If your Delta Servo Drives are showing that the internal of the encoder is in error:* The internal of the encoder is in error. (The internal memory and the internal counter are in error): If issue persists, please send the drive back to the distributors or contact with Delta.* When power on, the motor operates because of mechanical inertia or other causes: When power on, please make sure the motor shaft stands still and will not operate.
What causes abnormal EEPROM in Delta ASD-A2-0721 Servo Drives?
If your Delta Servo Drives are showing an abnormal EEPROM:* It is in error when DSP accesses EEPROM: The fault occurs when applying to the power. It means one of the parameters is over the reasonable range. Please re-power on after adjusting. The fault occurs in normal operation. It means it is in error when writing the parameter. The alarm can be cleared by DI.ARST.* Abnormal hidden parameter: Please set the correct type of the drive.* Data in ROM is damaged: Please send the drive back to the distributors or contact with Delta.
What causes Abnormal Signal Output in Delta ASD-A2-0721 Servo Drives?
If your Delta Servo Drives are showing abnormal signal output:* The encoder is in error and cause the abnormal signal output: Conduct the corrective actions of AL.011, AL.024, AL.025, AL.026.* The output pulse exceeds the hardware allowable range: Correctly set parameter P1-76 and P1-46.
What to do if Delta Servo Drives show Encoder voltage error or the internal of the encoder is in error?
If your Delta Servo Drives are showing encoder voltage error or the internal of the encoder is in error:* Battery voltage is too high: According to the procedure of Over voltage to check. When corrective actions are done, AL.028 will be cleared automatically.* The internal encoder is in error: If the situation is not improving, please send the drive back to the distributors or contact with Delta.
How to troubleshoot serial communication error in Delta ASD-A2-0721 Servo Drives?
If you're experiencing a serial communication error with your Delta Servo Drives, check the following:* Improper setting of the communication parameter: Correctly set the parameter value.* Incorrect communication address: Correctly set the communication address.* Incorrect communication value: Correctly set the value.
What causes serial communication time out in Delta ASD-A2-0721 Servo Drives?
A serial communication timeout error in Delta Servo Drives can occur due to:* Improper setting of the time-out parameter: Correctly set the value.* The drive hasn’t received the communication command for a long time: Correct wiring.
What does main circuit power lack phase mean for Delta Servo Drives?
If your Delta Servo Drives are showing main circuit power lack phase, the main circuit power is abnormal. Make sure it applies to the power. If issue persists, please send the drive back to the distributors or contact with Delta.
How to fix incorrect wiring of the motor power line U, V, W in Delta Servo Drives?
If your Delta Servo Drives are showing incorrect wiring of the motor power line U, V, W because the wiring of U, V, W of the motor is incorrectly connected or the connection is breakdown, follow the user manual to correctly wire U, V, and W and make sure it is grounded.
