Auto tuning
Purpose The auto tuning feature automatically calculates tuning values for PIDF
control modes.
Note Auto tuning is only available for PIDF control modes.
How auto tuning
works
The auto tuner disregards your current PIDF gain settings. It applies
the minimum required drive signal to ramp the feedback to 80% of the
auto tuning limits. It then measures the relationship between the
feedback velocity and the valve opening, and derives the minimum
PIDF gains required to track the command.
The majority of tests will run adequately with the settings calculated
through basic auto tuning, however, advanced auto tuning may be
used to optimize the results obtained through basic auto tuning.
Accepting the auto
tuning values
The Current column displays your current PIDF gain values. When
auto tuning completes successfully, the calculated tuning parameters
are loaded into the New Values column on the Auto-Tuning control
panel.
You can click Accept to transfer the auto-tuned values (New Values)
to the Current column and the tuning Adjustments tab.
