• Check the various options available to minimize the effects of noise.
• Counteract noise in the control circuit, main circuit, and ground wiring.
• Ensure that other equipment such as switches or relays do not cause noise. Use surge absorbers if
necessary.
• Use only recommended cables or other shielded line. Ground the shield on the controller side or the drive
input power side.
• Separate all communication wiring from drive power lines. Install an EMC noise filter to the drive power
supply input.
Replace the option card if there are no problems with the wiring and the error continues to occur.
• The connector pins on the option card do not line up properly with the connector pins on the drive.
• Reinstall the option card.
