Overview

Definition
The term "workpiece-related actual-value system" designates a series of functions that permit the user:
• To use a workpiece coordinate system defined in machine data after power­up.
Features:
- No additional operations are necessary.
- Effective in JOG and AUTOMATIC modes
• To retain the valid settings for the following after end of program for the next part program:
- Active plane
- Settable frame (G54-G57)
- Kinematic transformation
- Active tool offset
• To change between work coordinate system and machine coordinate system via the user interface.
• To change the work coordinate system by operator action (e.g., changing the settable frame or the tool
offset).
10.6.2 Use of workpiece­related 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 HMI software 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.
