Danfoss VLT Micro Drive FC 51 Series Programming Guide

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 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.
[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
AEO Minimum Magnetisation .
1-05 Hand Mode Configuration
Option: Function:
This parameter is only relevant when parameter 1-00 Configuration Mode is set to Process Closed Loop [3]. The
parameter is used for determining the reference or setpoint handling when changing from Auto Mode to Hand
Mode on the LCP.
[0] Speed Open Loop In Hand Mode the drive always runs in Open Loop configuration regardless of setting in par. 1-00
Configuration
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).
[2]
*
As configuration in par.
1-00
If par. 1-00 Configuration Mode is set to Open Loop [1] function is as described above.
If par. 1-00 is set to
Process Closed Loop [3] changing from Auto mode to Hand mode results in a setpoint
change via local potentiometer or Arrow up/down. The change is limited by Reference Max/Min (parameters
3-02 and 3-03).
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.
