9.4.3 Methods 3 and 4: Homing on the positive home
switch and index pulse
Using methods 3 or 4, the initial direction of movement is dependent on the state of the
home switch. The home position is at the index pulse to either the left or right of the pint
where the home switch changes state. If the initial position is sited so that the direction of
movement must reverse during homing, the point at which the reversal takes place is
anywhere after a change of state of the home switch.

9.4.4 Methods 5 and 6: Homing on the negative home
switch and index pulse
Using methods 5 or 6, the initial direction of movement is dependent on the state of the
home switch. The home position is at the index pulse to either the left or the right of the
point where the home switch changes state. If the initial position is sited so that the
