D.1 Explanation of Homing Modes
DVP15MC11T provides many homing modes from which user can choose the appropriate one in accordance
with the field condition and technical requirement.

Mode 1 Homing which depends on the negative limit switch and Z pulse.
Circumstance 1
：
MC_Home instruction is executed when the negative limit switch is OFF and the axis
moves in the negative direction at the first-phase speed. 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 when the negative limit switch is ON and the axis
moves in the positive direction at the second-phase speed. Where the first Z pulse is
met is the home position when the negative limit switch is OFF.
