This parameter is available only when
parameter 1-10 Motor Construction
is set to options that enable permanent motor mode.
Table 52: Range:
Min: 0.1 Nm
Max: 10000.0 Nm
Default value: Configuration dependent
1-29 Automatic Motor Adaption (AMA)
Default value: [0] Off
Parameter type: Option
2-setup: All setups
Conversion index: -
Data type: u_int8
Change during operation: False
The AMA function optimizes dynamic motor performance by automatically optimizing the advanced motor parameters while the
motor is stationary.
Table 53: Option:
[0] Off
No function.
[1] Enable
Complete
AMA
When
parameter 1-10 Motor Construction
is set to
[0] Asynchron
, perform AMA of
parameter 1-30 Stator Resist-
ance (Rs)
to
parameter 1-35 Main Reactance (Xh)
.
When
parameter 1-10 Motor Construction
is set to options that enable permanent motors, perform AMA of
parameter 1-30 Stator Resistance (Rs)
and
parameter 1-37 d-axis Inductance (Ld)
for SPM, and
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)
, and
parameter 1-45 q-axis Inductance Sat. (LqSat)
for IPM.
[2] Enable Re-
duced
AMA
Performs a reduced AMA of the stator resistance R
s
in the system only. Select this option if an LC filter is used
between the drive and the motor.
N O T I C E
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 drive is ready for operation.
For the best adaptation of the drive, run AMA on a cold motor.
AMA cannot be performed while the motor is running.
AMA cannot be performed on a motor with a bigger power rating than the drive, for example, when a 5.5 kW (7.4 hp) motor is
connected to a 4 kW (5.4 hp) drive.
N O T I C E
Avoid generating external torque during AMA.
N O T I C E
If 1 of the settings in
parameter group 1-2* Motor Data
is changed, the advanced motor parameters,
parameter 1-30 Stator Resist-
ance (Rs)
to
parameter 1-39 Motor Poles
, return to default setting.
N O T I C E
Perform a full AMA without filter only, while reduced AMA should be run with a filter.
4.3.4 1-3* Motor Data II
This parameter group comprises input data from the nameplate on the connected motor.
