5093 Rating ID Mismatch Fault in ABB ACS380 Drive

5093 Rating ID Mismatch in the ABB ACS380 Drive indicates that the hardware identification (Rating ID) of the drive does not match the information stored in the control unit memory. During startup, the ACS380 verifies that the installed hardware matches the stored configuration. If a mismatch is detected, the drive generates Fault 5093 to prevent operation with incompatible hardware or configuration data.

This fault generally indicates a problem with the stored hardware information, firmware compatibility, control memory, or internal hardware, rather than a motor or application fault.

Possible Causes

• Hardware configuration does not match the stored Rating ID.
• Firmware update changed the stored hardware information.
• Incomplete or interrupted firmware update.
• Corrupted control unit memory.
• Incompatible control board firmware.
• Incorrect memory data.
• Replacement of internal hardware without updating configuration.
• Defective control board.
• Faulty internal memory device.
• Internal hardware communication error.
• Corrupted firmware.
• Internal PCB fault.
• Power interruption during firmware update.
• Internal drive hardware failure.

Solutions

• Cycle power to the drive.
• Repeat the power cycle if necessary.
• Verify that the firmware update completed successfully.
• Check whether the installed firmware is compatible with the drive hardware.
• Inspect the control board for signs of damage.
• Verify that all internal hardware is correctly installed.
• Reload or update the firmware if recommended by ABB.
• Restore the correct drive configuration if available.
• Replace the control board if it is defective.
• Repair or replace the drive if the fault cannot be cleared.
• Contact ABB technical support if the fault persists.

Additional Information

The ABB ACS380 Drive stores a unique Rating ID that identifies the installed hardware configuration.

During every startup, the control unit compares the stored Rating ID with the actual hardware installed in the drive.

Fault 5093 is generated when:

• The stored Rating ID does not match the detected hardware.
• The stored hardware information becomes corrupted.
• A firmware update changes or corrupts the stored configuration.
• Internal hardware has been replaced without matching configuration data.

According to ABB, this fault commonly occurs after a firmware update.

The recommended corrective actions are:

• Cycle power to the drive.
• Repeat the power cycle if necessary.
• If the fault remains, the drive may require repair or replacement.

Unlike a communication or motor fault, 5093 Rating ID Mismatch is an internal hardware/configuration verification fault that prevents the drive from operating with inconsistent hardware information.

Common Symptoms

• Drive trips with 5093 Rating ID Mismatch.
• Fault appears immediately after power-up.
• Fault occurs after a firmware update.
• Drive cannot start the motor.
• Drive remains in fault state after reset.
• Normal parameter changes do not clear the fault.
• Fault may appear after replacing internal components.
• Firmware update appears successful, but the drive will not operate.
• Repeated power cycling may clear the fault in some cases.
• Persistent fault usually indicates internal hardware or memory problems.

Recommended Troubleshooting Sequence

1. Cycle power to the drive.
2. Repeat the power cycle if required.
3. Verify whether the fault clears.
4. Check if the fault occurred after a firmware update.
5. Verify the installed firmware version is compatible with the drive.
6. Inspect the control board for visible damage.
7. Verify all internal hardware connections.
8. Reload or reinstall firmware if recommended by ABB.
9. Restore the correct hardware configuration if applicable.
10. Replace the control board if defective.
11. Repair or replace the drive if necessary.
12. Contact ABB technical support if the fault persists.

Preventive Maintenance Tips

• Use only ABB-approved firmware versions for the specific ACS380 model.
• Do not interrupt power during firmware updates.
• Verify firmware compatibility before performing updates.
• Back up drive parameters before updating firmware.
• Avoid replacing internal hardware without following ABB service procedures.
• Inspect the control board periodically for signs of damage.
• Maintain a stable power supply during firmware upgrades.
• Use only ABB-approved replacement components.
• Keep records of firmware updates and hardware replacements.
• Record recurring 5093 Rating ID Mismatch faults to assist long-term diagnostics.

Proper verification of the drive firmware, stored Rating ID, control board, internal hardware configuration, and memory integrity, along with careful firmware update procedures and the use of ABB-approved replacement components, will help prevent recurring 5093 Rating ID Mismatch faults in ABB ACS380 drives, ensuring correct hardware recognition, reliable startup, and dependable long-term operation of the drive system.
