9 Troubleshooting9.1.1 List of Alarms9-29.1 Alarm DisplaysThe 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 thealarm 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 AlarmsThis section provides list of alarms. 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.AlarmNumber Alarm Name MeaningServo-motorStoppingMethodAlarmResetA.020 Parameter ChecksumError 1The data of the parameter in the SERVOPACK isincorrect. Gr.1 N/AA.021 Parameter Format Error 1 The data of the parameter in the SERVOPACK isincorrect. Gr.1 N/AA.022 System Checksum Error 1 The data of the parameter in the SERVOPACK isincorrect. Gr.1 N/AA.030 Main Circuit Detector Error Detection data for main circuit is incorrect. Gr.1 AvailableA.040 Parameter Setting Error 1 The parameter setting is outside the setting range. Gr.1 N/AA.041 Encoder Output PulseSetting ErrorThe encoder output pulse (Pn212) is outside the set-ting range or does not satisfy the setting conditions. Gr.1 N/AA.042 Parameter Combination Er-rorCombination of some parameters exceeds the settingrange. Gr.1 N/AA.044Semi-closed/Fully-closedLoop Control ParameterSetting ErrorThe setting in the fully-closed option module andthe setting in Pn002.3 do not match. 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 donot match each other. Gr.1 AvailableA.051 Unsupported Device Alarm The device unsupported was connected. Gr.1 N/AA.0b0 Canceled Servo ONCommand AlarmThe servo ON command (SV_ON) was sent fromthe host controller after executing a utility functionthat turns ON servomotor.Gr.1 AvailableA.100 Overcurrent or Heat SinkOverheatedAn overcurrent flowed through the IGBT or the heatsink of the SERVOPACK was overheated. Gr.1 N/AA.300 Regeneration Error Regenerative circuit or regenerative resistor isfaulty. Gr.1 AvailableA.320 Regenerative Overload Regenerative energy exceeds regenerative resistorcapacity. Gr.2 Available
