4.2.1. 1-2* Motor Data
Enter the correct motor nameplate data (power, voltage, frequency, current and speed).
Run AMT, see par. 1-29.
Factory settings for advanced motor data, par. 1-3*, are automatically calculated.
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
Function:
Is used for parallel connected motors and/or special motor applications. The U/f settings are set in parameters
1-55 and 1-56.
NB!
When running U/f control slip- and load compensations 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.
AEO Minimum Magnetisation
14-41 .
Function:
This parameter is only relevant when parameter 1-00
parameter is used for determining the reference or setpoint handling when changing from Auto Mode to Hand
Mode on the LCP.
In Hand Mode the drive always runs in Open Loop configuration regardless of setting in par. 1-00
Mode
. Local potentiometer (if present) or Arrow up/down determines output frequency limited by Motor Speed
High/Low Limit (parameters 4-14 and 4-12).
If par. 1-00 Configuration Mode is set to Open Loop
If par. 1-00 is set to Process Closed Loop
change via local potentiometer or Arrow up/down. The change is limited by Reference Max/Min (parameters
3-02 and 3-03).
