9.1
Alarm Displays
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 9.1.1 List of Alarms.
The causes of alarms and troubleshooting methods are provided in 9.1.2 Troubleshooting of Alarms.
9.1.1
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 coasts to a stop when an alarm occurs.
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.

Meaning
The data of the parameter in the SERVOPACK
is incorrect.
The data of the parameter in the SERVOPACK
is incorrect.
The data of the parameter in the SERVOPACK
is incorrect.
Detection data for main circuit is incorrect.
The parameter setting is outside the setting
range.
The encoder output pulse (Pn212) is outside the
setting range or does not satisfy the setting con-
ditions.
Combination of some parameters exceeds the
setting range.
The SERVOPACK and the servomotor capaci-
ties do not match each other.
The device unsupported was connected.
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.
Main circuit DC voltage is excessively high.
The capacitor of the main circuit has deterio-
rated or is faulty.
The servomotor speed is above the maximum
rotational speed.
