FAULT
DESCRIPTION
TYPE
Drive has detected too high a
current in the motor cable:
• sudden heavy load increase
Overcurrent
• short circuit in the motor
cables
• unsuitable motor
The DC-link voltage has
exceeded the defined limits.
See Eaton User Manual for
Overvoltage LCX9000 VFD.
• too short a deceleration time
• high overvoltage spikes in
supply
Current measurement has
detected that the sum of
Ground motor phase currents is not
Fault* zero.
• insulation failure in cables or
motor
The charging switch is open,
when the START command

has been given.
Switch
• faulty operation
• component failure
Emergency Stop signal has been given
stop from the option board.
Various causes:
Saturation • component failure
trip • brake resistor short circuit or
overload
• component failure
• faulty operation
System fault Note: exceptional fault data
record, see Eaton User Man-
ual for LCX9000 VFD.
DC-link voltage is under the
defined voltage limits. See
Eaton User Manual for
Under-
LCX9000 VFD.

over 185°F (85°C). Overtem-
perature warning is issued
when the board temperature
exceeds 158°F (70°C).
Motor Motor stall protection has
stalled* tripped.
SOLUTION
Check loading. Check motor.
Check cables.
Set the deceleration time
longer.
Check motor cables and
motor.
Reset the fault and restart.
Should the fault re-occur, con-
tact Eaton.
Cannot be reset from the key-
pad. Switch off power.
If this fault appears simultane-
ously with Fault 1, check
motor cables and motor.
Reset the fault and restart.
In case of temporary supply
voltage break, reset the fault
and restart the drive. Check
the supply voltage. If it is ade-
quate, an internal failure has
occurred.
Contact Eaton.
Check supply voltage and
cable.
Check motor cable and motor.
Check brake resistor.
Check the coolant flow and
temperature.
Check motor.

CORRECTIVE ACTION
Check VFD configurations. Alarm
occurs if phase current exceeds 106%
of configured motor amps. Check cur-
rent imbalance, check entering con-
denser water temperature and water
flow rates. Verify settings in VFD_-
CONF (PIC III) / CFGUMVFD(PIC 6)
Monitor the AC line for high line volt-
age or transient conditions. Bus over-
voltage can also be caused by motor
regeneration. Extend the decel time.
Check the motor and external wiring
to the drive output terminals for a
grounded condition.
Check option board.
DO NOT RE-CONNECT POWER!
Contact Eaton.
Should the fault reoccur, contact
Eaton.
Monitor the incoming AC line for low
voltage or line power interruption. If
voltage is adequate an internal failure
has occurred.
Disable Single Cycle Dropout in
VFD_CONF (PIC III)/CFGUM-
VFD(PIC 6). Check phase-to-phase
and phase-to-ground power distribu-
tion bus voltage. Check Line Current
% imbalance in VFD_CONF (PIC III)/
CFGUMVFD (PIC 6) screen. Consult
power company.
Check motor cable and motor. Check
motor current % Imbalance in VFD_-
CONF (PIC III)/CFGUMVFD (PIC 6)
screen.
If the resistor is okay, the chopper is
faulty. Contact Eaton.
Check the ambient temperature.
Make sure that the switching fre-
quency is not too high in relation to
ambient temperature and motor load.
Circulation of air in the drive is
blocked. The cooling fans are defec-
tive.
Check VFD_HIST (PIC III) or Alarm
History (PIC 6).
