Overload Of Digital Output Terminal; Overload Of Digital Output On X30/7 - Danfoss VLT FC 100 Series Programming Manual

Troubleshooting
Damaged heatsink fan.
Dirty heatsink.
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 communi-
cation fault
The serial communication bus 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 Adjustable frequency drive is lost and 14-10 Mains
Failure is NOT set to [0] No Function. Check the fuses to the
Adjustable frequency drive and line 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

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.
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 5-32 Term X30/6 Digi
Out (MCB 101).
For X30/7, check the load connected to X30/7 or remove
the short-circuit connection. Check 5-33 Term X30/7 Digi
Out (MCB 101).
