Chapter 10 Troubleshooting ASDA-M10-12 Revision December, 201410.4 Causes and Corrective ActionsAlarm DisplayAL001 : OvercurrentCauses Checking Method Corrective ActionsThe drive output isshort-circuitCheck if the wiring between themotor and the drive is correct andsee if the wire is short-circuited.Eliminate short-circuit and avoidmetal conductor being exposed.The motor wiring is inerror.Check if the wiring steps arecorrect when connecting themotor to the drive.Rewiring by following the wiringdescription from the usermanual.IGBT is abnormal The temperature of the heat sinkis abnormalSend the drive back to thedistributors or contact with Delta.The control parametersetting is in error.Check if the setting valueexceeds the default settingSetting back to the defaultsetting and then gradually adjustthe value.UnreasonablecommandCheck if the command doingreasonable acceleration time.Less steep command used orfilter applying to smoothcommand.AL002 : OvervoltageCauses Checking Method Corrective ActionsThe input voltage of themain circuit is higherthan the ratedallowable voltage.Use the voltmeter to see if theinput voltage of the main circuit iswithin the rated allowable voltagevalue. (please refer to Chapter12.1)Apply to the correct powersupply or serial voltageregulator.Wrong power input(incorrect powersystem)Use the voltmeter to see if thepower system matches thespecification.Apply to the correct powersupply or serial adaptor.The hardware of theservo drive isdamaged.Use the voltmeter to see if theinput voltage of the main circuit iswithin the rated allowable voltagevalue but still shows the error.Send the drive back to thedistributors or contact with Delta.
