Appendix D 14 Circumstance 1 Negative direction Start point Circumstance 2 Negative direction 14 Start point Circumstance 3 Start point Negative direction 14 Z pulse Home switch Negative limit switch Homing on the home switch, negative limit switch and Z pulse ( ○ 14 : mode 14) Mode 15 and mode 16 are reserved for future development. Mode 17~mode 30 Homing which has nothing to do with Z pulse In mode 17~mode 30 which are respectively similar to mode1~mode 14 mentioned previously, the axis has nothing to do with Z pulse but the relevant home switch and limit switch status while returning to the home position.
Mode 17 is similar to mode 1, mode 18 is similar to mode 2, mode 19 & mode 20 is similar to mode 3, mode 21 & mode 22 is similar to mode 5, mode 23 & mode 24 is similar to mode 7, mode 25 & mode 26 is similar to mode 9, mode 27 & mode 28 is similar to mode 11, and mode 29 & mode 30 are similar to 13. Take mode 19 and mode 21 for example: Mode 19 Circumstance 1: MC_Home instruction is executed and the axis moves in the positive 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 directly moves in the negative 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. D-12 DVP-MC operating manual
