If the parameter setting value exceeds the limit of normal range, correct the PR command and parameter setting value.

What to do if write parameter error occurs: exceeds the limit of normal range on Delta Servo Drives?
If the parameter setting value exceeds the limit of normal range, correct the PR command and parameter setting value.
What to do if data range error occurs when accessing CANopen PDO object on Delta Servo Drives?
If the data in the message has exceeded the data range of the specified object, 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 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.
What to do if there is a U, V, W, GND wiring error on Delta Servo Drives?
If there is a U, V, W, GND wiring error on Delta Servo Drives, it means that the wiring connections of U, V, W (for servo motor output) and GND (for grounding) are in error. Follow the wiring steps in the user manual to reconnect the wiring and ground the servo drive and motor properly.
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).
How to fix over current in Delta ASD-A2-5523 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.
How to resolve CANopen PDO is read-only and write-protected in Delta ASD-A2-5523 Servo Drives?
To resolve CANopen PDO is read-only and write-protected in Delta Servo Drives, when the specified object in the message is write- protected, use NMT: Reset node or 0x6040.Fault Reset.
How to resolve Encoder does not complete the command which is issued by servo drive in Delta Servo Drives?
If your Delta Servo Drives are showing that the encoder does not complete the command which is issued by servo drive because servo drive has not completely written barcode into encoder or the encoder does not complete the command issued by servo drive, correct the wiring.
What causes IGBT temperature error in Delta ASD-A2-5523?
An IGBT temperature error in Delta Servo Drives can occur if: * The drive has exceeded its rated load during continuous operation. If this is the case, increase motor capacity or reduce load. * There is a short-circuit at the drive output. If this is the case, ensure all wiring is correct.
What causes excessive deviation in Delta Servo Drives?
Excessive deviation in Delta Servo Drives can be caused by: * Maximum deviation parameter setting is too small. If this is the case, increase the parameter setting value of P2-35. * Gain value is too small. If this is the case, correctly adjust gain value. * Torque limit is too low. If this is the case, correctly adjust torque limit value. * There is an overload. If this is the case, reduce external applied load or re-estimate the motor capacity.
