V1.25
Fault
VFD1 MCU
Watchdog fault
VFD has detected
internal processing error.
Power cycle drive. Contact Gardner Denver
service.
V1.32
Fault
VFD1 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.
V1.36
Fault
VFD1 Device
Compatibility
fault
VFD has detected and
compatibility error
between its control board
and power board.
Power cycle drive. Contact Gardner Denver
service.
V1.37
Warning
VFD1 Device
Changed
warning
VFD has detected new
option card or control
board hardware
Power cycle drive. Contact Gardner Denver
service.
V1.38
Warning
VFD1 Device
Added warning
VFD has detected a new
option card has been
installed
Power cycle drive. Contact Gardner Denver
service.
V1.39
Fault
VFD1 Device
Removed fault
VFD has detected
removal of an Option
card
Power cycle drive. Contact Gardner Denver
service.
V1.40
Fault
VFD1 Device
Unknown fault
Unknown option card or
power board connected
to control section.
Power down drive, check option card and ribbon
cable are connected. Replace option board or
drive.
V1.41
Fault
VFD1 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
motor and VFD for incorrect or loose connections.
Verify supply voltage within tolerance. Test fan
motor insulation resistance.
V1.51
Warning
VFD1 External
Input warning
VFD has detected
external fault input active
Check for any damage in external cable/wirings
and check if there is any loose connections or
terminal.
V1.51
Fault
VFD1 External
input fault
VFD has detected
external fault input active
Check for any damage in external cable/wirings
and check if there is any loose connections or
terminal.
V1.55
Warning
VFD1 Real Time
Clock warning
VFD reporting error with
the real time clock
Power cycle drive. Contact Gardner Denver
service.
V1.55
Fault
VFD1 Real Time
Clock fault
VFD reporting error with
the real time clock
Power cycle drive. Contact Gardner Denver
service.
V1.58
Fault
VFD1 Current
Measure fault
VFD has detected an
error with its internal
current measuring
devices
Power cycle drive. Contact Gardner Denver
service.
V1.59
Fault
VFD1 Power
Wiring fault
Input/Output wiring to
VFD is incorrectly
connected
Power the drive down and safely lock out system.
Inspect and verify input power wires are properly
connected to VFD terminals L1/L2/L3. Inspect
and verify motor leads are connected to the VFD
output terminals U/V/W.
V1.60
Fault
VFD1 Control
Board Over
Temp fault
VFD is measuring control
board temperatures
above the fault limit.
Confirm ambient temperature near the VFD is
below 50C. Check ventilation filters and fans
mounted in the control panel for debris. If
equipped, confirm the small control board cooling
fan is operational.
V1.61
Fault
VFD1 Internal
control power
supply fault
VFD is reporting that the
internal 24VDC control
supply outside the range
of 18-27VDC
Using a multi-meter, measure 24VDC supply at
the control board terminals. If the voltage is in
range, power cycle the drive. If out of range,
contact Gardner Denver service.
