In order to program the motor to home towards your optical sensor, simply use the
Z command and state the max number of steps you want it to search for home. The
unit will either stop at the opto sensor or when it finishes moving your designated
number of steps. For example:
/1Z500000R
Motor will take 500,000 steps and stop OR Motor will stop once the optical sensor
has been interrupted. Only input #3 can work with the optical sensor.
The LED output on pin 9 can output a max of 20mAmps (200 ohms internal resistor
and 5VDC output)
