Analysis, Types, and Maintenance Solutions for Delta Inverter GFF Fault

I. Meaning and Internal Mechanism of Delta Inverter GFF Fault

When a Delta inverter reports a “GFF” fault code, it indicates a “Ground Fault” (GFF) has occurred at the output terminal. This fault typically involves issues with the output circuit, such as damage to the IGBT, a short circuit in the output, or problems with the driver circuit, particularly when using PC929 optocouplers.

II. Analysis of the GFF Fault Scenario Described

In the scenario provided, the Delta inverter reports a GFF fault immediately upon connecting the motor, but the fault disappears when the motor wires are disconnected and the inverter is started alone. This suggests that the issue lies with the motor or the connection between the motor and the inverter, rather than the inverter itself.

Possible Causes:

  1. Motor Wiring Issues:
    • Short circuit or ground fault in the motor wiring.
    • Poor connection or loose wires at the motor terminals.
  2. Motor Problems:
    • Internal short circuit or ground fault within the motor.
    • Insulation failure or damage in the motor windings.
  3. External Interference:
    • Electromagnetic interference from nearby equipment affecting the inverter’s output circuit.
  4. IGBT or Driver Circuit Damage:
    • Although less likely in this case (since the fault disappears without the motor), damage to the IGBT or driver circuit could still be a factor if there are underlying issues with the inverter’s output stage.

III. Steps for Troubleshooting and Maintenance

  1. Check Motor Wiring:
    • Ensure all motor wires are properly connected and tightened.
    • Inspect the wires for any signs of damage, wear, or short circuits.
  2. Insulation Resistance Test:
    • Perform an insulation resistance test on the motor to check for insulation failure.
  3. Disconnect and Reconnect Motor:
    • Disconnect and then reconnect the motor wires to ensure a good connection.
    • Use a multimeter to test for continuity and shorts between the motor wires and ground.
  4. Isolate the Motor:
    • Try running the inverter with a different motor (if available) to determine if the fault lies with the motor or the inverter.
  5. Check Inverter Output Circuit:
    • Inspect the inverter’s output circuit for any signs of damage, particularly around the IGBTs and driver circuitry.
    • Replace any damaged components if necessary.
  6. Consult the Manual and Technical Support:
    • Refer to the Delta Inverter manual for more detailed troubleshooting steps and fault codes.
    • Contact Delta technical support for assistance if the issue cannot be resolved.

IV. Conclusion

The GFF fault reported by the Delta inverter is likely related to the motor or its connection to the inverter. By systematically checking the motor wiring, performing insulation resistance tests, and isolating the motor, the root cause of the fault can be identified and resolved. If the fault persists, further inspection of the inverter’s output circuit may be necessary.

II. Inverter Panel Function Introduction

The operation panel of the Emerson Inverter MEV2000 series serves as the primary interface between the user and the device, featuring an LED display, function keys, and indicator lights. Users can utilize the panel to view inverter status, set operational parameters, and monitor input and output signals. The primary function keys on the panel include the program/exit key, function/data key, increase/decrease keys, and run/stop keys, which can be combined to perform various operations.

Password Setting and Removal

To protect the inverter parameters from unauthorized modification, the MEV2000 series inverters offer a password protection function. Users can set a password by configuring the FP.000 parameter. Once set, a password is required to modify parameters. If password protection needs to be removed, the following steps can be followed: first, unlock the user password using the correct password, then set the FP.001 parameter to 0, and finally reset the inverter to disable password protection.

Parameter Initialization

When users need to restore the inverter parameters to the factory settings, they can do so by configuring the FP.002 parameter. Setting FP.002 to 2 will clear all user-set parameters and restore them to the default factory settings. However, please note that this operation will not restore the motor parameters. To restore motor parameters, FP.002 should be set to 4.

III. Terminal Control for Forward and Reverse Starting and Potentiometer Speed Adjustment

Setting Parameters

To use terminal control for forward and reverse starting and potentiometer speed adjustment, the following parameters need to be configured:

    • First, confirm that the OLX2 board and STO board are correctly installed inside the inverter.
    • Inspect the connections between the boards and the inverter’s mainboard to ensure they are secure and free from looseness or detachment.
  2. Check Wiring:
    • Verify that the wiring for the OLX2 board and STO board is correct, with no misconnections or missing connections.
    • Confirm that all connection wires are securely fastened and free from shorts or opens.
  3. Restart the Inverter:
    • After confirming that the boards are installed and wired correctly, attempt to restart the inverter to see if the fault is resolved.
    • If the fault persists, further inspection of the boards for potential damage may be necessary.
  4. Replace the Boards:
    • If damage to the boards is confirmed, replace them with new OLX2 and STO boards promptly.
    • After replacing the boards, reinstall and rewire them, then try to start the inverter again.
  5. Contact After-Sales Service:
    • If the above steps fail to resolve the issue, it is recommended to contact Emerson Inverter’s after-sales service personnel for professional assistance.

er.630 fault

Fault Code Meanings and Handling Methods for Inovance Servo IS620P Series

Fault Code er.630

Meaning

The er.630 fault code indicates motor stall overtemperature protection. When the motor stalls due to excessive load or mechanical obstruction during operation, and the motor temperature rises to a certain level, the servo drive will report this fault.

Solution

  1. Check Mechanical Load: Confirm whether there is any obstruction or excessive load in the mechanical part and address it promptly.
  2. Adjust Gain Parameters: Adjust the speed loop and position loop gain parameters according to the mechanical load to prevent the motor from stalling due to excessive gain.
  3. Increase Acceleration and Deceleration Time: Increase the settings of H06-05 and H06-06 to make the motor start and stop more smoothly, reducing the possibility of stalling.
  4. Check Motor and Drive Connections: Ensure that the connections between the motor and the drive are correct to avoid stalling caused by wiring errors.
  5. Monitor Motor and Drive Status: Use the Inovance drive debugging platform to monitor the motor’s operating status and the drive’s output commands to identify any anomalies.
