PID Setup Mode
The PID Setup (Proportional-Integral-Derivative) mode is comprised of parameter settings that are
specific to the PID operating mode. PID is a closed-loop control technique that seeks error minimization
by reacting to three values: One that is proportional to the error, one that is representative of the error, and
one that is representative of the rate of change of the error.
