CPF02
A/D Conversion Error
An A/D conversion error or control circuit error occurred.
CPF03
Control Board Connection Error
Connection error between the control board and the drive
CPF06
EEPROM Memory Data Error
Error in the data saved to EEPROM
Cause Possible Solution
There is an error in EEPROM control circuit
• Turn off the power and check the connection between the control board and the drive.
• If the problem continues, replace the control board or the entire drive. Contact Yaskawa or a Yaskawa
representative for instructions on replacing the control board.
The power supply was switched off while
parameters were being saved to the drive
Reinitialize the drive (A1-03 = 2220, 3330).
