Control Structure in Flux Sensorless
"
(FC 302 only)
Control structure in flux sensorless open-loop and closed-loop configurations.
In the configuration shown, 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 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*.
