Output value
After the closed-loop control is used to select the source of the feedback given to
the closed loop, the source value of the feedback will be compared with the
present value of the command sent to the closed loop. Owing to the PID
closed-loop control, the source value of the feedback is the same as the present
value of the command. The maximum cumulative error set is used to limit the
difference between the source value of the feedback and the present value of the
command. If the difference is greater than the maximum cumulative error, there
will no output.
