YT-3400/3450 series
6.3.3.4 P2 (KP2) and D2 (Kd2) values
P2 and D2 values’ principles are same as P1 and D1, but these values are applicable for
only when input signal is decreasing.
6.3.3.5 P_ (KP_) and D_ (Kd_) values
P_ and D_ values’ principles are same as P and D, but these values are applicable only
when the positioner’s actual stroke reaches its target stroke per input signal.
6.3.3.6 PT1 (PT1) and PT2 (PT2) values
PT value indicates minimum time duration of internal signal. PT1 is for increased input
signal, and PT2 is for decreased input signal’s PT values.
6.3.3.7 Period T (PERIOD T)
Period T indicates the positioner’s internal control time interval. As default, positioner will
check current position respective to current input signal in every 100 msec.
6.3.3.8 Auto DZ (AUTO dZ)
After the auto calibration, the positioner will create deadzone automatically. In some cases,
due to the valve packing friction or to some other reasons, deadzone may need to be
increased to reduce hunting or oscillation.
