Appendix D Circumstance 1 Negative direction 12 Start point Circumstance 2 Start point Negative direction 12 Circumstance 3 Start point Negative direction 12 Z pulse Home switch Negative limit switch Homing on the home switch, negative limit switch and Z pulse ( ○ 12 : mode 12) Mode 13 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 while the home switch is ON. The motion direction changes and the axis moves at the second-phase speed while the home switch is OFF. 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 while the home switch is ON. The motion direction changes and the axis moves at the second-phase speed while 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 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 and where the first Z pulse is met is the home position when the home switch is ON. D-10 DVP-MC operating manual
