Warnings and alarm messages
ALARM 21
Auto-optimisation OK
Press the [STOP/RESET] key or disconnect terminal
18 from terminal 12. This alarm indicates that the AMA
is OK and that the drive is correctly adapted to the mo-
tor.
ALARM 22
Auto-optimisation not OK
[AUTO MOTOR ADAPT OK]
A fault has been found during automatic motor adap-
tation. Press the [STOP/RESET] key or disconnect
terminal 18 from terminal 12. Check the possible
cause to the fault related to the alarm message given.
The figure after the text is the error code, which can be
seen in the fault log in parameter 615. Automatic motor
adaptation does not update parameters. You may
choose to run a reduced automatic motor adaptation.
CHECK P.103,105 [0]
[AUTO MOT ADAPT FAIL]
Parameter 102, 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 (param-
eter 105) must be higher than 35% of the rated output
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 RS 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.
WARNING 39 - 42
A fault have been encountered during automatic motor
adaptation. Check the possible fault causes in accord-
ance with the warning message. Press the [CHANGE
DATA key and select "CONTINUE" if AMA is to con-
tinue despite the warning or press the [STOP/RESET]
key or disconnect terminal 18 from terminal 12 to dis-
continue AMA.
WARNING: 39
CHECK P.104,106
The setting of parameter 102, 104 or 106 is probably
wrong. Check the setting and choose `Continue' or
`Stop'.
WARNING: 40
CHECK P.103,105
The setting of parameter 102, 103 or 105 is probably
wrong. Check the setting and choose `Continue' or
`Stop'.
WARNING: 41
MOTOR TOO BIG
The motor used is probably too big for AMA to be car-
ried out. The setting in parameter 102 may not match
the motor. Check the motor and choose `Continue' or
`Stop'.
WARNING: 42
MOTOR TOO SMALL
The motor used is probably too small for AMA to be
carried out. The setting in parameter 102 may not
match the motor. Check the motor and choose `Con-
tinue' or `Stop'.
