A.4 Explanation of DMC_Home_P
DFB_Home_P 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 run 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 run 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.
Mode 2: Homing which depends on the positive limit switch and Z pulse
Circumstance 1: MC_Home instruction is run when the positive limit switch is OFF and the axis moves in the positive 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 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 run when the positive limit switch is ON and the axis moves in the negative direction at
the second-phase speed. Where the first Z pulse is met is the home position while the positive limit switch is
OFF.
