Appendix D Explanation of Homing Modes
D_
Homing depending on the home switch, positive limit switch and Z pulse (

: mode 8)

Mode 9
Circumstance 1
：
MC_Home instruction is executed and the axis moves in the positive direction at the
first-phase speed when the home switch is OFF. The axis moves at the second-phase
speed when the home switch is ON. The motion direction changes and the axis
moves at the second-phase speed when the home switch is OFF. And where the first
Z pulse is met is the home position.
Circumstance 2
：
When the home switch is ON MC_Home instruction is executed and the axis moves in
the positive direction at the second-phase speed. The motion direction changes and
the axis moves at the second-phase speed when the home switch is OFF. And where
the first Z pulse is met is the home position.
Circumstance 3
：
MC_Home instruction is executed and the axis moves in the positive direction at the
first-phase speed when the home switch is OFF. The motion direction changes and
the axis moves at the first-phase speed when the home switch is OFF and the positive
limit switch is ON. The axis moves at the second-phase speed and where the first Z
pulse is met is the home position when the home switch is ON.
