 Mode 12
Circumstance 1： MC_Home instruction is executed and the axis moves in the negative 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. 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 positive direction at the
second-phase speed while the home switch is ON. The motion direction changes and
the axis moves at the second-phase speed while 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 negative direction at the
first-phase speed while the home switch is OFF. The motion direction changes and the
axis moves at the first-phase speed while the home switch is OFF and the negative
limit switch is ON. The axis still moves at the first-phase speed when the home switch
is ON. The motion direction changes and the axis moves at the first-phase speed while
the home switch is OFF. The axis moves at the second-phase speed while the home
switch is ON. And where the first Z pulse is met is the home position.
