Circumstance 1： MC_Home instruction is executed while the home switch is OFF and the axis starts to
move in the negative direction at the first-phase speed. When the home switch is ON,
the axis starts to move at the second-phase speed. Where the axis stands is the
home position when the home switch is OFF.
Circumstance 2： MC_Home instruction is executed while the home switch is ON and the axis moves in
the negative direction at the second-phase speed. Where the axis stands is the home
position when the home switch is OFF.
Circumstance 3： MC_Home instruction is executed while the home switch is OFF. The axis moves in
the negative 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 negative
limit switch is ON. When the home switch is ON, the motion direction changes again
and the axis moves at the second-phase speed. Where the axis stands is the home
