Regen Time
Regen timeout
0
This fault occurs if the drive
takes more time to decelerate
to a stop than is allowed. The
timeout is determined by the
longest deceleration ramp time
(Decel1 or Decel2) plus the
Regen Timeout parameter.
Reduce the amount of
regenerative energy or
iincrease the Regen
timeout parameter.
27
Pwr Bridge
Power bridge
fault
0,1,2
The drive detected a failure in
the output power devices.
Check for failed input
power device.
28
Drive TOL
Drive timed
overload
0
The drive sensed an overload
that exceeded the drive rating.
Check that load
conditions do not
exceed the drive’s
rating (120% for 60
seconds from
nameplate current
rating for normal duty
and 150% or rated
current for 60 seconds
heavy duty).
29
Stuck Key
Stuck key error
0
This fault occurs if a key press
is detected upon power-up.
This would occur because of a
defective keypad or because
someone was holding down a
key when powering-up the
drive.
Check for stuck keypad
and repair or replace.
Consult factory.
30
Param Range
Parameter out
of range
0
One of the customer
parameters is out of range.
Check for a parameter
value saved out of the
standard range. Reset
parameters to factory
default. Consult
factory.
31
Pwr Wiring
Power wiring
error
0
This fault flags a problem with
the drive wiring.
Check that input power
wiring is not connected
to load power
terminals. Consult
factory.
1
This fault can occur if an IOC
fault is detected during the
power wiring test.
32
Low Voltage
Low voltage trip
0
This fault occurs if a power dip
occurs when the drive is
operating, and the drive is not
able to ride through the power
dip before shutting off outputs.
Verify that input line
power is within the
drive’s specifications.
Add a transformer or
reduce demands to
power feed. Consult
factory.
33
1Ph Overload
1Ph overload
0
If the user configures
parameter 517 (Single Phase)
for single-phase operation, this
fault occurs if the bus voltage
ripple is outside the limit of the
drive.
Check that input power
demand does not
exceed the drive’s
capacity for single-
phase operation.
Consult factory.
34
RS Meas. Fail
Stator
resistance
measurement
failed
0
If the drive cannot measure the
stator resistance properly, this
fault occurs.
Try the routine again
and if the fault occurs
twice, consult the
factory.

37
Encoder Flt
Fault in
encoder
0
Encoder overspeed fault.
Check parameters for
proper configuration.
1
The encoder has improper
setup.
Try setting up the
encoder again; consult
factory for assistance if
needed.
2 or 3
The encoder is not functioning
properly.
Consult factory.
