Common applications for PID control:
Flow control: Use a flow sensor to feedback the flow data and perform accurate flow
control.
Pressure control: Use a pressure sensor to feedback the pressure data and perform
precise pressure control.
Air volume control: Use an air volume sensor to feedback the air volume data to achieve
excellent air volume regulation.
Temperature control: Use a thermocouple or thermistor to feedback temperature data for
comfortable temperature control.
Speed control: Use a speed sensor or encoder to feedback motor shaft speed or input
another machine speed as a target value for closed loop speed control of the master-slave
operation. Pr.10-00 sets the PID set point source (target value).
