4.2. Parameter Group 1: Load/Motor
1-00 Configuration Mode
Option: Function:
Use this parameter for selecting the application control principle
to be used when a Remote Reference is active.
NB!
Changing this parameter will reset parameters
3-00, 3-02 and 3-03 to their default values.
NB!
This parameter cannot be adjusted while motor
runs.
[0 ]
*
Speed Open Loop For normal speed control (References).
[3] Process Closed Loop Enables process closed loop control. See par. group 7-3* for
further information on PI-controller.
When running in process closed loop, par. 4-10
Motor Speed
Direction
must be set to
Clockwise
[0]
1-01 Motor Control Principle
Option: Function:
[0] U/f Is used for parallel connected motors and/or special motor ap-
plications. The U/f settings are set in parameters 1-55 and 1-56.
NB!
When running U/f control slip- and load compen-
sations are not included.
[1]
*
VVC+ Normal running mode, including slip- and load compensations.
1-03 Torque Characteristics
Option: Function:
With more torque characteristics it is possible to run low energy
consuming, as well as high torque applications.
[0 ]
*
Constant Torque Motor shaft output provides constant torque under variable
speed control.
[2] Automatic Energy Op-
tim.
This function automatically optimizes energy consumption in
centrifugal pump and fan applications. See par. 14-41
