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
FS
). The current speed can be 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
Opening a synchronous spindle coupling is extended by a stop of the following spindle:
● Deactivating a coupling as quickly as possible and opening a coupling as quickly as
possible.
The block change is then enabled.
COUPOFS(FS, LS)
● Opening the coupling with stop of following spindle at the programmed position. The
block change is then enabled.
Condition:
COUPOFS(FS, LS) and COUPOFS(FS, LS, POS
FS
) have no meaning if a coupling was
active.
