Table A-1: Fault Codes (Continued)
Programmable.
“A” faults only.
Fault
Code Fault
Possible Cause Solution
9 Undervoltage DC-link voltage is under the voltage
limits defined in
•
most probable cause: too low a
supply voltage
• drive
internal fault
In case of temporary supply voltage
break, reset the fault and restart the
drive. Check the supply voltage. If it
is adequate, an internal failure has
occurred.
Contact your Cutler-Hammer
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 measurement has detected
that there is no current in one motor
phase. Check motor cable and motor.
13 Drive
undertemperature Heatsink temperature is under -10
°
C. Provide supplemental heating, or
relocate drive.
14 Drive
overtemperature Heatsink temperature is over 90
°
C.
Overtemperature warning is issued
when the heatsink temperature
exceeds 85
°
C.
Check the correct amount and flow of
cooling air.
Check the heatsink for dust.
Check the ambient temperature.
Make sure that the switching
frequency is not too high in relation
to ambient temperature and motor
load.
15 Motor stalled Motor stall protection has tripped. Check motor.
16 Motor
overtemperature
•
motor overheating has been
detected by drive motor
temperature model
•
motor is overloaded
Decrease the motor load.
If no motor overload exists, check the
temperature model parameters.
17 Motor underload Motor underload protection has
tripped.
22 EEPROM
checksum fault Parameter save fault
•
faulty operation
•
component failure
Contact your Cutler-Hammer
distributor.
24 Counter fault Values displayed on counters are
incorrect.
25 Microprocessor
watchdog fault
•
faulty operation
•
component failure
Reset the fault and restart.
Should the fault re-occur, contact
your Cutler-Hammer distributor.
29 Thermistor fault The thermistor input of option board
has detected increase of the motor
temperature. Check motor cooling and loading.
Check thermistor connection.
(If thermistor input of the option
board is not in use, it has to be short
circuited.)
32 Fan cooling The cooling fan did not start when
commanded Contact your Cutler-Hammer
distributor.
34 Internal bus
communication Ambient interference or defective
hardware Should the fault re-occur, contact
your Cutler-Hammer distributor.
35 Application fault Selected application does not
function Contact your Cutler-Hammer
distributor.
