1-23 Motor Frequency
Range: Function:
NOTICE
Size [20 -
related 1000
*
From software version 6.72 onwards,
Hz]
the output frequency of the frequency
converter is limited to 590 Hz.
Select the motor frequency value from the
motor nameplate data. If a value other than
50 Hz or 60 Hz is selected, adapt the load-
independent settings in parameter 1-50 Motor
Magnetisation at Zero Speed to
parameter 1-53 Model Shift Frequency. For 87
Hz operation with 230/400 V motors, set the
nameplate data for 230 V/50 Hz. To run at 87
Hz, adapt parameter 4-13 Motor Speed High
Limit [RPM] and parameter 3-03 Maximum
Reference.
1-24 Motor Current
Range: Function:
NOTICE
Size [ 0.10 -
related 10000.00 A]
*
This parameter cannot be
adjusted while the motor is
running.
Enter the nominal motor current
value from the motor nameplate data.
The data is used for calculating motor
torque, motor thermal protection, and
so on.
1-25 Motor Nominal Speed
Range: Function:
NOTICE
Size [100 -
related 60000 RPM]
*
This parameter cannot be
adjusted while the motor is
running.
Enter the nominal motor speed value
from the motor nameplate data. The
data is used for calculating automatic
motor compensations.
1-29 Automatic Motor Adaptation (AMA)
Option: Function:
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)) at motor
standstill.
Activate the AMA function by pressing [Hand
on] after selecting [1] or [2]. See also

NOTICE
It is important to set motor parameter group 1-2*
correctly, since these parameters form part of the AMA
algorithm. An AMA must be performed to achieve
optimum dynamic motor performance. Depending on
the power rating of the motor, It takes up to 10 min.
NOTICE
Avoid generating external torque during AMA, by discon-
necting the motor shaft from the application.
NOTICE
If one of the settings in parameter group 1-2* is
changed, parameter 1-30 Stator Resistance (Rs) to
parameter 1-39 Motor Poles, the Advanced Motor
Parameters return to default setting.

Function:
chapter 3.4 Automatic Motor Adaptation. After a
normal sequence, the display will read: "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.

h
Performs a reduced AMA of the stator
resistance R in the system only. Select this
s
option if an LC filter is used between the
frequency converter and the motor.
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.
