12 : mode 12)
 Mode 13
Circumstance 1： 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 axis moves 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 2： MC_Home instruction is executed and the axis moves in the negative 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 moves at the second-phase speed and where
the first Z pulse is met is the home position when the home switch is ON.
