3.2 Main Menu - Load and Motor - Group 1

Parameters related to the motor nameplate load compen-
sations and application load type.
3.2.1 1-0* General Settings
1-00 Configuration Mode
Option: Function:
NOTICE
This parameter cannot be adjusted when
the motor is running.
[0] Open Motor speed is determined by applying a speed
Loop reference or by setting the wanted speed when
*
in local 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
[3] Closed
Loop
When set for Closed Loop, the commands
Reversing and Start Reversing do not
reverse the direction of the motor.
A reference form 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.
1-01 Motor Control Principle
Option: Function:
NOTICE
[0] U/f
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.
NOTICE
[1] VVC+
*
When parameter 1-10 Motor Construction is
set to PM-enabled options, only VVC
is available.
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.
Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
This parameter defines the term clockwise
corresponding to the LCP direction arrow. Used for
easy change of direction of shaft rotation without
swapping motor wires.
frequency converter is connected U⇒U; V⇒V; and
W⇒W to motor.
direction when frequency converter is connected
U⇒U; V⇒V; and W⇒W to motor.
Function:
Suitable for highly dynamic response.
Suitable for smooth steady-state operation.
Suitable for smooth steady-state operation with
lowest dynamic response.
