10.5.2.6 Chain operator
Frame components or complete frames can be combined into a complete frame using the chain operator ( : ).
10.5.2.7 Programmable axis identifiers
Geo, channel and machine axis identifiers can be used in the frame commands. The programmed axis must be
known to the channel-specific frames in the channel.
SPI
When programming frame instructions, the SPI(<spindle number>) axis function can be used in place of an
axis identifier.
SPI(<spindle number>) forms the reference of the spindle to the channel axis.
→ refer to MD35000 $MA_SPIND_ASSIGN_TO_MACHAX[ ] (assignment of spindle to machine axis)
The following frame instructions can be programmed with SPI(spino):
CTRANS()
CFINE()
CMIRROR()
CSCALE()
A spindle can only be assigned to one rotary axis at a time. The CROT(..) function can therefore not be
programmed withSPI(), as only geometry axes are permitted forCROT().
The channel axis identifier or machine axis identifier of the axis belonging to the spindle is always output when
decompiling frames, even when axis identifiers have been programmed in the part program with SPI(..).
If the spindle is assigned e.g., to the Channel Axis A then the programming:
N10 $P_UIFR[1] = CTRANS(SPI(1),33.33,X,1):CSCALE(SPI(1),33.33):CMIRROR(SPI(1))
during recompilation:
$P_UIFR[1]=CTRANS(X,1,A,33.33):CSCALE(A,33.33):CMIRROR(A)
If a spindle and an assigned axis are programmed in a frame instruction, then Alarm 16420 "Axis % multiply
programmed" is output.
Example:
$P_UIFR[1] = CTRANS(SPI(1),33.33,X,1,A,44)
(The spindle is assigned to Axis A.)
Programming examples
$P_PFRAME[SPI(1),TR]=22.22
$P_PFRAME=CTRANS(X, axis value,Y,axis value,SPI(1),axis value)
$P_PFRAME=CSCALE(X,Scale,Y,scale,SPI(2),scale)
$P_PFRAME=CMIRROR(S1,Y,Z)
$P_UBFR=CTRANS(A,10):CFINE(SPI(1),0.1)
