Programmed coupling
Defining a coupling:
COUPDEF(FS, ...)
Activation of a coupling: COUPON(FS, LS, POS
Activate and transfer a movement for coupling difference in speed:
COUPONC(FS, LS)
Deactivation of a coupling: COUPOF(FS, LS, POS
with stop of following spindle: COUPOFS(FS, LS, POS
Deleting the coupling data: COUPDEL
(FS, LS)
Reduced specification without the main spindle
Without specifying a leading axis, the the following language instructions are permitted:
COUPOF(FS), COUPOFS(FS), COUPDEL(FS), COUPRES(FS).
Note
The FS and LS must be programmed for each COUPDEF, COUPON and COUPONC instruction
so that alarm messages are not triggered.

14.2.1 Preparatory programming instructions
Programmable couplings
The number of couplings can be programmed as often as desired depending on the axes
available. This number results from the number of axes/spindles less one for the master.
Furthermore, one coupling can also be configured via machine data as in earlier SW
versions.
Permanently configured coupling
The coupling characteristics and speed ratio for a permanently configured synchronous
spindle coupling can be altered by the NC part program provided that they are not write-
protected. The machine axes for LS and FS cannot be changed.
