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

FC 300 Design Guide
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 located in par. group 7-2* and
7-3*.
Control Structure in Flux Sensorless (FC 302
only)
Control structure in Flux sensorless open loop and closed loop configurations.
In the shown configuration, 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*.
