Object 0x607C: Home offset  
This object is the difference between the zero position for the application and the 
machine home position (found during homing), measured in position units. During 
homing, the machine home position is found. Once homing is completed, the zero 
position is offset from the home position by adding the home offset to the home position. 
All subsequent absolute moves are taken relative to this new zero position, as illustrated 
in the following diagram.

  The zero position is determined after a successful homing sequence (home attain). 
Internal position limits are taken relative to the zero position point.
