1.4.3 Actual value window
The actual values of the axes and their positions are displayed.
Work/Machine
The displayed coordinates are based on either the machine coordinate system or the
workpiece coordinate system. The machine coordinate system (Machine), in contrast to the
workpiece coordinate system (Work), does not take any work offsets into consideration.
You can use the "Machine actual values" softkey to toggle between the machine coordinate
system and the workpiece coordinate system.
The actual value display of the positions can also refer to the SZS coordinate system
(settable zero system). However the positions are still output in the Work.
The ENS coordinate system corresponds to the Work coordinate system, reduced by certain
components ($P_TRAFRAME, $P_PFRAME, $P_ISO4FRAME, $P_CYCFRAME), which are
set by the system when machining and are then reset again. By using the ENS coordinate
system, jumps into the actual value display are avoided, that would otherwise be caused by
the additional components.
