F2
Auxiliary Input
Auxiliary input interlock is open.
• Check the remote wiring.
• Verify communications programming
for intentional fault.
F3
Power Loss
Excessive DC Bus voltage ripple.
• Monitor the incoming line for phase
loss or line imbalance.
• Check the input line fuse.
F4
Undervoltage
DC bus voltage fell below the
minimum value.
Monitor the incoming AC line for low
voltage or line power interruption.
F5
Overvoltage
DC bus voltage exceeded the
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
install a dynamic brake option.
F6
Motor Stalled
The drive is unable to accelerate
the motor.
Increase P109 and/or A402 (accel time)
or reduce the load so the drive output
current does not exceed the current set
by the Current Limit parameter (A441).
F7
Motor Overload
Internal electronic overload trip.
• An excessive motor load exists.
Reduce the load so the drive output
current does not exceed the current
set by the Motor OL Current parameter
(P103).
• Verify the Boost Select setting (A453).
F8
Heatsink
Overtemperature
Heatsink temperature exceeds a
predefined value.
• Check for blocked or dirty heat
sink fins. Verify that the ambient
temperature has not exceeded 40° C
(104° F) for IP 30/NEMA 1/UL Type
1 installations or 50° C (122° F) for
IP10/Open type installations.
• Check the fan.
F12
HW Overcurrent
(300%)
The drive output current has
exceeded the hardware current
limit.
Check the programming. Check for
excess load, an improper Boost Select
setting (A453), DC brake volts set too
high, or other causes of excess current.
F13
Ground Fault
A current path to the 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 Restart Tries
The drive unsuccessfully
attempted to reset a fault
and resume running for the
programmed number of auto
restart tries (A451).
Correct the cause of the fault and
manually clear.
