WARNING/ALARM 12: Current limit
The output current is greater than the value in
parameter 221 Current Limit I
The adjustable frequency drive will trip after a
set period of time, as selected in parameter
409 Trip delay overcurrent .
WARNING/ALARM 13: Overcurrent
The inverter's peak current limit (approx. 200% of
rated output current) has been exceeded. The warning
will last for approx. 1-2 secs, and the adjustable
frequency drive will then trip and give an alarm.
Switch off the adjustable frequency drive and check
that the motor shaft can be turned and that the motor
size fits the adjustable frequency drive.
ALARM: 14: Ground fault
There is a discharge from the output phases to ground,
either in the cable between the adjustable frequency
drive and the motor, or in the motor.
Turn off the adjustable frequency drive and
remove the ground fault.
ALARM: 15: Switch mode fault
Fault in switch mode power supply (internal supply).
Contact your Danfoss supplier.
ALARM: 16: Short-circuit
There is a short-circuit on the motor terminals
or in the motor.
Disconnect the AC line supply to the adjustable
frequency drive and remove the short-circuit.
WARNING/ALARM 17: Serial commu-
nication timeout
There is no serial communication to the
adjustable frequency drive.
The warning will only be active when parameter 514 Bus
time interval function has been set to a value other than
OFF. If parameter 514 Bus time interval function has
been set to Stop and trip [5], it will first give a warning
and then until it trips and issues an alarm. Parameter
513 Bus time interval could possibly be increased.

WARNING/ALARM 18: HPFB bus timeout
There is no serial communication to the adjustable
frequency drive's communication option card.
The warning will only be active when parameter 804 Bus
time interval function has been set to a value other than
OFF. If parameter 804 Bus time interval function has
been set to Stop and trip, it will first give a warning and
then ramp down, trip and issue an alarm. Parameter
803 Bus time interval could possibly be increased.
WARNING 33: Out of frequency range
This warning is active if the output frequency has
reached Output frequency low limit (parameter 201)
or Output frequency high limit (parameter 202).
If the VLT adjustable frequency drive is in a mode other
than Process regulation, closed loop (parameter 100)
the warning will be active in the display. If the VLT
adjustable frequency drive is in a mode other than
Process regulation, closed loop bit 008000 Out of
frequency range in the extended status word will be
active, but there will be no warning in the display.
WARNING/ALARM: 34: HPFB communication fault
Communication fault only occurs in Profibus versions.
ALARM 35: Inrush fault
This alarm appears when the adjustable frequency
drive has been connected to the AC line supply
too many times within 1 minute.
WARNING/ALARM 36: Overtemperature
If the temperature of the heatsink moves above
167°F - 185°F (75° - 85°C), depending on the unit,
the adjustable frequency drive gives a warning,
and the motor continues to operate unchanged.
If the temperature continues to rise, the switching
frequency is reduced automatically.
See Temperature-dependent switching frequency .
If the temperature of the heatsink rises above 199°F
- 212°F (92 - 100 °C), depending on the unit, the
adjustable frequency drive will trip.
The temperature fault cannot be reset until the
temperature of the heatsink has dropped to below
158°F (70 °C). The tolerance is ±9°F (±5 °C). The
temperature can be caused by the following:
- Ambient temperature too high.
- Motor cable too long.
