13-4 HIWIN MIKROSYSTEM CORP.
13.2 Alarm
13.2.1 Alarm list
The alarms of the servo drive are listed in table 13.2.1.1. If an alarm occurs, perform troubleshooting by
referring to the alarm contents. Alarm type is used to distinguish the stopping method of motor when an
alarm occurs. The stopping method varies with different alarm types. For more information of the stopping
method of motor, please refer to section 6.9.2. To check if an alarm can be cleared by alarm reset input
(ALM-RST) signal, please refer to Alarm Reset column of table 13.2.1.1.
