Analog_Input_32bit_Value = (Analog_Input_16bit_Value - Offset) * Gain / 256
The Gain value is signed.
Example: using analog input as speed reference.
The speed reference is 32-bits, so the 32-bit value will be used.
Let's say that the maximum speed is 30000 rpm and the unit is inc/s with 4096 inc per motor revolution.
Maximum speed: 30000 rpm -> 500 rev/s -> 2048000 inc/s
The maximum 16-bit analog input is 32767
Gain = 2048000 / 32767 * 256 = 16000
