5.2.2 1-0* General Settings
Define whether the frequency converter operates in open
loop or closed loop.
1-00 Configuration Mode
Option: Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
[0] Open
Loop
Motor speed is determined by applying a speed
reference or by setting desired speed when in
Hand Mode.
Open Loop is also used if the frequency converter
is of a closed loop control system based on an
external PID controller providing a speed reference
signal as output.
[3] Closed
Loop
Motor Speed will be determined by a reference
from the built-in PID controller varying the motor
speed as of a closed loop control process (e.g.
constant pressure or flow). The PID controller must
be configured in parameter group 20-** Feedback
or via the Function Set-ups accessed by pressing
[Quick Menus].
NOTICE
When set for Closed Loop, the commands Reversing and
Start Reversing do not reverse the direction of the
motor.
1-20 Motor Power [kW]
Range: Function:
Size
related*
[ 0.09 -
2000.00
kW]
Enter the nominal motor power in kW
according to the motor nameplate data.
The default value corresponds to the
nominal rated output of the unit.
Depending on the choices made in
0-03 Regional Settings, either
parameter 1-20 Motor Power [kW] or
1-21 Motor Power [HP] is made invisible.
1-22 Motor Voltage
Range: Function:
Size
related*
[ 10 -
1000 V]
Enter the nominal motor voltage
according to the motor nameplate
data. The default value corresponds to
the nominal rated output of the unit.
1-23 Motor Frequency
Range: Function:
Size
related*
[20 -
1000
Hz]
Select the motor frequency value from the
motor nameplate data. For 87 Hz operation
with 230/400 V motors, set the nameplate
1-23 Motor Frequency
Range: Function:
data for 230 V/50 Hz. Adapt
parameter 4-13 Motor Speed High Limit [RPM]
and 3-03 Maximum Reference to the 87 Hz
application.
1-24 Motor Current
Range: Function:
Size
related*
[ 0.10 -
10000.00 A]
Enter the nominal motor current
value from the motor nameplate
data. This data is used for
calculating motor torque, motor
thermal protection etc.
1-25 Motor Nominal Speed
Range: Function:
Size related* [100 - 60000
RPM]
Enter the nominal motor speed
value from the motor nameplate
data. This data is used for
calculating automatic motor
compensations.
1-29 Automatic Motor Adaptation (AMA)
Option: Function:
NOTICE
This parameter cannot be adjusted
while the motor is running.

.
[2] Enable
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.
NOTICE
Parameter 1-29 Automatic Motor Adaptation (AMA) have
no effect when 1-10 Motor Construction = [1] PM, non
salient SPM.
Activate the AMA function by pressing [Hand on] after
selecting [1] or [2]. See also the item Automatic Motor
Adaptation in the Design Guide. After a normal sequence,
the display reads: Press [OK] to finish AMA. After pressing
[OK], the frequency converter is ready for operation.
