Introduction to PID Contro l Appendix D: PID Control • D - 3 Saturation Once the input value has wandered outsid e Propor- tional Mode’ s throttling range, the out put percentag e will be at 0% (if below the Throttling Range) or at 100% (if above the Throttling Range).

Other PID Features Appendix D: PID Control • D - 5 Therefore, as the input valu e gradually drops below the setpoint, the Proportional M ode of PID wi ll gradually bring the output percentage down. When the input drops below the low end of the throttling ran ge, the output will be zero.

The output will remain in saturation at 20% until a higher output percentage is called for .
