Motor Control Principle Configuration Mode
In the shown configuration, par. 1-01 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*).
Configuration Mode
Select "Process [3]" in par. 1-00 to use the process PID control for closed-loop control of, e.g., speed or pressure in the controlled
application. The Process PID parameters are found in par. group 7-2* and 7-3*.
