8.13 Behavior during block search
This affects the groups of auxiliary functions for any spindle configured in the system, whereby
the spindle number corresponds to an auxiliary function's address extension.
Group a:
Group b:
Group c:
Deleting obsolete auxiliary functions
In the functions below, the auxiliary functions from group a are deleted for the spindle
concerned:
● For the following spindle when a generic coupling, such as COUPON, TRAILON, EGON,
etc. is switched on
Generating implicit auxiliary functions from group a
In the functions below, the auxiliary functions from group a are generated implicitly for the
spindle concerned:
● For the following spindle when the synchronous spindle coupling is switched off
– COUPOF generates M3, M4 and S or M5 in the main run depending on the coupling
– COUPOF(S<n>, S<m>, POS) and COUPOFS(S<n>, S<m>, POS, POS) generate M3,
– COUPOFS generates M5 in the main run.
– COUPOFS(S<n>, S<m>, POS) generates M19 in the main run.
● M70 is generated during a traversing motion as an axis or during the transition to axis mode
by selecting a transformation during which the spindle enters as an axis.
● M5 is generated during SPCOF.
Note
Within the context of the "axis interchange" and "axis container rotation" functions, the auxiliary
functions for programming the spindle must always be specified in a way which ensures
compatibility with the actual (motor) state during interchange/rotation. A distinction is made
here between the axis interchange and axis container mechanisms.
Example of axis container rotation:
An axis container has four spindles, each assigned to a separate channel (1 - 4). M3 S1000
is always programmed in channel 1, and an axis container rotation is then executed. The other
channels do not perform any spindle programming. Following the third axis container rotation
and the fourth spindle programming, M3, all four spindles rotate clockwise at a speed of 1,000
rpm. If the end of the SERUPRO now lies within this range, every ASUB for a channel is
expected to contain an M3 S1000 for the local spindle.
During interchange however, the collected auxiliary functions may only be assigned to the
channel where the spindle is currently located.

The implicit M19 ("SPOS[<address extension>] = IC(0)" in the ASUB) activates the
positioning mode without a traversing motion.
