Option Card Fault at Option Port CN5-A
Option not properly connected
Cause Possible Solution
The option card connection to port CN5-A is
faulty
• 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.

Heatsink Overheat
The heatsink temperature exceeded the overheat pre-alarm level set to L8-02. The default value for L8-02
is determined by drive model selection (o2-04).
Cause Possible Solution
Surrounding temperature is too high
• 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.
Load is too heavy
• Measure the output current.
• Decrease the load.
• Lower the carrier frequency selection (C6-02).
