Fault Name
Connection error between the control board and the converter
Turn off the power and check the connection between the control board and the converter.
• If the problem continues, replace the control board or the entire converter. 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 converter 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 converter power lines. Install an EMC noise filter to
the converter power supply input.
Fault Name
Error in the data saved to EEPROM
Data Error
Turn off the power and check the connection between the control board and the converter.
• If the problem continues, replace the control board or the entire converter. Contact Yaskawa or
