Appendix D Circumstance 1 Start point 13 Positive direction Circumstance 2 Start point 13 Positive direction Circumstance 3 Start point 13 Positive direction Z pulse Home switch Negative limit switch Homing on the home switch, negative limit switch and Z pulse ( ○ 13 : mode 13) Mode 14 Circumstance 1: 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 axis moves at the second-phase speed once 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 negative direction at the second-phase speed while the home switch is ON. 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 motion direction changes again 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 while the home switch is OFF.
