Troubleshooting ASDA-B2-F9-10 September, 20159AL026 Unreliable internal data of the encoder Cleared after re-power onCauses Checking Method Corrective ActionsThe encoder is in error.(Errors occur in the internaldata for three timescontinuously)1. Check if the servo motor is properlygrounded.2. Check if the encoder cable isseparated from the power supply orhigh-current cable to avoidinterference.3. Check if the shielding cables areused in the wiring of the encoder.1. Please connect the UVWconnector (color green) to theheat sink of the servo drive.2. Please check if the encodercable is separated from thepower supply or thehigh-current cable.3. Please use cables withshielding mesh.4. If issue persists, please sendthe drive back to the distributorsor contact with Delta.AL027 The internal of the motor is in error Cleared after re-power onCauses Checking Method Corrective ActionsThe internal reset of theencoder is in error.1. Check if the encoder communicationcable is properly connected.2. Check if the power supply is stable.3. Check if the operation temperatureexceeds 95°C.1. Check if the encodercommunication cable isnormal.2. Please use encodercommunication cable withshielding mesh.3. If issue persists, please sendthe drive back to thedistributors or contact withDelta.AL028 Encoder voltage error or the internal ofthe encoder is in error Cleared after re-power onCauses Checking Method Corrective ActionsBattery voltage is too high. 1. Check if there is charging circuit inthe servo drive.2. Check if the battery is correctlyinstalled. (Voltage > 3.8 V)Please do the check according tothe procedure of over voltage.When corrective actions are done,AL028 will be clearedautomatically.The internal of the encoderis in error.1. Check if it is absolute encoder.2. Check if the servo motor is properlygrounded.3. Check if the encoder cable isseparated from the power supply orhigh-current cable to avoidinterference.4. Check if the shielding cables areused in the wiring of the encoder.1. If the situation is not improving,please send the drive back tothe distributors or contact withDelta.2. Please connect the UVWconnector (color green) to theheat sink of the servo drive.3. Please check if the encodercable is separated from powersupply or high-current cable.4. Please use shielding mesh. Ifthe situation is not improving,please send the drive back tothe distributors or contact withDelta.AL029 Gray code error Cleared after re-power onCauses Checking Method Corrective ActionsAbsolute position is in error. Re-power on to operate the motor andcheck if the alarm occurs again.If the alarm occurs again, pleasechange the encoder.
