The Compax3 machine zero modes are adapted to the CANopen profile for Motion
Control CiADS402.
Essentially, you can select between operation with or without machine reference.
The reference point for positioning is determined by using the machine reference
and the machine reference offset.
Machine reference run
In a homing run the drive normally moves to the position value 0 immediately after
finding the home switch. The position value 0 is defined via the homing offset.
A machine reference run is required each time after turning on the system for
operation with machine reference.
Please note:
During homing run the software end limits are not monitored.

1: machine zero point
The machine reference offset is used to determine the actual reference point for
positioning.
The rule for this is: Machine zero point = - Machine zero Offset
A change in the machine reference offset does not take effect until the next
machine reference run.
