Parameter Descriptions
1-26 Motor Cont. Rated Torque
Range: Function:
parameter is valid for PM, non-salient SPM,
and salient IPM 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.
[0] Off No function.
*
[1] Enable Depending on the option selected in
Complete parameter 1-10 Motor Construction, the AMA is
AMA performed on different parameters.
•
If [0] Asynchron is selected, the AMA is
performed on:
-
-
-
-
•
If [1] PM, non-salient SPM, non Sat is
selected, the AMA is performed on:
-
-
•
If [2] PM, salient IPM, non Sat is selected,
the AMA is performed on:

[2] Enable Perform a reduced AMA of the stator resistance
Reduced R (parameter 1-30 Stator Resistance (Rs)) in the
s
AMA 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.
