Setting example
Ex.
When the following values are used for the A/D converter module with the input range of 0 to 5V
• 'CH1 Scaling enable/disable setting' (Un\G504): Enable (0)
• 'CH1 Scaling upper limit value' (Un\G506): 12000
• 'CH1 Scaling lower limit value' (Un\G508): 2000
• 'CH1 Conversion value shift amount' (Un\G472): 2000
• 'CH1 Digital clipping enable/disable setting' (Un\G510): Enable (0)
*1 These values are also applied to the case of digital output values (32 bits).
When the digital clipping function is used with the scaling function, shift function, and difference conversion
function, scale conversion, shift-and-add, and difference conversion are performed on the value obtained after
digital clipping.
