The digital output of the PWM function is 3 seconds high, 7 seconds low, 3 seconds high, 7
seconds low and continues in that pattern as long as parameter "En" = high.
Calculation rule
Q = 1, for (Ax – Min) / (Max – Min) of time period PT
Q = 0, for PT – [(Ax – Min) / (Max – Min)] of time period PT.
Note: Ax in this calculation refers to the actual value Ax as calculated using the Gain and
Note: Ax in this calculation refers to the actual value Ax as calculated using the Gain and
Offset. Min and Max refer to the minimum and maximum values specifed for the range.
