1-23 Motor Frequency
Range: Function:

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.

NOTICE
It is important to set parameter group 1-2* Motor Data
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 minutes,
depending on the power rating of the motor.
NOTICE
Avoid generating external torque during AMA.
NOTICE
If 1 of the settings in parameter group 1-2* Motor Data is
changed, parameter 1-30 Stator Resistance (Rs) to
parameter 1-39 Motor Poles return to their default
setting.

Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
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] Enable complete AMA or
[2] Enable reduced AMA. See also
chapter 3.6.1 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.

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.
