8.1 Troubleshooting
The following sections describe troubleshooting in response to alarm displays.
The alarm name, alarm meaning, alarm stopping method, and alarm reset capability are listed in order of the
alarm numbers in 8.1.1 List of Alarms.
The causes of alarms and troubleshooting methods are provided in 8.1.2 Troubleshooting of Alarms.
8.1.1 List of Alarms
The list of alarms is given below.
„ Alarm Stopping Method
Gr.1: The linear servomotor is stopped according to the settings in Pn001.0 if an alarm occurs. Pn001.0 is fac-
tory-set to stop the linear servomotor by applying the DB.
Gr.2: The linear servomotor is stopped according to the setting in Pn00B.1 if an alarm occurs. Pn00B.1 is fac-
tory-set to stop the linear servomotor by setting the speed reference to “ 0. ” The linear servomotor under
force control will always use the Gr.1 method to stop. By setting Pn00B.1 to 1, the linear servomotor
stops using the same method as Gr.1. When coordinating a number of linear 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.
