WARNING 19
Fault in the EEprom on the power card
(EE ERROR POWER) There is a fault on the power
card EEPROM. The frequency converter will continue
to function, but is likely to fail at the next power-up.
Contact your Danfoss supplier.
WARNING 20
Fault in the EEprom on the control card
(EE ERROR CONTROL) There is a fault in the EE-
PROM on the control card. The frequency converter
will continue to function, but is likely to fail at the next
power-up. Contact your Danfoss supplier.
ALARM: 22
Auto-optimisation not OK
(AMA FAULT) A fault has been found during auto-
matic motor adaptation. The text shown in the display
indicates a fault message.
NB!
AMA can only be carried out if there are
no alarms during tuning.
CHECK 103, 105 [0]
Parameter 103 or 105 has a wrong setting. Correct the
setting and start AMA all over.
LOW P.105 [1]
The motor is too small for AMA to be carried out. If
AMA is to be enabled, the rated motor current (para-
meter 105) must be higher than 35% of the rated out-
put current of the frequency converter.
ASYMMETRICAL IMPEDANCE [2]
AMA has detected an asymmetrical impedance in the
motor connected to the system. The motor could be
defective.
MOTOR TOO BIG [3]
The motor connected to the system is too big for AMA
to be carried out. The setting in parameter 102 does
not match the motor used.
MOTOR TOO SMALL [4]
The motor connected to the system is too small for
AMA to be carried out. The setting in parameter 102
does not match the motor used.
TIME OUT [5]
AMA fails because of noisy measuring signals. Try to
start AMA all over a number of times, until AMA is car-
ried out. Please note that repeated AMA runs may heat
the motor to a level where the stator resistance R
S
is
increased. In most cases, however, this is not critical.
INTERRUPTED BY USER [6]
AMA has been interrupted by the user.
INTERNAL FAULT [7]
An internal fault has occurred in the frequency con-
verter. Contact your Danfoss supplier.
LIMIT VALUE FAULT [8]
The parameter values found for the motor are outside
the acceptable range within which the frequency con-
verter is able to work.
MOTOR ROTATES [9]
The motor shaft rotates. Make sure that the load is not
able to make the motor shaft rotate. Then start AMA
all over.
Warnings and alarms, cont.
ALARM 29
Heat sink temperature too high
(HEAT SINK OVER TEMP.):
If the enclosure is IP 00, IP 20 or NEMA 1, the cut-out
temperature of the heat-sink is 90°C. If IP 54 is used,
the cut-out temperature is 80°C.
The tolerance is ± 5°C. The temperature fault cannot
be reset, until the temperature of the heat-sink is below
60°C.
The fault could be the following:
-
Ambient temperature too high
-
Too long motor cable
-
Too high switching frequency.
ALARM: 30
Motor phase U missing
(MISSING MOT.PHASE U):
Motor phase U between frequency converter and mo-
tor is missing.
Turn off the frequency converter and check motor
phase U.
ALARM: 31
Motor phase V missing
(MISSING MOT.PHASE V):
Motor phase V between frequency converter and mo-
tor is missing.
Turn off the frequency converter and check motor
phase V.
