The drive tried to adjust the current offset value

beyond the allowable range. This is due to residual

induction current in the motor (e.g., during sudden

deceleration or when coasting) when the drive

attempted to start the motor.

• Create a motor restart sequence that allows enough time for residual induction voltage to dissipate.

• Enable Speed Search at start (b3-01 = 1).

The current sensor in the drive is damaged

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

Connection error between the control board and the drive

Cause Possible Solution

There is a connection error

• 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.

Drive fails to operate properly due to noise

interference

• 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.

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 using parameter A1-03.

Terminal Board Connection Error

CPF08

Cause Possible Solution

There is a faulty connection between the terminal

board and the control board

• 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.
