Fault descriptions
Table 4.A Fault types, descriptions and actions.
No. Fault Type Description Action
F2 Auxiliary input
①
Auxiliary input interlock
is open.
1. Check remote wiring.
2. Verify Communications programming
for intentional fault.
F3 Power loss
②
Excessive DC Bus
voltage ripple.
1. Monitor the incoming line for phase
loss or line imbalance.
2. Check input line fuse.
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 P109 and/or A402 [Accel time x]
or reduce load so drive output current
does not exceed the current set by
parameter A441 [Current limit].
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 P103 [Motor OL current].
2. Verify A453 [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 (104°F) for IP
30/NEMA 1/UL Type 1 installations or
50°C (122°F) for IP20/Open type
installations.
2. Check fan.
F12 HW overcurrent
②
The drive output
current has exceeded
the hardware current
limit. Check programming. Check for excess
load, improper A453 [Boost select]
setting, 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.
