3.2.4 Control Structure in Flux Sensorless
Control structure in Flux sensorless open loop and closed loop configurations.
In the shown configuration, par. H-41
Motor Control Principle
is set to “Flux sensorless [2]” and par. H-40
Configuration Mode
is set to “Speed open loop [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 PI-0#).
Select “Process [3]” in par. H-40
Configuration Mode
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 PI-2# and PI-3#.
