Fault
Type
➊
Description
Action
F2
Auxiliary Input
1
Auxiliary input interlock is open.
1.
Check remote wiring.
2.
Verify communications.
F3
Power Loss
2
DC bus voltage remained below
85% of nominal.
1.
Monitor the incoming AC line for low voltage or line power interruption.
2.
Check input fuses.
F4
UnderVoltage
1
DC bus voltage fell below the
minimum value.
Monitor the incoming AC line for low voltage or line power interruption.
F5
OverVoltage
1
DC bus voltage exceeded
maximum value.
Monitor the AC line for high line voltage or transient conditions. Bus
overvoltage can also be caused by motor regeneration. Extend the decel time
or install dynamic brake option.
F6
Motor Stalled
1
Drive is unable to accelerate motor.
Increase Parameter 139…167 (Accel Time x) or reduce load so drive output
current does not exceed the current set by Parameter 189 (Current Limit 1).
F7
Motor Overload
1
Internal electronic overload trip
1.
An excessive motor load exists. Reduce load so drive output current
does not exceed the current set by Parameter 133 (Motor OL Current).
2.
Verify Parameter 184 (Boost Select) setting
F8
Heatsink
OvrTmp
1
Heatsink temperature exceeds a
predefined value.
1.
Check for blocked or dirty heat sink fins. Verify that ambient
temperature has not exceeded 40
°
C.
2.
Replace internal fan.
F12
HW OverCurrent
2
The drive output current has
exceeded the hardware current
limit.
Check programming. Check for excess load, improper programming of
Parameter 184 (Boost Select), DC brake volts set too high, or other causes of
excess current.
F13
Ground Fault
2
A current path to earth ground has
been detected at one or more of the
drive output terminals.
Check the motor and external wiring to the drive output terminals for a
grounded condition.
F33
Auto Rstrt Tries
Drive unsuccessfully attempted to
reset a fault and resume running
for the programmed number of
Parameter 192 (Auto Rstrt Tries).
Correct the cause of the fault and manually clear.
F38
F39
F40
Phase U to Gnd
Phase V to Gnd
Phase W to Gnd
2
A phase to ground fault has been
detected between the drive and
motor in this phase
.
1.
Check the wiring between the drive and motor.
2.
Check motor for grounded phase.
3.
Replace starter module if fault cannot be cleared.
F41
F42
F43
Phase UV Short
Phase UW Short
Phase VW Short
2
Excessive current has been
detected between these two output
terminals.
1.
Check the motor and drive output terminal wiring for a shorted
condition.
2.
Replace starter module if fault cannot be cleared.
