Homing depending on the positive limit switch and Z pulse (: mode 2)
Mode 3 and mode 4 Homing which depends on the home switch and Z pulse

Mode 3
Circumstance 1： When the home switch is OFF, MC_Home instruction is executed and the axis moves
in the positive direction at the first-phase speed. When the axis encounters that the
home switch is ON, the motion direction changes and the axis moves at the
second-phase speed. Where the first Z pulse is met is the home position when the
home switch is OFF.
Circumstance 2： When the home switch is ON, MC_Home instruction is executed and the axis directly
moves in the negative direction at the second-phase speed. Where the first Z pulse is
met is the home position while the home switch is OFF.

Mode 4
Circumstance 1： 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 axis moves at the second-phase
speed when the axis encounters that the home switch is ON. Where the first Z pulse is
met is the home position.
Circumstance 2： When the home switch is ON, MC_Home instruction is executed and the axis moves
in the negative direction at the second-phase speed. When the axis encounters that
the home switch is OFF, the motion direction changes and the axis moves at the
second-phase speed. Where the first Z pulse is met is the home position.
