to
oFA30 to oFA43
Comm Option Card Connection Error (CN5-A)
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.

Option Card Fault at Option Port CN5-B
Option compatibility error
Cause Possible Solution
The option card installed into port CN5-B is
incompatible with the drive.
Check if the drive supports the option card that you are attempting to install.
The following option cards are not available for this drive:
PG-X3, PG-B3, DI-A3, AI-A3, DO-A3, AO-A3
A communication option card has been installed in
option port CN5-B.
Communication option cards are supported by option port CN5-A only. More than one comm. option cannot be installed.

Option Card Connection Error at Option Port CN5-C
Option compatibility error
Cause Possible Solution
The option card installed into port CN5-C is
incompatible with the drive.
Check if the drive supports the option card that you are attempting to instal.
The following option cards are not available for this drive:
PG-X3, PG-B3, DI-A3, AI-A3, DO-A3, AO-A3
A communication option card has been installed in
option port CN5-C.
Communication option cards are supported by option port CN5-A only. More than one comm. option cannot be installed.
Digital Operator Display 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
drive capacity (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 (C6-02).
Internal cooling fan is stopped.
• Replace the cooling fan. Refer to Cooling Fan Component Names on page 303.
• After replacing the drive, reset the cooling fan maintenance parameter (o4-03 = 0).
Digital Operator Display Fault Name
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 (C6-02).
• Reduce the load.
Digital Operator Display Fault Name
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, H3-06, or H3-10 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 C1-04).
• 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.
