Specification Of Memory Type; Programming - Siemens SINUMERIK 840D sl Function Manual

Note
In the case of a curve table that contains segments without leading axis movement (this
means that the following axis jumps at this point), the following axis can only make a jump
within its dynamic limits (max. velocity and max. acceleration). This means that there is
always a deviation from the programmed curve.

Specification of memory type

MD20905
If there is no memory specification while defining or deleting a curve table, the memory type
can be determined through the following machine data:
MD20905 $MC_CTAB_DEFAULT_MEMORY_TYPE (default memory type for curve tables)

Programming

Definition
The following modal language commands work with curve tables: (The parameters are
explained at the end of the list of functions.)
• Beginning of definition of a curve table:
CTABDEF(following axis, leading axis, n, applim, memType)
• End of definition of a curve table:
CTABEND()

Description
No curve tables that contain a discontinuity in the following axis are produced. Alarm 10949 is
output and program processing is aborted.
Curve tables with a discontinuity in the following axis can be generated. If a segment contains
a discontinuity in the following axis, Alarm 10955 is output but program processing is
continued.
Curve tables with a discontinuity in the following axis can be created without an alarm being
output.
Description
Curve tabels are normally created in the static NC memory.
Curve tabels are normally created in the dynamic NC memory.
