EEP fault in an INVT GD10 drive indicates an EEPROM Operation Fault. EEPROM (Electrically Erasable Programmable Read-Only Memory) is a type of non-volatile memory used to store the drive's configuration settings and fault history.

Common Causes of EEP Faults:

1. Power Supply Issues:

   • Interruptions in power supply during the writing or reading process can corrupt the EEPROM.
   • Voltage spikes or surges can damage the EEPROM.

2. Hardware Failure:

   • A faulty EEPROM chip can lead to data corruption or inability to retain data.
   • Issues with the microcontroller or other internal components can affect the EEPROM's operation.

3. Software Errors:

   • Bugs in the drive's firmware can cause errors during EEPROM operations.
   • Incorrect parameter settings or modifications can lead to EEPROM corruption.

Troubleshooting Steps:

1. Check Power Supply:

   • Ensure a stable and reliable power supply to the drive.
   • Use a surge protector to protect the drive from voltage spikes.

2. Reset the Drive:

   • Perform a power cycle or hard reset of the drive to clear any temporary issues.

3. Verify Parameter Settings:

   • Check the drive's parameter settings to ensure they are correct and consistent.
   • Avoid making frequent or unnecessary parameter changes.
