Code Name Causes Possible Solutions
Err EEPROM Write Error
There was a problem with the EEPROM hardware. • Re-energize the drive.
• If the fault stays, replace the control board or the drive.
Contact the manufacturer or your nearest sales representative
to replace the board.
Electrical interference corrupted the data while it
was writing to the EEPROM of the drive.
• Push ENTER Key.
• Set the parameters again.
Note:
Do a Fault Reset to clear the fault.
Code Name Causes Possible Solutions
FbH Excessive PID Feedback
The FbH detection level is set incorrectly. Adjust b5-36 [PID HiHi Limit Level] and b5-37 [PID HiHi
Time].
There is a problem with the PID feedback wiring. Correct errors with the PID control wiring.
The feedback sensor is not operating correctly. Examine the sensors on the control device side.
