Fan Cooling
fault
VFD has detected an
issue with its heat sink
cooling fans
Monitor the heat sink cooling fan operation. Using
a multi-meter check for 24VDC/48VDC at the
cooling fan pins during run (dependent on VFD
size). Replace cooling fans as needed.

FV1.40
Fault
VFD Cooling
Unknown
Device fault
VFD has detected and
compatibility error
between its control board
and an option board.
Power down drive. Check option card and ribbon
cable are connected.
FV1.41
Fault
VFD Cooling
IGBT Temp fault
VFD has detected that
IGBT internal
temperatures are too
high, potentially caused
by high motor current
Check motor operating current at full load is not
exceeding nominal rating. Check wiring between
fan motor and VFD for incorrect or loose
connections. Verify supply voltage within
tolerance. Check fan wheel for proper alignment
and balance. If possible, manually spin fan wheel
and observe rotation. Test fan motor insulation
resistance.
