Circumstance 1： MC_Home instruction is executed and the axis moves in the positive direction at the
first-phase speed while the home switch is OFF. The motion direction changes and the
axis moves at the second-phase speed once the home switch becomes ON. And
where the axis stands is the home position at the moment the home switch becomes
OFF.
Circumstance 2： MC_Home instruction is executed and the axis directly moves in the negative direction
at the second-phase speed while the home switch is ON. And where the axis stands
is the home position at the moment when the home switch becomes OFF.

 Mode 20
Circumstance 1： MC_Home instruction is executed when the home switch is OFF and the axis moves
in the positive direction at the first-phase speed. Where the servo is is the home
position when the home switch is ON.
Circumstance 2： MC_Home instruction is executed when the home switch is ON and the axis moves in
the negative direction at the second-phase speed. The motion direction changes and
the axis moves at the second-phase speed when the home switch becomes OFF.
Where the servo is is the home position when the home switch is ON.
