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
Fault
Code Fault Possible Cause Solution
1 Overcurrent The SVX9000/SPX9000 has detected
a high current (>4xI
n
) in its output
due to:
• sudden heavy load increase
• short in the motor
• short in the cables to the motor
• unsuitable motor
Check loading.
Check motor.
Check cables.
2 Overvoltage 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
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.
3** Ground (Earth)
Fault
Current sensing indicates that the
sum of motor phase currents is not
zero.
• insulation failure in motor or
motor cables
Check the motor and motor cables.
5 Charging Switch The charging switch was open when
the START command was been given
due to:
• faulty operation
• component failure
Reset the fault and restart.
Should the fault re-occur, contact
your Cutler-Hammer distributor.
6 Emergency stop An Emergency stop signal was
received from one of the digital
inputs
Determine the reason for the
Emergency stop and remedy it.
7 Saturation trip
• defective component
• motor or motor cable short
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.
8 System fault
• component failure
• faulty operation
Note: exceptional fault data record,
see the Active Fault Menu and Fault
Time Data Record for more
information
Reset the fault and restart.
Should the fault reoccur, contact
your Cutler-Hammer distributor.
