(700) Valve opening
characteristics setting
Valve opening characteristic can be selected from the following.
(700) = Lin Linear
Y=X
(710) = EP25 Equal percentage 1:25 (R=25)
X-1
Y=(R -0.04)×1/0.96
(720) = EP50 Equal percentage 1:50 (R=50)
X-1
Y=(R -0.02)×1/0.98
(730) = qo25 Quick opening 25:1 (R=25)
-X
Y=(1-R )×1/0.96
(740) = qo50 Quick opening 50:1 (R=50)
-X
Y=(1-R )×1/0.98
User's definition〔11 polygonal line settings〕
(750) = USEr
The default value at shipping is (700) = (Lin) Linear. When user's
definition (USEr) is set, the following 11 data can be set
However, the setting range is between -20.0 and 120.0%.
Definition by user can be set by value (vALU) and operation (ACt).
(750,760) Input current 0% position = 0.0% (Default value)

7: Be sure to set all 11 date items. To use forced fully-close / fully-open
(parameter code: 500), set items so that stroke (Y) increases
according to input current (X) increases.
