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 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 set-
ting range or does not satisfy the setting conditions.
Combination of some parameters exceeds the setting
range.
The setting in the fully-closed option module and
the setting in Pn002.3 do not match.
Bank member/bank data setting is incorrect.
The SERVOPACK and the servomotor capacities do
not match each other.
The device unsupported was connected.
The servo ON command (SV_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.
Regenerative circuit or regenerative resistor is
faulty.
Regenerative energy exceeds regenerative resistor
capacity.
