• Review the possible solutions provided for handling noise interference.
• Review the section on handling noise interference and check the control circuit lines, main circuit lines,
and ground wiring.
• Check if the fault occurs simultaneously with overexcitation function operation.
• Consider motor flux saturation and reduce the value of n3-13 (Overexcitation Deceleration Gain).
• Set b3-01 to 1 to enable Speed Search at Start.
• Program the Speed Search command input through one of the multi-function contact input terminals
(H1-oo = 61 or 62).
Use a larger drive.
Option Card Connection Error at Option Port CN5-A
Option compatibility error
Check if the drive supports the option card to be installed. Contact Yaskawa for assistance.
Option Card Fault at Option Port CN5-A
Option not properly connected
• Turn off the power and reconnect the option card.
• Check if the option card is properly plugged into the option port. Make sure the card is fixed properly.
• If the option is not a communication option card, try to use the card in a different option port. If the option
card works properly in a different option port, CN5-A is damaged, and the drive requires replacement. If
the error persists (oFb01 or oFC01 occur), replace the option card.
