9.1 Troubleshooting
When an alarm has been detected, the SERVOPACK stops the servomotor, and suspends motor operation.
When the SERVOPACK detects an alarm, the motor is stopped in accordance with the “alarm stopping
method” described below, and the alarm status is displayed.
 Status Displays
 Alarm Stopping Method
Gr.1: The servomotor is stopped according to the settings in Pn001.0 if an alarm occurs. Pn001.0 is factory-set
to stop the servomotor by applying the dynamic brake (DB).
Gr.2: The servomotor is stopped according to the setting in Pn00B.1 if an alarm occurs. Pn00B.1 is factory-set
to stop the servomotor by setting the speed reference to
“0.” The servomotor under torque control will
always use the Gr.1 method to stop. By setting Pn00B.1 to 1, the servomotor stops using the same
method as Gr.1. When coordinating a number of servomotors, use this alarm stop method to prevent
machine damage that may result due to differences in the stop method.
 Alarm Reset Capability
Available: Removing the cause of alarm and then executing the alarm reset can clear the alarm.
N/A: Executing the alarm reset cannot clear the alarm.
