10.1 Alarm Displays
The following sections describe troubleshooting in response to alarm displays.
The alarm name, alarm meaning, alarm stopping method, alarm code output, and alarm reset capability are
listed in order of the alarm numbers in 10.1.1 List of Alarms.
The causes of alarms and troubleshooting methods are provided in 10.1.2 Troubleshooting of Alarms.
10.1.1 List of Alarms
This section provides list of alarms.
Servomotor Stopping Method
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 setting 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 stopping method to prevent
machine damage that may result due to differences in the stop method.
Alarm Reset
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.

The parameter setting is outside the setting
range.
The encoder output pulse (Pn212) is out-
side the setting range or does not satisfy
the setting conditions.
Combination of some parameters exceeds
the setting range.
The settings of the option module and
Pn00B.3, Pn002.3 do not match.
The SERVOPACK and the servomotor
capacities do not match each other.
The servo ON signal (/S-ON) was sent
from the host controller after executing a
utility function that turns ON servomotor.
An overcurrent flowed through the IGBT
or the heat sink of the SERVOPACK was
overheated.
