motor utilisation > 100 %.
The controller switches off with error OC6 if the apparent motor current is greater than the rated
motor current for a longer time.
