Page 17: Alarms
Alarms 7 Alarms When the protective function is actuated and an alarm generates, the ALARM-OUT output will turn OFF. The motor coasts to a stop and once the motor has stopped, the motor output shaft becomes free. At the same time, the ALARM LED will start blinking. The cause of the alarm can be checked by counting the number of times the ALARM LED blinks. -
