Appendix D Circumstance 1 Start point 5 Positive direction Circumstance 2 Start point Start point 5 Positive direction Circumstance 1 Negative direction Negative direction 6 Circumstance 2 6 Start point Z pulse Home switch Homing on the home switch and Z pulse ( : mode 5; : mode 6) Mode 7~ mode 10 Homing which depends on the home switch, positive limit switch and Z pulse Mode 7 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 motion direction changes 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 when 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 when the home switch is ON. Where the first Z pulse is met is the home position when the home switch is OFF. 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 ON. The axis starts to move at the second-phase speed when the home switch is ON.
Where moves at the first-phase speed when the home switch is OFF and the positive limit switch is the first Z pulse is met is the home position when the home switch is OFF. D-4 DVP-MC operating manual
