Analog Output Terminals Section 7-5
Calculation Example When using three points, and applying scaling to the first and second inputs,
and the cumulative counter to the third input, the maximum AD conversion
cycle time can be obtained by using the following formula.
Formula: 3.21 + (0.055 x 2) + 0.035 = 3.355 ms
Note With the DRT2-DA04H, the conversion cycle time is within 250 ms even when
all of the math operations are being used.
