Soft-Charge Fault; Internal Fault; Heatsink Sensor - Danfoss VLT FC 102 Series Design Manual

General Specifications and ...
ALARM 30, Motor phase U missing
Motor phase U between the adjustable frequency drive
and the motor is missing.
Remove power from the adjustable frequency drive and
check motor phase U.
ALARM 31, Motor phase V missing
Motor phase V between the adjustable frequency drive
and the motor is missing.
Remove power from the adjustable frequency drive and
check motor phase V.
ALARM 32, Motor phase W missing
Motor phase W between the adjustable frequency drive
and the motor is missing.
Remove power from the adjustable frequency drive and
check motor phase W.
ALARM 33, Soft-charge fault
Too many power-ups have occurred within a short time
period. Let the unit cool to operating temperature.
WARNING/ALARM 34, Serial communication bus
communication fault
9 9
The serial communication bus on the communication
option card is not working.
WARNING/ALARM 36, Line failure
This warning/alarm is only active if the supply voltage to
the frequency converter is lost and 14-10 Mains Failure is
NOT set to [0] No Function. Check the fuses to the
frequency converter and mains supply to the unit.
ALARM 38, Internal fault
When an internal fault occurs, a code number defined in
Table 9.44 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 Danfoss supplier or
service department. Note the code number for further
troubleshooting directions.

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 5-00 Digital I/O Mode and
5-01 Terminal 27 Mode.
WARNING 41, Overload of digital output terminal 29
Check the load connected to terminal 29 or remove short-
circuit connection. Check 5-00 Digital I/O Mode and
5-02 Terminal 29 Mode.
