■
PID3 display conversion parameter
Item Parameter
PID3 target value [FA-38]
PID3 feedback monitor [db-38]
PID3 target value set value [AJ-30]
PID4 display conversion parameter

Adjustment example 1) If you want to display 0 to 10V
(0 to 100%) as 0.1 to 0.5kPa in [db-30] when the
voltage is feed-backed to the analog input 1 [Ai1]
• Unit [AH-03] = 56 (kPa), decimal point position
[AH-06] = 02, zero point [AH-04] = 10, end point
[AH-05] = 50
• In this setting, display descriptions of zero point
and maximum point are set.
• An adjustment example is displayed at the bottom
of this section.
