Motion symbol in actual value window: The axes are still moving, i.e.
they are not within the exact stop window.
Displays the addresses of the existing axes with the machine axis
identifier (MCS) or with the geometric axis identifier (WCS).
(see also Section "Toggling between Machine/Workpiece Coordinate
System (MCS/WCS)")
Machine data are used to define whether the programmed frames are
to be calculated when displaying the WCS (settable zero system =
SZS display). Please refer to the information and specifications
provided by the machine manufacturer.
• If the axis identifier can only be displayed in an abbreviated form it
is replaced by the character *.
• If you traverse an axis in the positive (+) or negative (-) direction, a
plus or minus sign is shown in the relevant field.
The axis is in position if neither + nor – is displayed in the position
display.
The actual position of each configured axis in the machine (MCS) or
work (WCS) is displayed in these fields.
The sign is only displayed for negative values.
If the axes are traversed in the "Program interrupted" status in "Jog"
mode, the path traversed by every axis with respect to the point of
interruption is displayed in the REPOS offset.
Spindle window (if spindle is available)
Displays the set and actual value of the spindle speed, the position of
the spindle, the position of the spindle override switch
