WARNING/ALARM 12, Torque limit:
The torque is higher than the value in par. 4-16 (in motor operation) or
the torque is higher than the value in par. 4-17 (in regenerative opera-
tion).
WARNING/ALARM 13, Over Current:
The inverter peak current limit (approx. 200% of the rated current) is
exceeded. The warning will last approx. 8-12 sec., then the frequency
converter trips and issues an alarm. Turn off the frequency converter and
check if the motor shaft can be turned and if the motor size matches the
frequency converter.
ALARM 14, Earth fault:
There is a discharge from the output phases to earth, either in the cable
between the frequency converter and the motor or in the motor itself.
Turn off the frequency converter and remove the earth fault.
ALARM 15, In-complete hardware:
A fitted option is not handled by the present control board (hardware or
software).
ALARM 16, Short-circuit:
There is short-circuiting in the motor or on the motor terminals.
Turn off the frequency converter and remove the short-circuit.
WARNING/ALARM 17, Control word timeout:
There is no communication to the frequency converter.
The warning will only be active when par. 8-04 is NOT set to
OFF
.
If par. 8-04 is set to
Stop
and
Trip
, a warning appears and the frequency
converter ramps down until it trips, while giving an alarm.
par. 8-03 Control word Timeout Time could possibly be increased.
Alarm 18, Start Failed
The speed has not been able to exceed Max Start Speed (par. 1-77) dur-
ing the start within the allowed time (par. 1-79). This may be caused by
a blocked rotor.
Warning/ Alarm 19, Discharge Temperature High
Warning:
The discharge temperature exceeds the level programmed in par. 28-24.
If so programmed in par. 28-25 the drive lowers the speed of the com-
pressor in an attempt to lower the discharge temperature.
Alarm:
The discharge temperature exceeds the level programmed in par. 28-26.
WARNING 25, Brake resistor short-circuited:
The brake resistor is monitored during operation. If it short-circuits, the
brake function is disconnected and the warning appears. The frequency
converter still works, but without the brake function. Turn off the fre-
quency converter and replace the brake resistor (see par. 2-15 Brake
Check.
ALARM/WARNING 26, Brake resistor power limit:
The power transmitted to the brake resistor is calculated as a percentage,
as a mean value over the last 120 s, on the basis of the resistance value
of the brake resistor (par. 2-11) and the intermediate circuit voltage. The
warning is active when the dissipated braking power is higher than 90%.
If
Trip
[2] has been selected in par. 2-13, the frequency converter cuts
out and issues this alarm, when the dissipated braking power is higher
than 100%.
WARNING 27, Brake chopper fault:
The brake transistor is monitored during operation and if it short-circuits,
the brake function disconnects and the warning comes up. The frequency
converter is still able to run, but since the brake transistor has short-
circuited, substantial power is transmitted to the brake resistor, even if it
is inactive. Turn off the frequency converter and remove the brake re-
sistor.
Warning: There is a risk of substantial power being
transmitted to the brake resistor if the brake transistor
is short-circuited.
ALARM/WARNING 28, Brake check failed:
Brake resistor fault: the brake resistor is not connected/working.
ALARM 29, Frequency converter over temperature:
If the enclosure is IP 20 or IP 21/TYPE 1, the cut-out temperature of the
heat-sink is 95
o
C +5
o
C, dependent on size of frequency converter. The
temperature fault cannot be reset, until the temperature of the heatsink
is below 70
o
C +5
o
C.
The fault could be:
- Ambient temperature too high
- Too long motor cable
ALARM 30, Motor phase U missing:
Motor phase U between the frequency converter and the the motor is
missing.
Turn off 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.
Turn off 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 miss-
ing.
Turn off the frequency converter and check motor phase W.
ALARM 33, Inrush fault:
Too many power-ups have occurred within a short time period. See the
chapter
Specifications
for the allowed number of powerups within one
minute.
WARNING/ALARM 34, Fieldbus communication fault:
The fieldbus on the communication option card is not working.
WARNING 35, Out of frequency range:
This warning is active if the output frequency has reached par. 4-52
Warning speed low or par. 4-53 Warning speed high. If the frequency
converter is in par. 1-00 Process control, closed loop [3], the warning is
active in the display. If the frequency converter is not in this mode bit
008000 Out of
frequency range
in extended status word is active but
there is no warning in the display.
ALARM 38, Internal fault:
Contact the local Danfoss supplier.
WARNING 47, 24 V supply low:
The external 24 V DC backup power supply may be overloaded, otherwise
contact the local Danfoss supplier.
WARNING 48, 1.8 V supply low:
Contact the local Danfoss supplier.
ALARM 49, Speed Limit:
When the speed is not within the specified range in par. 4-11 and par.
4-13. the drive will show a warning. When the speed is below the speci-
fied limit in par. 1-86 (except when starting or stopping) the drive will
trip.
