MG.02.C2.02 - VLT
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.
For normal speed control (References).
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
Direction Clockwise
must be set to
Function:
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.
Normal running mode, including slip- and load compensations.
Function:
With more torque characteristics it is possible to run low energy
consuming, as well as high torque applications.
Motor shaft output provides constant torque under variable
speed control.
This function automatically optimizes energy consumption in
centrifugal pump and fan applications. See par. 14-41
