Example 2: Chaining of frames
Chaining of MEAFRAME for offsets
The MEAFRAME function returns an offset frame. If this offset frame is chained to the settable
frame $P_UIFR[1] that was active during the call of the function (e.g. G54), a settable frame is
provided for further conversions for the traversing or machining.
Chaining with ADDFRAME
If you want this offset frame in the frame chain to apply at a different position or if other frames
are active before the settable frame, the ADDFRAME function can be used for chaining into one
of the channel basic frames or a system frame.
The following must not be active in the frames:
● Mirroring with MIRROR
● Scaling with SCALE
The input parameters for the setpoints and actual values are the workpiece coordinates. These
coordinates must always be specified metrically or in inches (G71/G70) and radius-related
(DIAMOF) in the basic system of the control.
Additional information on ADDFRAME, see Function Manual Basic Functions.
3.8.8

Global frames

There is only one set of global frames for all channels on each control. Global frames can be
read and written from all channels. The global frames are activated in the respective channel.
Channel axes and machine axes with offsets can be scaled and mirrored by means of global
frames.
