S3: Synchronous spindle
13.1 Brief description
2. User-defined coupling:
IS "Following spindle active" (DB31, ... DBX99.1) and IS "Leading spindle active" (DB31, ...
DBX99.0) indicate to the PLC for each machine axis whether the axis is active as a leading
or following spindle.
The LS can be programmed either via a part program, PLC or also using synchronized
actions.
Transformation ratio
The transformation ratio is programmed with separate numerical values for numerator and
denominator (transformation ratio parameters). It is therefore possible to specify the
transformation ratio very exactly, even with rational numbers.
In general:
k = transformation ratio parameter for numerator Transformation ratio parameters for
Ü
denominator = Ü
The value range of the transformation ratio parameter (Ü
unlimited in the control.
The transformation ratio parameters for the coupling configured via machine data can be
defined in channel-specific SD42300: COUPLE_RATIO_1[n]. In addition, the transformation
ratio can be altered with language command
values entered in the setting data is not overwritten in this case (default settings).
The transformation ratio for the coupling defined via the NC part program can only be input
with language command
The new transformation ratio parameters take effect as soon as the
been processed.
For further programming commands for synchronous spindle couplings, please see
"Programming of synchronous spindle couplings" Section .

Couplings can be created and altered in the NC part program with language command
" (FS, LS, ...)". If a new coupling relationship is to be defined, it may be necessary
COUPDEF
to delete an existing user-defined coupling beforehand (with language command
(FS, LS)).
COUPDEL
The axis names (Sn, SPI(n)) for the following and leading spindles must be programmed
with FS and LS for every language command COUP..., thus ensuring that the
synchronous spindle coupling is unambiguously defined.
The valid spindle number must then be assigned axis-specific machine data of a machine
axis:
