Complete frame
The current complete frame $P_ACTFRAME results from the chaining of all active frames of
the frame chain:

Relative coordinate systems

Relative coordinate systems display the current setpoint positions of the axes which lie relative
to a specified reference point in the active displayed coordinate system. No programming can
be done regarding the relative coordinate systems. Only the axis positions in these systems
can be read via the system variables.
The new display coordinate systems lie relative to WCS and ENS coordinate system and result
through transformation of the WCS or ENS axis positions with the active system frame
$P_RELFRAME. The relative coordinate systems can not only be displaced linearly, but also
rotated, mirrored, compressed or expanded.
