Loading...What to do if write parameter error occurs: read only on Delta ASD-A2-0421?
If the parameter is read only, correct the PR command and parameter setting value.
What to do if write parameter error occurs: exceeds the limit of normal range on Delta ASD-A2-0421?
If the parameter setting value exceeds the limit of normal range, correct the PR command and parameter setting value.
What to do if CANopen PDO object is read-only and write-protected on Delta Servo Drives?
If the specified object in the message is read-only and write-protected (cannot be changed), 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 ASD-A2-0421 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.
How to solve DSP firmware upgrade issue on Delta Servo Drives?
To solve a DSP firmware upgrade issue on Delta Servo Drives, set P2-08 to 30 first, and then 28 next, and restart the servo drive.
What is motor protection error on Delta ASD-A2-0421?
A motor protection error on Delta Servo Drives means that the setting value of parameter P1-57 is reached after a period of time set by parameter P1-58. Set P1-57 to 0. Correctly set P1-57 and P1-58.
What does pre-overload warning mean for Delta ASD-A2-0421 Servo Drives?
A pre-overload warning for Delta Servo Drives means that the drive is going to overload. Please refer to the correction actions of AL006. Increase the setting value of P1-56 or set P1-56 to 100 and above.
What does input power phase loss mean for Delta Servo Drives?
If your Delta Servo Drive is experiencing input power phase loss, it indicates that the control power supply is in error. If the fault persists even when the three-phase power is connected correctly, please contact your distributor or Delta for assistance.
What does it mean when my Delta Servo Drive has a memory error?
A memory error on your Delta Servo Drive can occur due to: * Parameter data error when writing into EE-PROM. If this is the case, correct the setting value of the parameter to clear the fault and restart the servo drive. * The setting value of a hidden parameter is in error. If this fault occurs when resetting the parameter settings, it indicates that the servo drive type is not set correctly. Correctly set the servo drive type again. * Data in EE-PROM is damaged. If this is the case, please contact your distributor or Delta for assistance.
What causes IGBT temperature error in Delta ASD-A2-0421?
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.
