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 Motor speed is determined by applying a speed
Loop 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 Motor Speed will be determined by a reference
Loop 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]

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.

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.
