Control Circuit Error
<1>
• Cycle power to the drive.
• If the problem continues, replace either the control board or the entire drive. For instructions on replacing the control board,
contact YASKAWA or your nearest sales representative.
Replace the operator.
A/D Conversion Error
CPF02
An A/D conversion error or control circuit error occurred.
• Cycle power to the drive.
• If the problem continues, replace either the control board or the entire drive. For instructions on replacing the control board,
contact YASKAWA or your nearest sales representative.
Control Board Connection Error
CPF03
Connection error between the control board and the drive
• Turn the power off and check the connection between the control board and the drive.
• If the problem continues, replace either the control board or the entire drive.
• Check the various options available to minimize the effects of noise.
• Take steps to counteract noise in the control circuit, main circuit, and ground wiring.
• Use only recommended cables or other shielded line. Ground the shield on the controller side or on the drive input power side.
• Ensure that other equipment such as switches or relays do not cause noise and use surge suppressors if required.
• Separate all communication wiring from drive power lines. Install an EMC noise filter to the drive power supply input.
EEPROM Memory Data Error
CPF06
There is an error in the data saved to EEPROM.
• Turn the power off and check the connection between the control board and the drive.
• If the problem continues, replace either the control board or the entire drive. For instructions on replacing the control board,
contact YASKAWA or your nearest sales representative.
Reinitialize the drive (A1-03 = 2220, 3330).
CPF07
Terminal Board Connection Error
CPF08
• Turn the power off and reconnect the terminal board.
• If the problem continues, replace either the control board or the entire drive. For instructions on replacing the control board,
contact YASKAWA or your nearest sales representative.
