When running U/f, control slip and load
compensations are not included.
Used for parallel-connected motors and/or special
motor applications. Set the U/f settings in
parameter 1-55 U/f Characteristic - U and
parameter 1-56 U/f Characteristic - F.

This parameter cannot be adjusted while
the motor is running.
Motor speed is determined by applying a speed
reference or by setting the wanted speed when
in hand-on mode.
Open loop is also used if the frequency
converter is part of a closed-loop control system
based on an external PI controller providing a
speed reference signal as output.
NOTICE
When set for Closed Loop, the commands
Reversing and Start Reversing do not
reverse the direction of the motor.
A reference from the built-in PI controller
determines the motor speed. The built-in PI
controller varies the motor speed as of a closed-
loop control process (for example, constant
pressure or flow). Configure the PI controller in
parameter group 20-** Drive Closed Loop.

Function:
Normal running mode, including slip and load
compensations.
Function:
For speed control of centrifugal pumps and fans.
Also to be used when controlling more than 1
motor from the same frequency converter (for
example, multiple condenser fans or cooling
tower fans). Provides a voltage that is optimized
for a squared torque load characteristic of the
motor.
For optimum energy efficient speed control of
centrifugal pumps and fans, it provides a
voltage that is optimized for a squared torque
load characteristic of the motor. In addition, the
AEO feature adapts the voltage exactly to the
current load situation, thereby reducing energy
consumption and audible noise from the motor.

easy change of direction of shaft rotation without
swapping motor wires.
