Min - Max motor frequency: 20-1000 Hz.
Select the motor frequency value from the
motor nameplate data. If a value different
from 50 Hz or 60 Hz is selected, adapt the
load independent settings in
1-50 Motor
Magnetisation at Zero Speed

230/400 V motors, set the nameplate data
for 230 V/50 Hz. To run at 87 Hz, adapt

1-29 Automatic Motor Adaptation (AMA)
Option:
Function:
The AMA function optimises dynamic motor
performance by automatically optimising the
advanced motor parameters (
1-30 Stator
Resistance (Rs)
to
1-35 Main Reactance (Xh)
) at
motor standstill.
Activate the AMA function by pressing [Hand
on] after selecting
[1] Enable complete AMA
or
[2] Enable reduced AMA
. See also
chapter 3.7.1 Final Set-Up and Test
. After a
normal sequence, the display reads: "Press [OK]
to finish AMA". After pressing [OK], the
frequency converter is ready for operation.
This parameter cannot be adjusted while the
motor is running.

reduced
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
frequency converter and the motor.
Note:
•
For the best adaptation of the frequency
converter, run AMA on a cold motor.
•
AMA cannot be performed while the motor is
running.
•
AMA cannot be performed on permanent magnet
motors.
NOTICE
It is important to set motor parameter group 1-2*
correctly, since these form part of the AMA algorithm.
An AMA must be performed to achieve optimum
dynamic motor performance. It may take up to 10 min,
depending on the power rating of the motor.
NOTICE
Avoid generating external torque during AMA.
NOTICE
If one of the settings in parameter group
