4.3.3.4 Object 607C
h
: Home Offset
This object indicates the configured difference between the zero position for the application and the
machine home position/home switch (found during homing). While homing, the machine home position
is found and once the homing is completed, the zero position is offset from the home position by
adding the home offset to the home position. The effect of setting the home position to a non-zero
value depends on the selected homing method. The value of this object is given in microsteps. Negative
values indicate the opposite direction.
