Setup Items
Ten-segment linearizer I/O
• Loop number (control input channel number when the PV/SP computation
function Is ON)
The setup items of ten-segment linearizer output parameters are set for each loop.
When the PV/SP computation function is ON, you can set each setting item of the ten
segment linearizer I/O settings for each control input channel. When changing these
parameters, this setting is used to select the target loop number [1] to [6] (initial value
is 1). The loop number is displayed up to the number of loops or channels you
specified at the time of purchase.
• Input type (when PV/SP computation function is OFF)
Only during loop control with PV switching, select [PV1] or [PV2]. During single loop
control and cascade control, only [PV1] is displayed.
• Mode
When using the ten-segment linearizer approximation, set the mode to [Biasing] or
[Approximation]. If not, set to [Off] (initial setting).
• Input/Output
If you are using the ten-segment linearizer approximation, set between 2 to 11 points
of input/output values. If the number of segmental points is less than 11, set the next
Input value of the next segmental point to the same value as (or a value less than) the
Input value of the final segment.
The selectable range is indicated below.
• For ten-segment linearizer bias
Selectable range of input value: EU (–5.0% to 105.0%) of the measurement span
(initial value for points other than the second is
0.0%, initial value for the second point is 100%)
Selectable range of output value: EUS (–100.0% to 100.0%) of the measurement
span (initial value is 0.0%)
The selectable range is displayed in a pop-up window.
• For ten-segment linearizer approximation
Selectable range of input value: EU (–5.0% to 105.0%) of the measurement span
(initial value for points other than the second is
0.0%, initial value for the second point is 100%)
Selectable range of output value: EU (–5.0% to 105.0%) of the measurement span
(initial value is 0.0%)
The selectable range is displayed in a pop-up window.
