Change of digital value during the rate control
When the digital value is changed again during the rate control, the rate control will continue until a new digital value is output
in analog. In this case, setting the digital value that reverses the direction of increase or decrease changes the digital limit
value used for the rate control depending on the direction of increase/decrease.
Ex.
The following figure shows the case where 'CH1 Digital value' (Un\G460) is set to 4000  8000  2000 with the following
settings.
• Output range: -10 to 10V
• 'CH1 Increase digital limit value' (Un\G514): 300
• 'CH1 Decrease digital limit value' (Un\G516): 900
