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.

control board hardware
5125 Option in slot C0: Hardware incompatible with
control board hardware
5126 Option in slot C1: Hardware incompatible with
control board hardware
5376-6231 Internal fault. Contact yourGE supplier or GEService
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.
AF-650 GP Operating Instructions
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
short-circuit connection. Check E-56 Term X30/6 Digi Out
(OPCGPIO).
For X30/7, check the load connected to X30/7 or remove
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: 24V, 5V,
+/- 18V. When powered with three phase mains voltage,
all three supplied are monitored.
Troubleshooting
WARNING 47, 24V supply low
The 24 V DC is measured on the control card. The external
24V DC backup power supply may be overloaded,
otherwise contact your GE supplier.
WARNING 48, 1.8V supply low
The 1.8V 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.
WARNING 49, Speed limit
When the speed is not within the specified range in F-18
and F-17, the drive will show a warning. When the speed is
below the specified limit in H-36 Trip Speed Low [RPM]
(except when starting or stopping) the drive will trip.
ALARM 50, Auto tune calibration failed
Contact your GE supplier or GE Service Department.
ALARM 51, Auto tune check U
The settings for motor voltage, motor current, and motor
power are wrong. Check the settings in parameters P-02,
P-03, P-06, P-07, F-04 and F-05.
ALARM 52, Auto tune low I
The motor current is too low. Check the setting in
F-43 Current Limit.
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 24V DC power supply is used, verify proper
supply power.
