Mirroring 
You can set the axis, about which mirroring is performed, via  
MD10610 MIRROR_REF_AX:  
 
MD10610 = 0:  Mirroring is performed around the programmed axis. 
MD10610 = 1 or 2 or 3:  Depending on the input value, mirroring is mapped onto the 
mirroring of a specific reference axis and rotation of two other 
geometry axes. 
Frame chaining 
The current FRAME is composed of the total basic frame, the settable FRAME, the 4 system 
frames and the programmable FRAME. 
The current complete frame is calculated according to the formula below: 
 
$P_ACTFRAME =  $P_SETFRAME : $P_EXTFRAME : $P_PARTFRAME : 
$P_ACTBFRAME : $P_IFRAME : $P_TOOLFRAME : 
$P_PFRAME 
Frames with G91  
Incremental programming with G91 is defined such that the compensation value is traversed 
additively to the incrementally programmed value when a zero offset is selected. 
The following are set via the setting data:  
SD42440 FRAME_OFFSET_INCR_PROG 
 
Value = 1  Zero offset is applied on FRAME and incremental programming of 
an axis (= default setting). 
Value = 0  Only the programmed path is traversed. 
Suppression of frames 
Current frames can be suppressed with the following instructions: 
 
G53 
Current zero offset (ZO) 
G153 
Current frame, incl. basic frame 
SUPA 
Current ZO, incl. programmed offsets 
NCU global basic frames 
For rotary indexing machine technology, for example, a channel must be used to define 
frames for other channels. These cross-channel frames are shown in the "NCU global basic 
frames" below.
