Measuring procedures
• Block search
Synchronized actions found during a block
search Block searchare collected and evaluated
on NC Start; the associated actions are then
started if necessary.
Static synchronized actions are active during
block search.
If polynomial coefficients programmed with
FCTDEF are found during a block search, they
are written directly to the setting data.
• Program interruption by asynchronized
subroutine
ASUP start:
Modal and static motion-synchronized actions
remain active and are also active in the
asynchronized subroutine.

Response following end of program
Modal and non-modal
M30 is delayed until the axis/spindle is
stationary.
End of program:
$MA_SPIND_ACTIVE_AFTER_RESET==1:
Spindle remains active
$MA_SPIND_ACTIVE_AFTER_RESET==0:
Spindle is stopped
Spindle remains active following a change in
operating mode
$MC_RESET_MODE_MASK, Bit13 == 1:
Leading value coupling remains active
$MC_RESET_MODE_MASK, Bit13 == 0:
Leading value coupling is disconnected
Measurements started from synchronized
actions are cancelled.
10.7 Supplementary conditions
are reset
Motion-Synchronous Action
Static (IDS)
remain active
Movement continues
Spindle remains active
A coupling started from a static
synchronized action remains
Measurements started from
static synchronized actions
remain active.
