2.15.9.10 Homing Method 10: Homing on the Home Switch & Index Pulse
Using this method the initial direction of movement is positive. The home position is the first index pulse to the positive
side of the position where the homing switch becomes inactive.
Axis will accelerate to fast homing velocity in the positive direction and continue until Homing Switch (selectable via
Var_Home_Switch_Input Variable) is deactivated (falling edge) shown at position A.
If the homing switch is already active when the homing routine commences then this does not effect this mode of
homing as the procedure is searching for falling edge of homing switch in both cases.
Axis will continue running at fast homing velocity in the positive direction until the rising edge of the first index pulse
(position 10) 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)
continuing motion until it sees the rising edge of the homing switch. The axis will then stop and follow the procedure as
detailed above.
