speed when the home switch is ON and where the first Z pulse is met is the home
position.
Circumstance 2： MC_Home instruction is executed and the axis moves in the negative direction at the
second-phase speed when the home switch is ON. The motion direction changes and

the first Z pulse is met is the home position.
Circumstance 3： When the home switch is OFF, MC_Home instruction is executed and the axis moves
in the positive direction at the first-phase speed. 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 still moves at the first-phase speed when the home switch
