Shift Function

Normal
This function allows adding the set input value shift amount to the digital value.
The analog output value reflects the change in the input value shift amount on a realtime basis. Therefore, fine adjustment
can be easily performed when the system starts.
Operation
When the D/A conversion is performed on the digital value, the value obtained by adding 'CH1 Input value shift amount'
(Un\G480) to 'CH1 Digital value' (Un\G460) is used for the D/A conversion.
When the digital value after the addition exceeds the range as the result of the shift processing, the value is fixed to the lower
limit value or the upper limit value.
When a value is written to 'CH1 Input value shift amount' (Un\G480), the set value is added to the digital value even if
'Operating condition setting request' (Y9) is not turned on and off.
Setting method
Set a value for "Input value shift amount".
