GE AF-600 FP Operating Instructions Manual page 57

Warnings and Alarms
Troubleshooting:
Check for proper fan operation.
Cycle power to the drive and check that the fan
operates briefly at start up.
Check the sensors on the heatsink and control
card.
WARNING 24, External fan fault
The fan warning function is an extra protective function
that checks if the fan is running/mounted. The fan warning
can be disabled in SP-53 Fan Monitor ([0] Disabled).
Troubleshooting:
Check for proper fan operation.
Cycle power to the drive and check that the fan
operates briefly at start up.
Check the sensors on the heatsink and control
card.
ALARM 29, Heatsink temp
The maximum temperature of the heatsink has been
exceeded. The temperature fault will not reset until the
temperature falls below a defined heatsink temperature.
The trip and reset points are different based on the drive
power size.
8 8
Troubleshooting:
Check for the following conditions.
Ambient temperature too high.
Motor cable too long.
Incorrect airflow clearance above and below the
drive
Blocked airflow around the drive.
Damaged heatsink fan.
Dirty heatsink.
ALARM 30, Motor phase U missing
Motor phase U between the drive and the motor is
missing.
Remove power from the drive and check motor phase U.
ALARM 31, Motor phase V missing
Motor phase V between the drive and the motor is
missing.
Remove power from the drive and check motor phase V.
ALARM 32, Motor phase W missing
Motor phase W between the drive and the motor is
missing.
Remove power from the drive and check motor phase W.
ALARM 33, Inrush fault
Too many power-ups have occurred within a short time
period. Let the unit cool to operating temperature.
WARNING/ALARM 34, communication fault
The network on the communication option card is not
working.

WARNING/ALARM 36, Mains failure
This warning/alarm is only active if the supply voltage to
the drive is lost and SP-10 Line failure is NOT set to [0] No
Function. Check the fuses to the drive and mains power
supply to the unit.
ALARM 38, Internal fault
When an internal fault occurs, a code number defined in
the table below is displayed.
Troubleshooting
It may be necessary to contact your GE supplier or service

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.
Cycle power
Check that the option is properly installed
Check for loose or missing wiring
