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
(parameter 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
carried 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
converter. Contact your Danfoss supplier.
LIMIT VALUE FAULT [8]
The parameter values found for the motor are
outside the acceptable range within which the
frequency converter 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 accordance with the warning message. Press
the [CHANGE DATA key and select "CONTINUE"
if AMA is to continue despite the warning or press
the [STOP/RESET] key or disconnect terminal 18
from terminal 12 to discontinue 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 carried 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 ‘Continue’ or ‘Stop’.
