Warnings and Alarms
Instruction Manual High Power
WARNING/ALARM 28, Brake check failed
The brake resistor is not connected or not working.
Check 2-15 Brake Check.
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
frequency converter power size.
Troubleshooting
Check for the following conditions.
Ambient temperature too high.
6 6
Motor cable too long.
Incorrect airflow clearance above and below the
frequency converter
Blocked airflow around the frequency converter.
Damaged heatsink fan.
Dirty heatsink.
For the D, E, and F Frame sizes, this alarm is based on the
temperature measured by the heatsink sensor mounted
inside the IGBT modules. For the F Frame sizes, this alarm
can also be caused by the thermal sensor in the Rectifier
module.
Troubleshooting
Check fan resistance.
Check soft charge fuses.
IGBT thermal sensor.
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, 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 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
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.
