2.15.9.7 Homing Method 7: Homing on the Home Switch & Index Pulse
Using this method the initial direction of movement is positive (if the homing switch is inactive). The home position is the
first index pulse to the negative side of the position where the homing switch becomes active.
Axis will accelerate to fast homing velocity in the positive 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 the negative 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 7) is detected.
NOTE: if the axis is on the wrong side of the homing switch when homing is started then the axis will move positive until
it contacts the positive limit switch (A2). Upon activating the positive limit switch the axis will change direction (negative)
following the procedure as detailed above, but moving negative instead of positive and without stopping on detection
of the homing switch rising edge.
