2.15.9.11 Homing Method 11: Homing on the Home Switch & Index Pulse
Using this method the initial direction of movement is negative (if the homing switch is inactive). The home position is
the first index pulse to the positive of the position where the homing switch becomes active.
Axis will accelerate to fast homing velocity in the negative direction and continue until Homing Switch (selectable via
Var_Home_Switch_Input Variable) is activated (rising edge) shown at position A. Axis then decelerates to zero velocity.
If the homing switch is already active when the homing routine commences then this initial move is not executed.
Axis will then accelerate to fast homing velocity in positive direction. Motion will continue until first the falling edge of the
Homing switch is detected (position B) and then the rising edge of the first index pulse (position 11) is detected.
NOTE: if the axis is on the wrong side of the homing switch when homing is started then the axis will move negative until
it contacts the negative limit switch (A1). Upon activating the negative limit switch the axis will change direction (positive)
following the procedure as detailed above, but moving positive instead of negative and without stopping on detection
of the homing switch rising edge.
