EA180 Series Servo Drive Users Manual 103 Al01B : Mismatch between drive and motor Alarm Scenarios Inspection Troubleshooting Drive does not match the motor 1: Check if the voltage level of the motor is consistent with that of the drive 2: Check if the motor code in the drive is consistent with that on the motor nameplate 1: Match drive and motor correctly 2: Enter the motor code correctly Al01C : Homing failed Alarm Scenarios Inspection Troubleshooting Pb-00 parameter is set too small Check whether the set value of Pb-00 is appropriate Increase the value of Pb-00 External detector or limit switch failure Check external detectors, limit switches and wires Remove the fault Al01d :
Main power supply failure Alarm Scenarios Inspection Troubleshooting The power supply of the main circuit is cut off. Check whether the power supply logic is correct Adjust the power supply logic or maintain the status when it is really necessary to cut off the power supply to the main circuit. Al01F : System restart Alarm Scenarios Inspection Troubleshooting After some operations are completed, the drive needs to be restarted N/A Turn off the drive and power it on again Al027 : UVW shorted to ground alarm Alarm Scenarios Inspection Troubleshooting Motor lead UVW shorted to ground Check motor leads and connectors Handle the insulation problem well.
Insulation damage of internal wire package occurred in motor Check the insulation of motor windings Send it to the distributor or the manufacturer for overhaul. Al028 : Inertia identification failed Alarm Scenarios Inspection Troubleshooting Excessive load inertia Check if the load inertia is too large Reduce the load inertia or replace with a motor with a larger inertia. Abnormal mechanical connection between load and motor Check if the load is connected correctly to the motor Remove mechanical problems The number of turns that the motor can run is too small.
Check if the number of turns the motor can rotate is greater than the set value of P8-03 Adjust P8-03 parameter Appropriately increase the set value of P8-02 P8-03 is set small Check if the motor can rotate more turns Al032 : Electronic gear ratio setting range error Alarm Scenarios Inspection Troubleshooting Unreasonable setting of electronic gear ratio Check whether the setting values of the parameters related to the electronic gear ratio are appropriate. Adjust the parameters Al033 :
Input pulse frequency is too high Alarm Scenarios Inspection Troubleshooting Input pulse frequency exceeds 1MHz Check if the input pulse frequency is too high Adjust the output of the upper device Check if there is serious interference Send pulse signals using qualified twisted pair shielded conductors
