Description / Notes
The under and overvoltage are setting as percentage of the motor
rated voltage (P400).
P600 sets the minimum voltage level at which the motor can operate
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
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
Soft-Starter is disabled and an Overvoltage Error is displayed.
NOTE!
These functions are active the entire time the motor is running.
