FAn
Cooling Fan Error (during backup fan selection)
A cooling fan error has been detected from the fan fault detection board (FFB) signal.

Minor Fault Output
H2-
=10
Cooling fan (backup fan) fault
• Set the cooling fan ON/OFF control selection (L8-10) to 2, and confirm
whether the error occurs again after the reset operation.
• Check whether the cooling fan is operating or not.
• Replace the cooling fan according to the user’s manual if it has come to
the end of its service life, or has failed.
Yes
Fan fault detection board fault
• Check whether an error is displayed while all the cooling fans are in
operation.
• Replace the fan fault detection board. Contact Yaskawa or your nearest
sales representative on replacing the board.

Minor Fault Name
FbH
Excessive PID Feedback
The PID feedback input is higher than the level set in b5-36 for longer than the time set in b5-37,
and b5-12 is set to 1 or 4.
Cause
Possible Solutions
Minor Fault Output
H2-
=10
Parameter settings for b5-36 and b5-37 are
incorrect.
Check parameters b5-36 and b5-37.
Yes
PID feedback wiring is faulty.
Correct the wiring.
Feedback sensor has malfunctioned.
Check the sensor and replace it if damaged.
Feedback input circuit is damaged.
Replace either the control board or the entire drive. For instructions on
replacing the control board, contact Yaskawa or your nearest sales
representative.

FbL
PID Feedback Loss
The PID feedback input was lower than the level set in b5-13 (PID Feedback Loss Detection
Level) for longer than the time set in b5-14 (PID Feedback Loss Detection Time).
Cause
Possible Solutions
Minor Fault Output
H2-
=10
Parameters settings for b5-13 and b5-14 are
incorrect.
Check parameters b5-13 and b5-14.
Yes
PID feedback wiring is faulty.
Correct the wiring.
Feedback sensor has malfunctioned.
Check the sensor and replace it if damaged.
Feedback input circuit is damaged.
Replace either the control board or the entire drive. For instructions on
replacing the control board, contact Yaskawa or your nearest sales
representative.

IOV
Input Overvoltage
The main circuit power supply voltage has exceeded the setting in L2-41 for longer than the time
set to L2-42.
Cause
Possible Solution
Minor Fault Output
H2-
=10
Excessive rise of the power supply voltage
• Determine that an appropriate power supply is in use.
• Adjust the power supply voltage of the main circuit (for example,
changing the taps of the transformer).
• Change the setting of L2-41 to appropriate value.
• If detection is faulty, replace the isolation board, which detects the
power supply voltage of the main circuit, or the control board. For
instructions on replacing the control board, contact Yaskawa or your
nearest sales representative.
