VLT
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 optimises dynamic motor
performance by automatically optimising the
advanced motor parameter 1-30 Stator Resistance
(Rs) to parameter 1-35 Main Reactance (Xh) while
the motor is stationary.
No function.
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:
- 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)

1-29 Automatic Motor Adaption (AMA)
Option:
[2] Enable
Reduced
AMA
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.
NOTICE
•
For the best adaptation of the frequency
converter, run AMA on a cold motor.
•
AMA cannot be performed while the motor is
running.
NOTICE
Avoid generating external torque during AMA.
NOTICE
If one of the settings in parameter group 1-2* Motor
Data is changed, the advanced motor parameters,
parameter 1-30 Stator Resistance (Rs) to
parameter 1-39 Motor Poles, return to default setting.
If LC filter is used, set the frequency converter to run in U/f
control mode (recommended), or perform reduced AMA in
VVC + mode. If LC filter is not used, perform complete AMA.
4.2.4 1-3* Adv. Motor Data I
Set parameters for advanced motor data. The motor data
in parameters 1-30 to 1-39 must match the motor for
optimal performance. If the motor data is not known,
running an AMA is recommended.
Function:
-
Parameter 1-38 q-axis
Inductance (Lq)
- Parameter 1-44 d-axis
Inductance Sat. (LdSat)
- Parameter 1-45 q-axis
Inductance Sat. (LqSat)
Performs a reduced AMA of the stator resistance
R (parameter 1-30 Stator Resistance (Rs)) in the
s
system only. If an LC filter is used between the
frequency converter and the motor, select this
option.
