● If the digital operation value exceeds the range of -32768 to 32767 as a result of shift addition, the digital operation value
is fixed to the lower limit value (-32768) or the upper limit value (32767).
● For the extension A/D converter module, go to "Ext. module 1_Module parameter" and set "Ext. module 1_CH A/D
conversion enable/disable setting" to "0: Enable", and then set the value to be added in CH Shifting amount to
conversion value (RWw12 to RWw15).
(3) Setting example
For the channel with the set input range of -10 to 10V, of the main A/D converter module, settings are
made as follows:
•CH Shifting amount to conversion value (RWw2 to RWw5): 20000
The digital output values and digital operation values are as follows:
*1 Because the value exceeds the range of -32768 to 32767, it is fixed to 32767 (the upper limit value).
