Appendix D Explanation of Homing Modes

Homing depending on the home switch, positive limit switch and Z pulse (

: mode 10)

Mode 11~ mode 14 Homing which depends on the home switch, negative limit switch and Z pulse

 Mode 11

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

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

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 while the home switch is OFF.

Circumstance 2： MC_Home instruction is executed and the axis moves in the positive direction at the

second-phase speed while the home switch is ON. And where the first Z pulse is met

is the home position while the home switch is OFF.

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 when the

home switch is ON. Where the first Z pulse is met is the home position while the home

switch is OFF.
