Description Action
F2 Auxiliary
Input Y Auxiliary input interlock
is open.
• Check remote wiring.
• Verify communications
programming for
intentional fault.
F3 Power Loss N DC bus voltage
remained below 85%
of nominal.
• Monitor the incoming
AC line for low voltage
or line power
interruption.
• Check input fuses.
F4 UnderVoltage Y DC bus voltage fell
below the minimum
value.
Monitor the incoming AC
line for low voltage or line
power interruption.
F5 OverVoltage Y 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 Y Drive is unable to
accelerate motor.
Increase Accel Time x
(P039, A067) or reduce
load so drive output
current does not exceed
the current set by
parameter A089 (Current
Limit 1).
F7 Motor
Overload Y Internal electronic
overload trip.
• An excessive motor load
exists. Reduce load so
drive output current
does not exceed the
current set by parameter
P033 (Motor OL
Current).
• Verify Boost Select
(A084) setting.
