Detailed description
2.4 Frames
Parameterization
Frame suppressions SUPA, G153 and G53 lead to the WCS, SZS and possibly the BZS
jumping when frame suppression is active. This characteristic for position display and pre-
defined position variables can be changed through the following machine data:
MD24020 $MC_FRAME_SUPPRESS_MODE (Positions during frame suppression)
Bit
0
1
When the bit is set, the position for the display or the variables is calculated without frame
suppression so that no further jumps in the position occur.
70
Significance
Positions for display (BTSS) are without frame suppression.
Position variables are without frame suppression.
Basic logic functions: Axes, coordinate systems, frames (K2)
