Troubleshooting
•
Remove the power from the frequency converter
and check motor phase U.
ALARM 31, Motor phase V missing
Motor phase V between the frequency converter and the
motor is missing.
Troubleshooting
•
Remove the power from the frequency converter
and check motor phase V.
ALARM 32, Motor phase W missing
Motor phase W between the frequency converter and the
motor is missing.
Troubleshooting
•
Remove the power from the frequency converter
and check motor phase W.
ALARM 33, Inrush fault
Too many power-ups have occurred within a short time
period.
Troubleshooting
•
Let the unit cool to operating temperature.
WARNING/ALARM 34, Fieldbus communication fault
The fieldbus 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 frequency converter is lost and
is not set to option
[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
is displayed.
Troubleshooting
•
Cycle power.
•
Check that the option is properly installed.
•
Check for loose or missing wiring.
It may be necessary to contact the Danfoss supplier or
service department. Note the code number for further
troubleshooting directions.

to DSP.
1794
Power data not transferred correctly at power-up
to DSP.
1795
The DSP has received too many unknown SPI
telegrams.
The frequency converter also uses this fault code if
the MCO does not power up correctly, for example
due to poor EMC protection or improper
grounding.

control board hardware.
5124
Option in slot B: Hardware incompatible with
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 the Danfoss supplier or
Danfoss Service Department.
Table 4.10 Internal Fault Codes
ALARM 39, Heat sink sensor
No feedback from the heat sink 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 gatedrive card, or the ribbon cable between the
power card and gatedrive card.
WARNING 40, Overload of digital output terminal 27
Check the load connected to terminal 27 or remove the
short circuit connection. Check
and
5-01 Terminal 27 Mode
.
WARNING 41, Overload of digital output terminal 29
Check the load connected to terminal 29 or remove the
short circuit connection. Check
and
parameter 5-02 Terminal 29 Mode
