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
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.

Alarm Name
The data of the parameter in the SERVOPACK is incorrect.
The data format of the parameter in the SERVOPACK is
incorrect.
The data of the parameter in the SERVOPACK is incorrect.
Detection data for power circuit is incorrect.
The parameter setting is outside the allowable setting range.
The encoder output resolution setting (Pn281) is outside the
allowable setting range or does not satisfy the setting condi-
tions.
Combination of some parameters exceeds the setting range.
The settings of the fully-closed option module and Pn00B.3,
Pn002.3 do not match.
There is an error in settings of parameters reserved by the
system.
The SERVOPACK and the linear servomotor capacities do
not match each other.
The unsupported device unit was connected.
The setting of the linear scale pitch (Pn282) has not been
changed from the default setting.
The Servo ON command was sent from the host controller
after the utility function was executed to turn the power to
the linear servomotor ON.
An overcurrent flowed through the IGBT.
Heat sink of the SERVOPACK was overheated.
Regenerative circuit or regenerative resistor is faulty.
Regenerative energy exceeds regenerative resistor capacity.
