3. Activate coupling with following spindle stationary with COUPON
N05 SPOS=10 SPOS[2]=20
N15 COUPDEF (S2, S1, 1)
N20 COUPON (S2, S1)
N10 G4 F1
4. Activate coupling with following spindle stationary with COUPONC
Positioning or axis mode
If the following spindle is in positioning or axis mode before coupling, then the following
spindle behaves the same for COUPON(FS, LS) and COUPONC(FS, LS).
Define synchronized spindle pair
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 parts program.
The coupling can nevertheless be parameterized in the NC parts program by means of
COUPDEF (on condition that no write protection is valid).
User-defined coupling:
The statement COUPDEF can be used to create new couplings and change existing ones in
the NC parts programs. If a new coupling relationship is to be defined, any existing user-
defined coupling must be deleted with COUPDEL.
Define a new coupling COUPDEF
The following paragraphs define the parameters for the predefined subroutine:
COUPDEF(FS, LS, T
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, T
Meaning:
S2 = following spindle, S1 = leading spindle
