The drive is attempting to operate a specialized
motor or a motor larger than the maximum size
allowed
Magnetic contactor (MC) on the output side of
the drive has turned on or off
V/f setting is not operating as expected
Excessive torque compensation
Drive fails to operate properly due to noise
interference
Overexcitation gain is set too high
Run command was applied while motor was
coasting
The rated output current of the drive is too
small

• Check the motor capacity.
• Ensure that the rated capacity of the drive is greater than or equal to the capacity rating found on the
motor nameplate.
Set up the operation sequence so the MC does not trip while the drive is outputting current.
• Check the ratios between the voltage and frequency.
• Set parameters E1-04 through E1-10 appropriately.
• Lower the voltage if it is too high relative to the frequency.
• Check the amount of torque compensation.
• Reduce the torque compensation gain (C4-01) until there is no speed loss and less current.
• Review the possible solutions provided for handling noise interference.
• Review the section on handling noise interference on page
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
oFA00
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
oFA01
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.
Option Card Error Occurred at Option Port CN5-A
Option Card Connection Error (CN5-A)
Communication Option Card Connection Error (CN5-A)
• Cycle power to 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.
Option Card Fault at Option Port CN5-B
oFb00
Option compatibility error
Make sure the drive supports the option card to be installed. Contact Yaskawa for assistance.
Communication option cards are only supported by option port CN5-A. It is not possible to install more
than one communication option.
