Appendix D Circumstance 1 Start point Negative direction 7 Circumstance 2 Negative direction Start point Circumstance 3 Start point Negative direction 7 Z pulse Home switch Homing on the home switch, positive limit switch and Z pulse ( : mode 7) Positive limit switch Mode 8 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 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. 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.
The motion direction changes and the axis moves at the second-phase speed when 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 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 still moves at the first-phase speed when the home switch is ON. The motion direction changes and the axis moves at the first-phase speed when the home switch is OFF.
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. DVP-MC operating manual D-5 7
