Appendix D Explanation of Homing Modes 
D-5 
Mode 5 and mode 6 Homing which depends on the home switch and Z pulse 
 Mode 5 
Circumstance 1:   When the home switch is ON, MC_Home instruction is executed and the axis moves 
in the positive direction at the second-phase speed. Where the first Z pulse is met is 
the home position while the home switch is OFF. 
Circumstance 2:   When the home switch is OFF, MC_Home instruction is executed and the axis moves 
in the negative direction at the first-phase speed. When 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. 
 Mode 6 
Circumstance 1:   When the home switch is ON, MC_Home instruction is executed and the axis moves 
in the positive direction at the second-phase speed. When 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. 
Circumstance 2:   When the home switch is OFF, MC_Home instruction is executed and the axis moves 
in the negative direction at the first-phase speed. While the home switch is ON, the 
axis moves at the second-phase speed and where the first Z pulse is met is the home 
position.
