COUPOF during the motion
If synchronous mode is deselected while the spindles are in motion with COUPOF, the
following spindle continues to rotate at the current speed (n
read with system variable $AA_S in the NC parts program.
The following spindle can then be stopped from the parts program with M05, SPOS, SPOSA or
from the PLC with the appropriate interface signal.
COUPOFS with stop of following spindle
Another deactivation method for a synchronous spindle coupling, i.e. by stopping the
following spindle, has been added:
● Deactivating a coupling as quickly as possible and stop without specifying the position.
● Deactivating the coupling with stop of following spindle at the programmed position The
