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. 

FV1.60 

Fault 

VFD Cooling 
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. 

FV1.61 

Fault 

VFD Cooling 
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. 

FV1.62 

Fault 

VFD Cooling 
Flying Start fault 

VFD has detected a 
failure during a flying 
start of the fan motor. 

Check the VFD output terminal connections to the 
motor. Check if fan wheel is freewheeling in the 
wrong direction during start. Remove ventilation 
ducting causing the reverse freewheeling. 

FV1.63 

Fault 

VFD Cooling 
Current 
Imbalance fault 

The VFD has detected 
an output phase 
imbalance of more than 
20% 

Check VFD output terminal connections to the 
motor. Check the condition of the motor leads, 
and the connections in the motor junction box. 
Measure current with a clamp on amp meter in 
each lead between the VFD & motor. Test fan 
motor insulation resistance.

Current Limit 
Warning 

VFD is actively limiting 
output current to the 
cooling fan motor, motor 
is overloaded 

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. 

FV1.68 

Warning 

VFD Cooling 
Voltage Limit 
Warning 

VFD has detected that 
the DC bus voltage has 
risen above the warning 
limit, due to motor regen 
or high input voltage 

Verify supply voltage within tolerance. Check if 
fan wheel is freewheeling when not running. Fan 
deceleration may be too fast and require 
parameter adjustment, contact Gardner Denver 
service.
