D.1 Explanation of Homing Modes
DVP-15MC series motion controller 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.
