What causes overspeed in Delta ASD-A2-0721 Servo Drives?
Overspeed in Delta Servo Drives can be triggered by: * Unstable speed input command (too much fluctuation). If this is the case, ensure that input command frequency is stable (not fluctuate too much) and activate filter function. * Defective over-speed parameter setting. If this is the case, correctly set over-speed parameter setting (P2-34).
What causes undervoltage in Delta ASD-A2-0721 Servo Drives and how to fix it?
Undervoltage in Delta Servo Drives can be caused by: * The main circuit voltage being below its minimum specified value. If this is the case, reconfirm voltage wiring. * No input voltage at the main circuit. If this is the case, reconfirm the power switch. * Incorrect power input. If this is the case, use the correct power supply, a stabilizing power supply, or a series transformer.
How to fix An error occurs when loading CANopen data in Delta ASD-A2-0721 Servo Drives?
To fix an error occurs when loading CANopen data in Delta Servo Drives, when an error occurs when loading data via EEPROM, use DI.ARST, CANopen 0x1011 Restore default parameter.
What to do if CANopen PDO object does not support PDO on Delta Servo Drives?
If the specified object in the message does not support PDO, NMT Maser send “Reset node“ command to its slave or reset the fault by sending the control word (0x6040) through CAN communication (the value of CANopen object 0x6040 should be reset).
What to do if Delta Servo Drives show abnormal pulse command?
If your Delta Servo Drives are showing an abnormal pulse command, it could be because the pulse command frequency is higher than the rated input frequency. Correctly set the input pulse frequency.
How to resolve a serial communication timeout on Delta ASD-A2-0721 Servo Drives?
A serial communication timeout on Delta Servo Drives can occur if: * The setting value in the timeout parameter is not correct. If this is the case, correctly set P3-07. * Communication command is not being received for a long time. If this is the case, tighten the communication cable, make sure the communication cable is not damaged and ensure all wiring is correct.
What to do if index error occurs when accessing CANopen object on Delta Servo Drives?
If the specified Index in the message does not exist, NMT Maser send “Reset node“ command to its slave or reset the fault by sending the control word (0x6040) through CAN communication (the value of CANopen object 0x6040 should be reset).
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 fix over current in Delta ASD-A2-0721 Servo Drives?
If your Delta Servo Drive is showing an over current error, there are several potential causes and solutions: * A short circuit in the drive output: Eliminate the short circuit, ensuring no metal conductors are exposed. * Incorrect motor wiring: Rewire the motor following the wiring instructions in the user manual. * A faulty IGBT: Send the drive back to the distributors or contact Delta. * Incorrect control parameter settings: Reset to the default settings and then gradually adjust the values. * Unreasonable command: Use a less steep command or apply a filter to smooth the command.
What causes CANbus error on Delta Servo Drives?
A CANbus error on Delta Servo Drives is caused by CANbus off or Error Rx/Tx Counter exceeding 128. NMT Maser send “Reset node“ command to its slave or restart the servo drive.
