END fault in an INVT GD10 drive typically indicates that the drive has reached its end-of-life or a predefined time limit.

Common Causes of END Faults:

1. Time-Based Limitation:

   • The drive may have a built-in time limit, after which it will trigger an END fault.
   • This limit is often set by the manufacturer to ensure the reliability and safety of the drive.

2. Internal Component Wear:

   • Over time, internal components like capacitors, power modules, or the control board may degrade, leading to performance issues and eventually an END fault.

3. Software or Firmware Issues:

   • Software or firmware bugs or corruption can cause unexpected behavior and trigger the END fault.

Troubleshooting Steps:

1. Check the Drive's Time Limit:

   • Consult the drive's manual to determine if there is a built-in time limit.
   • If the limit has been reached, you may need to replace the drive.

2. Inspect Internal Components:

   • Visually inspect the drive for any signs of damage, overheating, or loose connections.
   • Consult a qualified technician for a more thorough inspection.

3. Update Firmware:

   • If available, update the drive's firmware to the latest version to address potential bugs and improve performance.
