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].

Function:
Compressor For speed control of screw and scroll
torque compressors. Provides a voltage which is
optimized for a constant torque load charac-
teristic of the motor in the entire range down
to 10 Hz.
Variable For speed control of centrifugal pumps and
torque fans. Also to be used when controlling more
than one motor from the same frequency
converter (e.g. multiple condenser fans or
cooling tower fans). Provides a voltage which
is optimised for a squared torque load
characteristic of the motor.
Auto Energy For optimum energy efficient speed control
