4.1.5.3 Adjusting the machine zero proximity switch
This is helpful in some cases with machine reference modes that work with the MN
initiator and motor reference point.
If the motor reference point happens to coincide with the position of the MN
initiator, there is a possibility that small movements in the will cause the machine
reference point to shift by one motor revolution (to the next motor reference point).

2: Initiator level of the home switch
A solution to this problem is to move the MN initiator by means of software. This is
done using the value initiator adjustment.

1: machine reference offset.
The machine reference offset is used to determine the actual reference point for
positioning.
The rule for this is: Referene point = machine reference + machine reference offset
Note: if the machine reference initiator is located at the positive end of the travel
range, the machine reference offset must = 0 or be negative.
A change in the machine reference offset does not take effect until the next
machine reference run.
