Sets start time (start compensating time). When the motor starts, there is a possibility that the motor current will exceed the set current value, but during the start time period it will not trip. Shock Time Setting (SHOCK TIME) Sets shock time (output delay time). When the motor current exceeds the set current value the count begins, and when shock time has elapsed, it will trip.
