E.3.13: Lower Home Inside Index

Direction of Motion: Positive

Home is the first index pulse on the positive side of the negative edge of a momentary

home switch. Initial direction of motion is positive if the home switch is inactive. If the initial

motion leads away from the home switch, the axis reverses on encountering the positive

limit switch; then, if a negative limit switch is activated before the home switch, an error is

generated.
