Using arithmetic parameters by the cycles
Multiple machining cycles (G60 through G65) and the machining canned cycles (G69, G81 to G89)
use the sixth nesting level of local parameters when they are active.
Machining canned cycles use the global parameter P299 for internal calculations and probing
canned cycles use global parameters P294 to P299.
Updating arithmetic parameter tables
The CNC will update the parameter table after processing the operations indicated in the block that
is in preparation. This operation is always done before executing the block and for this reason, the
values shown in the table do not necessarily have to correspond to the block being executed.
If the execution mode is abandoned after interrupting the execution of the program, the CNC will
update the parameter tables with values corresponding to the block that was being executed.
When accessing the local parameter and global parameter table, the value assigned to each
parameter may be expressed in decimal notation (4127.423) or in scientific notation (0.23476 E-3).
Arithmetic parameters in the subroutines
The CNC offers high level instructions for defining and using subroutines that may be called upon
from the main program (or a subroutine) and another subroutine from this one and so on, the CNC
limits the number of these calls to a maximum of 15 nesting levels. The CNC limitation is 20 nesting
levels.
Up to 26 (P0-P25) local parameters may be assigned to a subroutine. These parameters, that will
be unknown for blocks outside the subroutine, may be referred to by the blocks that make up the
subroutine.
Local parameters may be assigned to more than one subroutine up to 6 parameter nesting levels
within the 15 subroutine nesting levels.
