3. Devices
 X0 = On: Set the input mode of the signals at CH3 as mode 4.
 X1 = On: Set Offset value of CH3 as 8mA (12,800) and Gain value as 14mA (22,400).
 M0 = On: Disable CH3 set value changing.
4.
Program explanation
 When X0 = On, set CR#4 as K4 (H’4) and the signal input mode at CH3 as mode 4 (current input mode).
 When X1 = On, write K12,800 (Offset value of CH3) into CR#30 and K22,400 (Gain value of CH3) into
CR#36.
 When X1 goes from On to Off, set M0 = On to disable the adjustment on A/D conversion curve. Write K4
(H’4) into CR#40 to disable CH3 set value changing.

3.7.6 Adjusting D/A Conversion Curve in Voltage Output Mode
1.
Description
 Take 06XA CH5 for example. When CR#6 is set as voltage output mode (mode 0), the Offset value will
be set as 0V (0) and Gain value as 5V (5V/0.3215mV=16,000), i.e. output voltage -10V ~ 10V will
correspond to values -32,000 ~ +32,000.
 If you cannot use the default voltage output mode (mode 0), you can make adjustments on the D/A
conversion curve according to your actual need. For example, set the Offset of CH5 ~ CH6 as 2V
(2V/0.3215mV=6,400) and Gain as 6V (6V/0.3215mV=19,200).

 You only need to set up the D/A conversion curve for once. Set up CR#40 (Set value changing prohibited)
to prevent incorrect operations.
