Mode 8

Circumstance 1: MC_Home instruction is executed and the axis moves in the positive 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 negative direction at the

second-phase speed when the home switch is ON. The motion direction changes and the

axis moves at the second-phase speed when 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 positive direction at the

first-phase speed when the home switch is OFF. The motion direction changes and the axis

moves at the first-phase speed when the home switch is OFF and the positive 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 when the home switch is OFF.

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.
