COUPOF variants
Three different methods can be used to deselect synchronous mode with COUPOF:
1. Deactivation of coupling as quickly as possible
2. A coupling is not deselected until the following spindle has crossed the programmed
3. A coupling is not deselected until the following spindle and leading spindle has crossed

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 part program.
The following spindle can then be stopped from the part program with M05, SPOS, SPOSA or
from the PLC with the appropriate interface signal.

Note
If the LS and/or FS is in axis mode before switching off the synchronous coupling, the
axis mode is left with use of the spindle identifier and the speed control mode is activated.
If the spindle is switched off with use of the axis identifier, no changeover takes place.
Before shutdown, the LS must be in the setpoint-side standstill.
