Fault Name
oFC02
Option Card Fault at Option Port CN5-C
Same type of option card already connected
Cause
Possible Solution
An option card of the same type is already installed in
option port CN5-A or CN5-B.
Except for PG options, each option card type can only be installed once. Make sure only one type of option card is connected.
An input option card is already installed in option port
CN5-A or CN5-B.
Make sure that a comm. option, a digital input option, or an analog input option is installed. The same type of card cannot be
installed twice.
Three PG option boards are installed.
Maximum two PG option boards can be used at the same time. Remove the PG option board installed into option port CN5-A.

to
oFC12 to oFC17
Cause
Possible Solution
Option card or hardware is damaged.
• Cycle power to the drive.
• If the problem continues, replace either the control board or the entire drive. For instructions on replacing the control board,
contact Yaskawa or your nearest sales representative.

Fault Name
oH
Heatsink Overheat
The temperature of the heatsink exceeded the overheat pre-alarm level set to L8-02. Default value for L8-02 is determined by the
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).
Internal cooling fan is stopped.
• Replace the cooling fan.
Refer to Cooling Fan Component Names on page 399
• After replacing the drive, reset the cooling fan maintenance parameter (o4-03 = 0).

oH1
Overheat 1 (Heatsink Overheat)
The temperature of the heatsink exceeded the drive overheat level. The overheat level is determined by drive capacity (o2-04).
Cause
Possible Solution
Surrounding temperature is too high.
• 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.
Load is too heavy.
• Measure the output current.
• Lower the carrier frequency selection (C6-02).
• Reduce the load.

oH3
Motor Overheat Alarm (PTC Input)
• The motor overheat signal to analog input terminal A1, A2, or A3 exceeded the alarm detection level.
• Detection requires multi-function analog input H3-02, H3-10, or H3-06 be set to “E”.
Cause
Possible Solution
Motor has overheated
• Check the size of the load, the accel/decel times, and the cycle times.
• Decrease the load.
• Increase the acceleration and deceleration times (C1-01 through C1-08).
• Adjust the preset V/f pattern (E1-04 through E1-10). This will mainly involve reducing E1-08 and E1-10.
• Be careful not to lower E1-08 and E1-10 too much, as this reduces load tolerance at low speeds.
• Check the motor rated current.
• Enter the motor rated current as indicated on the motor nameplate (E2-01).
• Ensure the motor cooling system is operating normally.
• Repair or replace the motor cooling system.
