The automatic tune menu is used to engage pre-tune and/or self-tune to
assist setting up proportional bands and the integral and derivative time
values used by the control loops.
Pre-tune can be used to set PID parameters approximately. Self-tune (Pre-
tune needs to be run first) may then be used to optimize the tuning if
required. See the Tuning section on page 101 for more information.
FYI: Pre-tune can be set to run automatically after every power-up by
enabling Auto Pre-Tune (Not Recommended).
