Coupling options
Synchronous spindle couplings can be defined as
● Permanently configured via channel-specific machine data
● Freely defined using language commands (COUP...) in the part program
. The following variants are possible:
1. A fixed configuration for a coupling can be programmed via machine data. In addition, a
2. No coupling is configured via machine data. In this case, the couplings can be user-
Separate following spindle interpolator
The separate following spindle interpolator allows a number of following spindles from
different channels or from another NCU to be coupled as defined by the user to a single
leading spindle. The following spindle interpolator is

Certain synchronous spindle functions can be controlled from the PLC by means of coupling-
specific axial VDI interface signals. These signals act exclusively on the slave spindles and
do not affect the leading spindle (see Section "Controlling synchronous spindle coupling via
PLC (Page 716)").
Definition of synchronous spindles
Before synchronous operation is activated, the spindles to be coupled (FS, LS) must be
defined.
This can be done in two ways depending on the application in question:
1. Permanently configured coupling:

Machine axes that are to function as the following spindle (FS) and leading spindle (LS)
are defined in channel-specific MD 21300 $MC_COUPLE_AXIS_1[n].
The machine axes programmed as the LS and FS for this coupling configuration cannot
be altered by the NC part program.
If necessary, the coupling parameters can be modified with the NC part program.
