Troubleshooting
WARNING/ALARM 35, Option fault
An option alarm is received. The alarm is option-specific.
The most likely cause is a power-up or a communication
fault.
WARNING/ALARM 36, Mains failure
This warning/alarm is only active if the supply voltage to
the drive is lost and parameter 14-10 Mains Failure is not
set to [0] No function.
Troubleshooting
•
Check the fuses to the drive and mains supply to
the unit.
ALARM 37, Phase imbalance
There is a current imbalance between the power units.
6 6
ALARM 38, Internal fault
When an internal fault occurs, a code number defined in
Table 6.5 is shown.
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.

Table 6.5 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 parameter 5-00 Digital I/O
Mode and parameter 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. Also check parameter 5-00 Digital
I/O Mode and parameter 5-02 Terminal 29 Mode.
WARNING 42, Overload of digital output on X30/6 or
overload of digital output on X30/7
For terminal X30/6, check the load connected to terminal
X30/6 or remove the short-circuit connection. Also check
parameter 5-32 Term X30/6 Digi Out (MCB 101) (VLT
General Purpose I/O MCB 101).
For terminal X30/7, check the load connected to terminal
X30/7 or remove the short-circuit connection. Check
parameter 5-33 Term X30/7 Digi Out (MCB 101) (VLT
General Purpose I/O MCB 101).

Text
The digital signal processor has received too many
unknown SPI telegrams. The AC drive also uses
this fault code if the MCO does not power up
correctly. This situation can occur due to poor EMC
protection or improper grounding.
RAM copy error.
Software version 48.3X or newer is used with MK1
control card. Replace with MKII issue 8 control
card.
Replace the control card.
LCP stack overflow.
Serial port overflow.
USB port overflow.
Parameter value is outside its limits.
Option in slot A: Hardware incompatible with the
control board hardware.
Option in slot B: Hardware incompatible with the
control board hardware.
Option in slot C0: Hardware incompatible with the
control board hardware.
Option in slot C1: Hardware incompatible with the
control board hardware.
Internal fault. Contact the Danfoss supplier or
Danfoss service department.
