Table A-1: Fault Codes (Continued)
ᕃ Programmable.
Fault
Code Fault
Possible Cause Solution
9 Undervoltage ᕃ DC link voltage is below the defined
voltage limits:
• Supply voltage too low (most
probable cause)
• Inverter internal fault
In case of temporary supply voltage
break, reset the fault and restart the
inverter. Check the supply voltage. If
it is adequate, an internal failure has
occurred.
Contact your Cutler-Hammer
distributor.
10 Input Line
Supervision
ᕃ
Input line phase is missing. Check supply voltage and cable.
11 Output phase
supervision
ᕃ
Current measurement has detected
there is no current in one motor
phase. Check motor cable and motor.
12 Brake Chopper
Supervision
• No brake resistor installed
• Brake resistor is broken
• Brake chopper failure
Check brake resistor.
If the resistor is OK, the chopper is
faulty.
Contact your Cutler-Hammer
distributor.
13 Inverter
Undertemperature Heatsink temperature is under -10°C
14 Inverter
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 ᕃ Motor stall protection has tripped. Check motor.
16 Motor
Overtemperature
ᕃ
• Motor overheating was detected
by inverter motor temperature
model
• Motor is overloaded
Decrease the motor load.
If no motor overload exists, check the
temperature model parameters.
17 Motor underload ᕃ Motor underload protection tripped.
22 EEPROM
checksum fault Parameter save fault
• Faulty operation
• Component failure
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.
26 Startup prevented Start-up of the drive was prevented. Cancel prevention of start-up.
29 Thermistor fault ᕃ The thermistor input of option board
detected an increase in 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.)
