2.15.9.18 Homing Method 21: Homing without an Index Pulse
Using this method the initial direction of movement is negative (if the homing switch is inactive). The home position is
the leading edge of the homing switch.
Axis will accelerate to fast homing velocity in the negative direction and continue until the homing switch 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 positive direction. Motion will continue until the falling edge of the
homing switch is detected (position B), where the axis will decelerate to 0 velocity.
Axis will then accelerate to slow homing velocity in the negative direction. Motion will continue until the rising edge of
the homing switch is detected (position C), where the axis will decelerate to 0 velocity.
Axis will then accelerate to slow homing velocity in the positive direction. Motion will continue until the falling edge of
the homing switch is detected (position 21). This is the home position (excluding offset).
