10 Inspection, Maintenance, and Troubleshooting10.1.6 Troubleshooting of Alarm and Warning(2) Warning Display and TroubleshootingTable 10.7 Warning Display and TroubleshootingWarning Warning NameDisplayA.91 Overload:Warning for thealarms A71 andA72In either of the followingcases:1. 20% of the overloaddetection levelof A712. 20% of the overloaddetection levelof A72.A.92 RegenerativeOverload:Warning for thealarm A320A.93 Absolute EncoderBattery Warning(The battery voltagestays below thespecified value 4seconds after thecontrol power supplywas turned ON.)(Only when anabsolute encoder isconnected.)Situation at WarningOccurrenceOccurs when the servowas ON.The servomotor did notrun with a referenceinput.Occurred during normaloperation.Occurred when the controlpower supply wasturned ON.Occurred during normaloperation(Large increase ofregenerative resistortemperature.)Occurred during normaloperation(Small increase ofregenerative resistortemperature).Occurred at servomotordeceleration.Occurred when the controlpower supply wasturned ON(Setting: Pn002.2=1).Occurred 4 seconds ormore after the controlpower supply wasturned ON(Setting: Pn002.2=0).When an absoluteencoder was used.CauseWiring is incorrect and the contact in servomotorwiring is faulty.Wiring is incorrect and the contact in encoderwiring is faulty.A SERVOPACK fault occurred.Servomotor wiring is incorrect and the contact isfaulty.Encoder wiring is incorrect and the contact isfaulty.The starting torque exceeds the maximum torque.A SERVOPACK fault occurred.Corrective ActionsCorrect the servomotor wiring.Correct the encoder wiring.Replace the SERVOPACK.Correct the servomotor wiring.Correct the encoder wiring.Reconsider the load and operation conditions.Or, check the servomotor capacity.Replace the SERVOPACK.The effective torque exceeds the rated torque. Reconsider the load and operation conditions.Or, check the servomotor capacity.Temperature in the SERVOPACK panel is high. Reduce the in-panel temperature to 55°Cor less.A SERVOPACK fault occurred.Replace the SERVOPACK.A SERVOPACK fault occurred.Regenerative energy is excessive.Regenerative status continues.The setting of parameter Pn600 is smaller thanthe external regenerative resistor capacity.A SERVOPACK fault occurred.Regenerative energy is excessive.A SERVOPACK board fault occurred. (The absoluteencoder is used in the incremental encodersetting.)The battery connection is incorrect or faulty.The battery voltage is lower than the specifiedvalue 2.7 V.A SERVOPACK board fault occurred.Replace the SERVOPACK.Check the regenerative resistor capacity,or reconsider the load and operation conditions.Correct the setting of parameter Pn600.Replace the SERVOPACK.Check the regenerative resistor capacity,or reconsider the load and operation conditions.Replace the SERVOPACK.Connect correctly the battery.Replace the battery, and turn OFF theencoder power supply and ON again.Replace the SERVOPACK.10-16
