Autotuning:
Autotuning is the automatic calculation and
entering of the control parameters (P, I and D) into memo-
ry. Autotuning will also automatically set anti-reset wind-
up (Ar).There are two types of Autotuning that can be
performed by the controller, Autotuning at main setpoint
or Autotuning at 10% of full scale below main setpoint.
The latter may yield slightly different values, not as pre-
cise, but the process overshoot encountered during the
autotuning procedure would not be as much. Enter the
value for the type of autotuning you would like to run on
your particular application based on overshoot tolerances
and the precision of the PID parameters needed. For
more information on principles of Autotuning, refer to
Appendix A. See also page 36.
Setting:
0 - Autotuning off
1 - Autotuning performed at setpoint
2 - Autotuning performed at 10% of F.S. below setpoint
