Appendix D 8 Circumstance 1 Start point Positive direction Circumstance 2 Start point 8 Positive direction Circumstance 3 Start point 8 Positive direction Z pulse Home switch Positive limit switch Homing on the home switch, positive limit switch and Z pulse ( : mode 8) Mode 9 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. 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 2:
MC_Home instruction is executed and the axis moves in the positive 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 moves at the second-phase speed and where the first Z pulse is met is the home position when the home switch is ON.
