EEPROM Error

What does E08. mean?

This error indicates a problem with the inverter's built-in EEPROM, where parameters are stored. It can be caused by external electrical noise, abnormal temperature, or a corrupt memory block. This fault prevents the inverter from accepting reset commands and means stored parameters might be corrupted or unreadable, potentially leading to incorrect operation.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   If the error persists after power cycling, turn off the power supply and perform a parameter initialization to reset settings. (Note: this clears all stored parameters).

2. 4

   If the error persists after initialization, the inverter's EEPROM or main board may be faulty and require replacement.
