Introduction TR150 and TR170 Service Manual 1.9 Ratings 1.9.1 Short Circuit and Overcurrent Trips The frequency converter is protected against short circuits with current measurement in each of the 3 motor phases or in the DC link. A short circuit between 2 output phases causes an overcurrent in the inverter. The inverter turns off the IGBTs individually when the short-circuit current exceeds the permitted value (Alarm 16 Trip Lock).
