Troubleshooting
WARNING/ALARM 34, Fieldbus communication fault
The network on the communication option card is not
working.
WARNING/ALARM 35, Option faultOut of frequency range
An option alarm is received. The alarm is option-specific.
The most likely cause is a power-up or a communication
fault.
WARNING/ALARM 36, Mains failure
This warning/alarm is only active if the supply voltage to
the frequency converter is lost and SP-10 Line failure is NOT
set to [0] No Function. Check the fuses to the frequency
converter and mains power supply to the unit.
ALARM 37, Phase imbalance
There is a current imbalance between the power units
ALARM 38, Internal fault
When an internal fault occurs, a code number defined in
Table 5.4 is displayed.
Troubleshooting
Cycle power
Check that the option is properly installed
Check for loose or missing wiring
It may be necessary to contact your GE supplier or service
department. Note the code number for further trouble-
shooting directions.

2821 Serial port overflow
2822 USB port overflow
3072-5122 Parameter value is outside its limits
5123 Option in slot A: Hardware incompatible with
control board hardware
5124 Option in slot B: Hardware incompatible with
control board hardware
5376-6231 Internal fault. Contact your GE supplier or GE
Service Department.

ALARM 39, Heatsink sensor
No feedback from the heatsink temperature sensor.
The signal from the IGBT thermal sensor is not available on
the power card. The problem could be on the power card,
on the gate drive card, or the ribbon cable between the
power card and gate drive card.
WARNING 40, Overload of digital output terminal 27
Check the load connected to terminal 27 or remove short-
circuit connection. Check E-00 Digital I/O Mode and
E-51 Terminal 27 Mode.
WARNING 41, Overload of digital output terminal 29
Check the load connected to terminal 29 or remove short-
circuit connection. Check E-00 Digital I/O Mode and
E-52 Terminal 29 Mode.
WARNING 42, Overload of digital output on X30/6 or
overload of digital output on X30/7
For X30/6, check the load connected to X30/6 or remove
the short-circuit connection. Check E-56 Term X30/6 Digi
Out (OPCGPIO).
For X30/7, check the load connected to X30/7 or remove
the short-circuit connection. Check E-57 Term X30/7 Digi
Out (OPCGPIO).
ALARM 45, Earth fault 2
Earth (ground) fault on start-up.
Troubleshooting
ALARM 46, Power card supply
The supply on the power card is out of range.
There are three power supplies generated by the switch
mode power supply (SMPS) on the power card: 24 V, 5 V,
±18 V. When powered with three phase mains voltage, all
three supplies are monitored.
Troubleshooting
WARNING 47, 24 V supply low
The 24 V DC is measured on the control card. The external
24 V DC backup power supply may be overloaded,
otherwise contact the GE supplier.
WARNING 48, 1.8 V supply low
The 1.8 V DC supply used on the control card is outside of
allowable limits. The power supply is measured on the
control card. Check for a defective control card. If an
option card is present, check for an overvoltage condition.
DET-618C
Check for proper earthing (grounding) and loose
connections.
Check for proper wire size.
Check motor cables for short-circuits or leakage
currents.
Check for a defective power card.
Check for a defective control card.
Check for a defective option card.
If a 24 V DC power supply is used, verify proper
supply power.
