Basic frame and settable frame are effective after Reset if MD 20110 RESET_MODE_MASK
is set as follows:
Bit0=1, bit14=1 -->
Bit0=1, bit5=1 -->
Predefined settable frames $P_UBFR
The basic frame is programmed with $P_UBFR, but it is not simultaneously active in the part
program. The basic frame programmed with $P_UBFR is included in the calculation if
● Reset was activated and bits 0 and 14 are set in MD RESET_MODE_MASK and
● The statements
Predefined settable frames $P_UIFR[n]
The predefined frame variable $P_UIFR[n] can be used to read or write the settable zero
offsets
These variables produce a one-dimensional array of type FRAME called
Assignment to G commands
As standard, five settable frames
–
G500
Note
Frame variables must be programmed in a separate NC block in the NC program. Exception:
Programming of a settable frame with
$P_IFRAME=$P_UIFR[0]
$P_IFRAME=$P_UIFR[1]
$P_IFRAME=$P_UIFR[2]
$P_IFRAME=$P_UIFR[3]
$P_IFRAME=$P_UIFR[4]
You can change the number of frames with machine data:
$P_IFRAME=$P_UIFR[5]
... ... ...
$P_IFRAME=$P_UIFR[99]
Note
This allows you to generate up to 100 coordinate systems which can be called up globally in
different programs, for example, as zero point for various fixtures.
