Option Card Fault at Option Port CN5-C
oFC01
Option not properly connected
• Turn the power off and reconnect the option card.
• Check if the option card is properly plugged into the option port. Make sure the card is fixed properly.
• Try to use the card in a different option port (in case of a PG option, use port CN5-B). If the option
card works properly in a different option port, CN5-C is damaged, and the drive requires replacement.
If the error persists (oFA01 or oFb01 occur), replace the option card.
Option Card Fault at Option Port CN5-C
oFC02
Same type of option card is currently connected
Except for PG options, only one of each option card type can only be installed simultaneously. Make sure
only one type of option card is connected.
Install a communication option, a digital input option, or an analog input option. More than one of the
same type of card cannot be installed simultaneously.
A maximum of two PG option boards can be used simultaneously. Remove the PG option board installed
into option port CN5-A.
Option Card Error Occurred at Option Port CN5-C
• 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.
Heatsink Overheat
oH
The heatsink temperature exceeded the overheat pre-alarm level set to L8-02. The default value for L8-02
is determined by drive capacity (o2-04).
• Check the temperature surrounding the drive. Verify temperature is within drive specifications.
• Improve the air circulation within the enclosure panel.
• Install a fan or air conditioner to cool the surrounding area.
• Remove anything near the drive that might be producing excessive heat.
• Measure the output current.
• Decrease the load.
• Replace the cooling fan.
• After replacing the cooling fan, set parameter o4-03 to 0 to reset the cooling fan maintenance.
Overheat 1 (Heatsink Overheat)
oH1
The heatsink temperature exceeded the drive overheat level. Overheat level is determined by drive
capacity (o2-04).
• Check the temperature surrounding the drive.
• Improve the air circulation within the enclosure panel.
• Install a fan or air conditioner to cool the surrounding area.
• Remove anything near the drive that might be producing excessive heat.
• Measure the output current.
• Reduce the load.
