WARNING/ALARM 13: Overcurrent
The inverter's peak current limit (approx. 200% of rated
output current) has been exceeded. The warning will
last approx. 1-2 sec, and the adjustable frequency
drive will then trip and emit an alarm. Switch off the
adjustable frequency drive and check whether the mo-
tor shaft can be turned, and whether the size of the
motor is suitable for the adjustable frequency drive.
ALARM 14: Earth fault
There is a discharge from the output phases to earth,
either in the cable between the adjustable frequency
drive and the motor, or in the motor. Turn off the ad-
justable frequency drive and remove the earth 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 mains supply to the adjustable
frequency drive and remove the short-circuit.
WARNING/ALARM 17: Serial communication time-
out
There is no serial communication to the adjustable fre-
quency drive. The warning will only be active when 514
Bus timeout function
is set to a value other than OFF.
If parameter 514
Bus timeout function
is set to
Stop
and trip
[5], it will first give a warning and then ramp
down and trip out accompanied by an alarm. Param-
eter 513
Bus timeout
can if required be increased.
WARNING/ALARM 18: HPFB bus timeout
There is no serial communication to the adjustable fre-
quency drive's communication option card. This warn-
ing will only be active when parameter 804
Bus timeout
function
is set to a value other than OFF. If parameter
804
Bus timeout function
is set to
Stop and trip
, it will
first give a warning and then ramp down and trip out
accompanied by an alarm. Parameter 803
Bus time-
out
can if required 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 ad-
justable frequency drive is in
Process regulation, closed
loop
(parameter 100) the warning will be active in the
display. If the adjustable frequency drive is in another
mode than
Process regulation, closed loop
, bit 008000
Out of frequency range
in extended status word will be
active, but there will not be a warning in the display.
WARNING/ALARM 34: HPFB communication fault
Communication fault only occurs in Fieldbus versions.
Regarding alarmtype, please see parameter 953 in
fieldbus literature.
ALARM 35: Inrush fault
This alarm occurs when the adjustable frequency drive
has been connected to the mains supply too many
times within 1 minute.
WARNING/ALARM 36: Overtemperature
If the temperature inside the power module rises
above 75 - 85 °C (depending on the device) the ad-
justable frequency drive will emit a warning, and the
motor will continue to run unchanged. If the tempera-
ture continues to rise, the switch frequency is reduced
automatically. See
Temperature-dependent switching
frequency
.
If the temperature inside the power module rises
above 92 - 100 °C (depending on the unit) the adjust-
able frequency drive will cut out. The temperature fault
cannot be reset until the temperature has dropped to
below 70 °C. The tolerance is ± 5 °C. The temperature
can be caused by the following:
-
The ambient temperature too high.
-
Motor cable too long.
-
Too high mains voltage.
ALARM 37-45: Internal fault
If one of these failures occurs, please contact Danfoss.
Alarm 37, internal fault number 0: Communication fault
between control card and BMC.
Alarm 38, internal fault number 1: Flash EEPROM fault
on control card.
Alarm 39, internal fault number 2: RAM fault on control
card.
Alarm 40, internal fault number 3: Calibration constant
in EEPROM.
Alarm 41, internal fault number 4: Data values in EE-
PROM.
Alarm 42, internal fault number 5: Fault in motor pa-
rameter database.
Alarm 43, internal fault number 6: General power card
fault.
