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.

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.

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.
