The analog input of the MDrive Motion Control is a 0 to 5V, 10 bit resolution input. This offers the user the ability to receive input
from temperature, pressure or other forms of sensors, and then control events based upon the input.
The value of this input will be read using the I5 instruction, which has a range of 0 to 1024, where 0 = 0 volts and 5 = 5.0 volts. You
may then use the program branch (BR) or subroutine call (CL) instructions to control events within the system.
