An estimated speed feedback is generated to the speed PID to control the output frequency. The speed PID mustbe set with its P, I, and D parameters (parameter group 7-0* Speed PID control).Select [3] Process in parameter 1-00 Configuration Mode to use the process PID control for closed-loop control of that is,speed or pressure in the controlled application. The process PID parameters are found in parameter groups 7-2* Process Ctrl.Feedb and 7-3* Process PID Ctrl.Basic Operating Principles ...
