2.5.2  Use of workpiece-related actual-value system 
Requirements, basic settings 
The settings described in the previous Section have been made for the system.  
The predefined setting after power-up of the MMC is MCS. 
Switchover to WCS 
The change to the WCS via the user interface causes the axis positions relative to the origin 
of the WCS to be displayed. 
Switchover to MCS 
The change to the MCS via the user interface causes the axis positions relative to the origin 
of the MCS to be displayed. 
Interrelationships between coordinate systems 
The figure below shows the interrelationships between the machine coordinate system 
(MCS) and the workpiece coordinate system (WCS).
