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

3 Introduction to AutomationDrive FC 300

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

Control structure in Flux sensorless open loop and closed loop configurations.

In the shown configuration, par. 1-01
[0]". The resulting 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
application. The Process PID parameters are found in par. group 7-2* and 7-3*.
