Example- Set Output after Distance
Set output bit 1 after a distance of 1000 counts from the start of the move. The accuracy of the
trippoint is the speed multiplied by the sample period.

Example - Start Motion on Input
This example waits for input 1 to go low and then starts motion.
NOTE: The AI command actually halts execution of the program until the input occurs. If you do not
want to halt the program sequences, you can use the Input Interrupt function (II) or use a conditional
jump on an input, such as JP #GO,@IN[1] = 1.
