Position Auto Tune
SVI II ESD performs automatic determination of
the optimal valve position control parameters. In
addition to P, I, D, the position algorithm uses
damping, symmetry for exhaust and fill time con-
stants, dead zone and magnitude characteriza-
tion parameters. Auto Tune is optimized for 5%
step changes with negligible overshoot. After Auto
Tune process is completed, you can further adjust
positioner tuning parameters to more conserva-
tive or to more responsive values.
