 P600 sets the minimum voltage level at which the motor can operate
1 %Un of the Motor
without problems. This protection function acts when the line voltage
drops to a value lower than the set and is present during a time equal
1 to 99
to or longer than those set at P601. If this condition is present, the

Soft-Starter is disabled and an Undervoltage Error is displayed.

 P602 sets the maximum overvoltage level that the motor allows, during
the time that has been set at P603. If this time is exceeded, the
0 to 20
Soft-Starter is disabled and an Overvoltage Error is displayed.
