8 Troubleshooting8.1.1 List of Alarms8-28.1 Alarm DisplaysIf an error occurs in the SERVOPACK, an alarm number will be displayed on the panel display. However, if- appears on the panel display, the display will indicate a SERVOPACK system error. Replace theSERVOPACK.This section provides a list of the alarms that may occur and the causes of and corrections for those alarms.8.1.1 List of AlarmsThis section provides a list of alarm names, alarm meanings, stopping methods, and alarm reset capabilities inorder of the alarm numbers.The multi-winding drive unit manages all of the alarms and parameters. Check them in the multi-windingdrive unit.To output specific alarms, use the ALM output in the I/O connector (CN1) on the multi-winding drive unit. Servomotor Stopping MethodIf 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-setto 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-setto stop the servomotor by setting the speed reference to "0. " The servomotor under torque control willalways use the Gr.1 method to stop. By setting Pn00B.1 to 1, the servomotor stops using the samemethod as Gr.1. When coordinating a number of servomotors, use this stopping method to preventmachine damage that may result due to differences in the stop method. Alarm ResetAvailable: 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.Example: If an A.020 alarm occurs,“020” will flash on the display.AlarmNumber Alarm Name MeaningServomotorStoppingMethodAlarmResetA.020 Parameter ChecksumError 1 The data of the internal parameter is incorrect. Gr.1 N/AA.021 Parameter Format Error 1 The data type of the internal parameter is incorrect. Gr.1 N/AA.022 System Checksum Error 1 The data of the internal parameter is incorrect.

Gr.1 N/AA.041 Encoder Output PulseSetting ErrorThe encoder output pulse (Pn212) is outside the setting range ordoes not satisfy the setting conditions. Gr.1 N/AA.042 Parameter CombinationError Combination of some parameters exceeds the setting range. Gr.1 N/AA.045 Multi-winding Drive UnitParameter Setting Error The connected SERVOPACK is not recognized. Gr.1 N/AA.04A Parameter Setting Error 2 Bank member/bank data setting is incorrect. Gr.1 N/AA.050 Combination Error The SERVOPACK and the servomotor capacities do not match eachother. Gr.1 AvailableA.051 Unsupported Device Alarm The device unsupported was connected. Gr.1 N/AA.0b0 Cancelled Servo ONCommand AlarmThe servo ON command (SV_ON) was sent from the host control-ler after executing a utility function that turns ON servomotor. Gr.1 Available
