Control Structure In Flux Sensorless (Fc 302 Only); Control Structure In Flux With Motor Feedback - Danfoss VLT AutomationDrive FC 300 Design Manual

FC 300 Design Guide

3.2.5. Control Structure in Flux Sensorless (FC 302 only)

Control structure in Flux sensorless open loop and closed loop configurations.
In the shown configuration, par. 1-01
reference from the reference handling system is fed through the ramp and speed limitations as determined by the parameter settings indicated.
An estimated speed feedback is generated to the Speed PID to control the output frequency.
The Speed PID must be set with its P,I, and D parameters (par. group 7-0*).
Select "Process [3]" in par. 1-00 to use the process PID control for closed loop control of i.e. speed or pressure in the controlled application. The Process
PID parameters are found in par. group 7-2* and 7-3*.

3.2.6. Control Structure in Flux with Motor Feedback

Control structure in Flux with motor feedback configuration (only available in FC 302):
In the shown configuration, par. 1-01
Motor Control Principle
is set to "Flux sensorless [2]" and par. 1-00 is set to "Speed open loop [0]". The resulting
Motor Control Principle is set to "Flux w motor feedb [3]" and par. 1-00 is set to "Speed closed loop [1]".
