Homing on the home switch and Z pulse (

: mode 5; : mode 6)

 Mode 7~ mode 10 Homing which depends on the home switch, positive limit switch and Z pulse

Mode 7

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 motion direction changes and 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 when the home switch is OFF.

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. Where the first Z pulse is met is the

home position when the home switch is OFF.

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 starts to move at the second-phase speed when the home switch is ON. Where

the first Z pulse is met is the home position when the home switch is OFF.
