z NOTE: Shaded faults are auto-resettable, except where noted.
30 Param Range
Parameter out of
range
0
One of the customer parameters
is out of range
- Reset parameters to factory
default
- Consult factory
31 Pwr Wiring Power wiring error
0
This fault ags 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 specications
- Add a transformer or reduce
demands to power feed
- Increase line capacity
- Exchange magnetic switch.
- Consult factory
33 1Ph Overload 1Ph overload 0
If the user congures parameter
AFN 28 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
35 Fan Loss
Loss of fan control or
operation
0
There is a problem with the heat
sink fan
- Consult Factory
1
There is a problem with the
internal fan. This occurs only on
Size 4 and 5 models. All other
models display a fan error
warning.
Note that this is a lack of fan
control, so the fan can be
spinning and this fault will still
occur. This can happen if the fan
is on and should not be, or if the
fan feedback signals are
obstructed from getting to the
control board.
