Regenerative unit 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 regenerative unit 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 regenerative unit power lines. Install an EMC noise
filter to the regenerative unit power supply input.

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 regenerative unit.
If the problem continues, replace the control board or the entire regenerative unit. 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
regenerative unit.
Reinitialize the regenerative unit (A1-03 = 2220, 3330).
