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 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.

Meaning
The data of the parameter in the SERVOPACK is incorrect.
The data of the parameter in the SERVOPACK 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 conditions.
Combination of some parameters exceeds the setting range.
The settings of the 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 servomotor capacities do not match each
other.
The servo ON command was turned ON 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.
Regenerative circuit or regenerative resistor is faulty.
Regenerative energy exceeds regenerative resistor capacity.
• Setting of AC input/DC input is incorrect.
• Power supply wiring is incorrect.
Main circuit DC voltage is excessively high.
