Appendix D Circumstance 1 Start point Negative direction 2 Circumstance 2 Negative direction 2 Start point Z pulse Positive limit switch Homing on the positive limit switch and Z pulse ( : mode 2) Mode 3 and mode 4 Homing which depends on the home switch and Z pulse Mode 3 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 axis encounters that 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 directly 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 while the home switch is OFF. Mode 4 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 axis encounters that the home switch is ON. 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 axis encounters that the home switch is OFF. Where the first Z pulse is met is the home position. D-2 DVP-MC operating manual
