" Control Structure in Flux Sensorless
Control structure in Flux sensorless open loop and closed-loop configurations. ( Only available in F C 302):
In the shown configuration, par. 1-01 Motor Control Principle is set to "Flux sensorless [2]" a n d par.
1-00 is set to "Speed open loop [0]". The resulti n g reference from the reference handling syste m is fed
through the ramp and speed limitations as determined b y the parameter settings indicated.
An e s timated 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 (pa r. 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 controlle d applic ation. The Process PID parameters are found in par. group
7-2* and 7-3*. Process PID is not available in this software release.
