M0=On: Disable modifying the D/A conversion curve.
3. Program
Description
•
When X0 = On, write K20,480 (H’5000, i.e. 0101 0000 0000 0000 in binary) to CR#1
to configure CH5 ~ CH6 to mode 1 (voltage output mode).
•
When X1 = On, write K0 (OFFSET value for CH51 ~ CH6) into CR#22 ~ 23 and
K1,000 (GAIN value for CH5 ~ CH6) into CR#28 ~ 29.
•
When X1 goes from On to Off, set M0 = On to disable modifying the D/A conversion
curve. Write K4,096 (H’A000, i.e. 1010 0000 0000 0000 in binary) into CR#33 to
disable modifying the D/A conversion curve in CH5 ~ CH6.

Example#4: Adjusting the D/A Conversion Curve for the Current Output Mode
1. Description
Example for ELC-AN06AANN.
•
When CR#1 is set to current output mode (mode 2), the OFFSET value will be set to
4mA (K800) and the GAIN value to 12mA (K2,400), i.e. input current 4mA ~ +20mA
will correspond to values 0 ~ +4,000.
•
When CR#1 is set to current output mode (mode 3), the OFFSET value will be set to
0mA (K0) and GAIN value to 10mA (K2,000), i.e. output current 0mA ~ +20mA will
correspond to values 0 ~ +4,000.
•
If the default current output mode (mode 2 and mode 3) does not meet the
application requirements, adjustments can be made to. For example, Set the
OFFSET for CH5 ~ CH6 to 6mA (K1,200) and the GAIN to 13mA (K2,600).
•
The D/A conversion curve only needs to be configured once.
