Troubleshooting
The following sections describe troubleshooting in response to alarm displays.
The alarm name, alarm meaning, alarm stopping method, alarm reset capability and alarm code output 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

If an alarm occurs, the servomotor can be stopped by doing either of the following operations.
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 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
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.

setting range.
The encoder output pulse setting (pulse unit)
(Pn212) is outside the allowable setting range
or not satisfies the setting conditions.
Combination of some parameters exceeds the
setting range.
The settings of the option card and Pn00B.3,
Pn002.3 do not match.
Bank member/bank data setting is incorrect.

ities do not match each other.
The device unit unsupported was connected.
The setting of the linear scale pitch (Pn282)
has not been changed from the default setting.
The Host controller reference was sent to turn
the Servo ON after the Servo ON function was
used with the utility function.
An overcurrent flowed through the IGBT.
Heat sink of the SERVOPACK was over-
heated.
Regenerative circuit or regenerative resistor is
faulty.
