Control Fault
CF
The torque limit was reached continuously for three seconds after the Stop command was input and
deceleration was not possible in OLV Control.
Check the motor parameter settings and repeat Auto-Tuning.
Set the torque limit to the most appropriate setting (L7-01 through L7-04).
• Adjust the deceleration time (C1-02, C1-04, C1-06, C1-08).
• Set the frequency to the minimum value and interrupt the Run command when the drive finishes
decelerating.
Control Circuit Error
• Cycle power to 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.
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 the control board or the entire drive. Contact Yaskawa or a Yaskawa
representative for instructions on replacing the control board.
Control Board Connection Error
CPF03
Connection error between the control board and the drive
• 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.
• Check the various options available to minimize the effects of noise.
• 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 the
drive input power side.
• Ensure that other equipment such as switches or relays do not cause noise. 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
Error in the data saved to EEPROM
• 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.
Reinitialize the drive (A1-03 = 2220, 3330).
