Enter the value from the motor nameplate
data. The default value corresponds to the
nominal rated output. This parameter is
available when
is set to
[1] PM, non-salient
SPM
, that is, the parameter is valid for PM
and non-salient SPM motors only.
1-29 Automatic Motor Adaption (AMA)
Option:
Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
NOTICE
Terminal 27 digital input
(
parameter 5-12 Terminal 27 Digital Input
)
has coast inverse as the default setting.
This setting means that AMA cannot be
performed if terminal 27 is switched off.
The AMA function optimizes dynamic motor
performance by automatically optimizing the
advanced motor parameters
(
parameter 1-30 Stator Resistance (Rs)
to
parameter 1-35 Main Reactance (Xh)
) while the
motor is stationary.

No function.
[1] Enable
Complete
AMA
Depending on the option selected in
parameter 1-10 Motor Construction
, the AMA is
performed on different parameters.
•
If
[0] Asynchron
is selected, the AMA is
performed on:
-
Parameter 1-30 Stator
Resistance (Rs)
.
-
Parameter 1-35 Main Reactance
(Xh)
.
•
If
[1] PM, non-salient SPM, non Sat
is
selected, the AMA is performed on:
-
Parameter 1-30 Stator
Resistance (Rs)
.
-
Parameter 1-37 d-axis
Inductance (Ld)
•
If
[2] PM, salient IPM, non Sat
is selected,
the AMA is performed on:
1-29 Automatic Motor Adaption (AMA)
Option:
Function:
-
Parameter 1-30 Stator
Resistance (Rs)
.
-
Parameter 1-37 d-axis
Inductance (Ld)
-
Parameter 1-38 q-axis
Inductance (Lq)
•
If
[3] PM, salient IPM, Sat
is selected, the
AMA is performed on:
-
Parameter 1-30 Stator
Resistance (Rs)
.
-
Parameter 1-37 d-axis
Inductance (Ld)
-
Parameter 1-38 q-axis
Inductance (Lq)
-
Parameter 1-44 d-axis
Inductance Sat. (LdSat)
-
Parameter 1-45 q-axis
Inductance Sat. (LqSat)
[2] Enable
Reduced
AMA
Performs a reduced AMA of the stator resistance
R
s
(
parameter 1-30 Stator Resistance (Rs)
) in the
system only. If an LC filter is used between the
frequency converter and the motor, select this
option.
When
parameter 1-10 Motor Construction
is set to options
that enable permanent motor mode, the only option
available is
[1] Enable Complete AMA
.
Activate the AMA function by pressing [Hand On] after
selecting
[1] Enable Complete AMA
or
[2] Enable Reduced
AMA
. After a normal sequence, the display reads:
Press [OK]
to finish AMA
. After pressing [OK], the frequency converter
is ready for operation.
