2.4.5.6 Programmable frame $P_PFRAME
Programmable frames are available only as active frames.
This frame is reserved for the programmer.
The programmable frame can be maintained with the machine data:
MD24010 $MC_PFRAME_RESET_MODE = 1 ("Reset mode for programmable frame")
during RESET.
This functionality is important, most of all if after a RESET one still wants to retract out of an
oblique hole.
MIRROR
Mirrorings of a geometry axis were thus far (up to SW-P4) related to a defined reference axis
only using the machine data:
MD10610 $MN_MIRROR_REF_AX ("reference axis for the mirroring")
.
From the user's point of view, this definition is hard to follow. When mirroring the z axis, the
display showed that the x axis was mirrored and the y axis had been rotated about 180
degrees. When mirroring two axes this became even more complex and it was no longer
easy to understand, which axes had been mirrored and, which had not.
With SW P5 and higher, there is the option to clearly display the mirroring of an axis. A
mirroring is then not mapped to the mirroring of a reference axis and rotation of other axes.
This setting can be configured through the machine data setting:
MD10610 $MN_MIRROR_REF_AX = 0.
MIRROR and AMIRROR are used to expand the programming of the programmable frame.
Previously, the specified value of the coordinate axis, e.g., the value 0 for MIRROR X0, is not
evaluated, but the AMIRROR has a toggle function, i.e., MIRROR X0 activates the mirror and
a further AMIRROR X0 deactivates it. MIRROR always has an absolute effect and AMIRROR
an additive effect.
The
MD10612 $MN_MIRROR_TOGGLE = 0 ("Mirror Toggle")
machine data setting can be used to define that the programmed values are evaluated.
A value of 0, as inAMIRROR X0, deactivates the mirroring of the axis, and values not equal
to 0 cause the axis to be mirrored if it is not already mirrored.
It is possible to read or write mirrors component by component independent of machine data
MD10612 $MN_MIRROR_TOGGLE.
A value = 0 means that the axis is not mirrored and a value = 1 means that the axis will
always be mirrored, irrespective of whether it has already been mirrored or not.
$P_NCBFR[0,x,mi] = 1
; x axis is always mirrored.
$P_NCBFR[0,x,mi] = 0
; x axis mirror is OFF.
