Appendix B — Fault and Warning Codes
The faults with one asterisk are "Fault" only. The faults with two asterisks can be
programmed for different actions based on the chosen application. See the appropriate
application manual for specific application details.
Table B-1: Fault Codes

Code Fault
1 Overcurrent
2 Overvoltage
3** Ground (Earth)
Fault
5 Charging Switch
6 Emergency stop
7 Saturation trip
8 System fault
MN04001004E
Possible Cause
The SVX9000/SPX9000 has detected
a high current (>4xI ) in its output
n
due to:
• sudden heavy load increase
• short in the motor
• short in the cables to the motor
• unsuitable motor
The DC-link voltage has exceeded its
high limit due to:
• too short a deceleration time
• high voltage levels or surges in
the utility supply
Current sensing indicates that the
sum of motor phase currents is not
zero.
• insulation failure in motor or
motor cables
The charging switch was open when
the START command was been given
due to:
• faulty operation
• component failure
An Emergency stop signal was
received from one of the digital
inputs
• defective component
• motor or motor cable short
• component failure
• faulty operation
Note: exceptional fault data record,
see the Active Fault Menu and Fault
Time Data Record for more

Solution
Check loading.
Check motor.
Check cables.
Make the deceleration time longer.
Use a chopper and brake resistor
(standard on some models, available
as an option on others).
Correct utility supply voltage (level is
too high).
Add input impedance to limit surges.
Check the motor and motor cables.
Reset the fault and restart.
Should the fault re-occur, contact
your Cutler-Hammer distributor.
Determine the reason for the
Emergency stop and remedy it.
Cannot be reset from the keypad.
Switch off power.
If this fault appears simultaneously
with Fault 1, check the motor and
motor cables.
IF THE PROBLEM IS NOT IN THE
MOTOR OR ITS CABLES, DO NOT
RE-CONNECT POWER!
Contact your Cutler-Hammer
distributor.
Reset the fault and restart.
Should the fault reoccur, contact
your Cutler-Hammer distributor.
