Define synchronized spindle pair: Options
Fixed definition of coupling:
The leading and following spindle are defined in
machine data.
With this coupling, the machine axes defined for the
LS and FS cannot be changed from the NC part
program. The coupling can nevertheless be
parameterized in the NC part program by means of
COUPDEF (on condition that no write protection is
valid).
User-defined coupling:
The language instruction COUPDEF can be used to
create new couplings and change existing ones in
the NC part programs. If a new coupling relationship
is to be defined, any existing user-defined coupling
must be deleted with COUPDEL.
Define new coupling COUPDEF
The following paragraphs define the parameters for
the predefined subroutine:
COUPDEF (FS,LS,SR
FS
,SR
LS
, block change beh.,
coupling)
Following and leading spindles: FS and LS
The axis names FS and LS are used to identify the
coupling uniquely.
They must be programmed for each COUP
statement. Further coupling parameters only need to
be defined if they are to be changed (modal scope).
Example:
N… COUPDEF(S2,S1,Ü
FS
,Ü
LS
)
Meaning:
S2 = following spindle, S1 = leading spindle
