The fine component is transferred on saving the programmable frame in a local frame variable (LUD or GUD) and
on rewriting.
The table below shows the effect of various program commands on the absolute and additive translation.
10.5.5.7 Channelspecific system frames
Channelspecific system frames
System frames are only described by system functions, such as PRESET, scratching, zero offset external and
oblique processing. There are up to seven system frames per channel.
The valid system frames in the channel can be defined via machine data:
MD28082 $MC_MM_SYSTEM_FRAME_MASK (System frames SRAM)
Only system frames required for system functions should be configured, in the interests of memory space. Per
channel, each system frame occupies approx. 1 KB SRAM und approx. 6 KB DRAM. The system frame for
PRESET and scratching and the system frame for cycles are the default. Channel-specific system frames are
configured as bit codes, in accordance with the table below:
