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 operation).
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) during 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 compressor 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 frequency
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 resistor.
CAUTION
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 missing.
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.
