Table 4.A Fault Types, Descriptions and Actions
Fault Descriptions
No. Fault
Type
(1) Description Action
F2 Auxiliary Input ➀ Auxiliary input interlock is open. 1. Check remote wiring.
2. Verify communications
programming for intentional fault.
F3 Power Loss ➁
Excessive DC Bus voltage ripple. 1. Monitor the incoming line for
phase loss or line imbalance.
2. Check input line fuse.
F4 UnderVoltage ➀
DC bus voltage fell below the
minimum value. Monitor the incoming AC line for low
voltage or line power interruption.
F5 OverVoltage ➀ 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 ➀ 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 ➀
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 ➀ 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 ➁ 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 ➁ 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.
