Table B-1: Fault Codes (Continued)
Fault
Code Fault Possible Cause Solution
9** Undervoltage DC-link voltage is less than the
minimum safe operating voltage
limit.
• most probable cause: too low a
supply voltage
• SVX9000/SPX9000 internal fault
If there was a supply voltage loss or
dip, reset the fault and restart the
SVX9000/SPX9000. Check the supply
voltage. If it was within specification
at the time of the fault, an internal
failure has occurred.
Contact your Eaton distributor.
10** Input line
supervision
Input line phase is low or missing. Check the utility supply voltage,
cables and connections.
11** Output phase
supervision
Current sensing indicates that there
is no current in one motor phase.
Check the motor cables, connections
and motor.
12 Brake chopper
supervision
• no brake resistor installed
• brake resistor is open
• brake chopper failure
Check the brake resistor.
If the resistor is ok, the chopper is
faulty. Contact your Eaton
distributor.
13 SVX9000/SPX9000
undertemperature
Heatsink temperature is under 14°F
(-10°C)
Provide supplemental heating or
relocate the SVX9000/SPX9000 to a
warmer location.
14 SVX9000/SPX9000
overtemperature
Heatsink temperature is over 194°F
(90°C).
An overtemperature warning is
issued when the heatsink
temperature exceeds 185°F (85°C), a
fault occurs at 194°F (90°C). Check for
the correct amount and unrestricted
flow of cooling air.
Check the heatsink for dust or dirt
buildup.
Check the highest ambient
temperature level.
Make sure that the switching
frequency is not set too high in
relation to ambient temperature and
motor load.
15** Motor stalled
•motor or load mechanical failure
• load is too high
• stall parameter settings incorrect
Check motor, mechanical system and
load level.
Confirm the stall parameter settings.
16** Motor
overtemperature
• motor is overloaded
• motor overheating has been
detected by the SVX9000/
SPX9000 motor temperature
model
Decrease the motor load.
If no motor overload exists, check the
temperature model parameters.
17** Motor underload
• mechanical or load problems
• underload parameter settings
incorrect
Check the motor. Check for a loose
belt, broken coupling or load
problems. Confirm the underload
parameter settings.
22 EEPROM
checksum fault
Parameter save fault
• faulty operation
• component failure
Upon reset of this fault, the SVX9000/
SPX9000 will automatically reload
the parameter default settings. Check
all parameter settings after reset. If
the fault reoccurs, contact your Eaton
distributor.
