Appendix D Circumstance 1 Start point Negative direction 19 Circumstance 2 Negative direction 19 Start point Home switch Homing on the home switch ( ○ 19 : mode 19) Mode 21 Circumstance 1: MC_Home instruction is executed and the axis moves in the negative direction at the first-phase speed while the home switch is OFF. The motion direction changes and the axis moves at the second-phase speed once the home switch becomes ON. And where the axis stands is the home position at the moment the home switch becomes OFF. Circumstance 2: MC_Home instruction is executed and the axis moves in the positive direction at the second-phase speed while the home switch is ON.
And where the axis stands is the home position at the moment the home switch becomes OFF. Circumstance 1 Start point 21 Positive direction Circumstance 2 Start point 21 Positive direction Home switch Homing on the home switch ( ○ 21 : mode 21) Mode 31 and mode 32 Reserved for future development. Mode 33 ~ mode 34 Homing which depends on Z pulse direction. And the place where the axis stands is the home position once the first Z pulse is met. In mode 33, MC_Home instruction is executed and the axis moves at the second-phase speed in the negative In mode 34, MC_Home instruction is executed and the axis moves at the second-phase speed in the positive direction.
And the place where the axis stands is the home position once the first Z pulse is met. DVP-MC operating manual D-13
