10.5 Frames
Example
TRANS X10 Y10 Z10
ATRANS X5 Y5
G58 X20
G59 X10 Y10
G58 and G59 can only be used if:
MD24000 $MC_FRAME_ADD_COMPONENTS (frame components for G58 / G59) == TRUE
The table below shows the effect of various program commands on the absolute and additive
translation.

CTRANS()
CFINE(X,10)
$P_PFRAME[X,TR] = 10
$P_PFRAME[X,FI] = 10

Channelspecific system frames

Channel-specific system frames are only written by system functions, such as actual value
setting, scratching, external work offset and inclined machining.
Machine data
Parameterization of the channel-specific system frames
Only channel-specific system frames whose system functions are actually used should be
configured for memory space reasons.
Per channel, each system frame occupies approx. 1 KB static and approx. 6 KB dynamic
memory.
The channel-specific system frames are parameterized in the following machine data:
MD28082 $MC_MM_SYSTEM_FRAME_MASK, bit<n>

Value System frame available:
1 $P_SETFR: Actual value setting and scratching
1 $P_EXTFR: External work offset via system frames
1 $P_PARTFR: TCARR and PAROT with an orientable toolholder
1 $P_TOOLFR: TOROT and TOFRAME
1 $P_WPFR: Frame for workpiece reference points
1 $P_CYCFR: Frame for cycles
