Appendix D Appendix D Explanation of Homing Modes with on-site condition and technical requirement. DVP10MC11T provides many homing modes from which user can choose the appropriate one in accordance Mode 1 Homing which depends on the negative limit switch and Z pulse. Circumstance 1: MC_Home instruction is executed and the axis moves in the negative direction at the first-phase speed when the negative limit switch is OFF. The motion direction changes and the axis moves at the second-phase speed when the axis encounters that the negative limit switch is ON. Where the first Z pulse is met is the home position when the negative limit switch is OFF. Circumstance 2:
MC_Home instruction is executed and the axis moves in the positive direction at the second-phase speed when the negative limit switch is ON. Where the first Z pulse is met is the home position when the negative limit switch is OFF. Circumstance 1 Start point 1 Positive direction Start point Circumstance 2 1 Positive direction Z pulse Negative limit switch Homing on the negative limit switch and Z pulse ( : mode 1) Mode 2 Homing which depends on the positive limit switch and Z pulse Circumstance 1: MC_Home instruction is executed and the axis moves in the positive direction at the first-phase speed when the positive limit switch is OFF.
The motion direction changes and the axis moves at the second-phase speed when the axis encounters that the positive limit switch is ON. Where the first Z pulse is met is the home position while the positive limit 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 positive limit switch is ON. Where the first Z pulse is met is the home position while the positive limit switch is OFF. DVP-MC operating manual D-1
