Deactivate synchronous mode
Three different methods can be selected to deactivate synchronous mode:
1. COUPOF(FS, LS)
2. COUPOF(FS, LS, POS
3. COUPOF(FS, LS, POS
If continuous path control (G64) is programmed, a non-modal stop is generated internally in
the control.
Examples:
COUPDEF (S2, S1, 1.0, 1.0, "FINE, "DV")
:
COUPON (S2, S1, 150)
:
COUPOF (S2, S1, 0)
:
COUPDEL (S2, S1)
1. COUPOFS(FS, LS)
2. COUPOFS(FS, LS, POS

Fastest possible deactivation of synchronous operation. The block change is enabled
immediately.
Deselection of synchronous operation after deactivation position POS
crossed. Block change is not enabled until this position has been crossed.
Deselection of synchronous operation after the two deactivation positions POS
POS have been crossed. Block change is not enabled until both programmed positions
LS
have been crossed.

Deactivating a coupling with stop of the following spindle. Block change is performed as
quickly as possible with immediate block change.
After the programmed deactivation position that refers to the machine coordinate system
has been crossed, the block change is not enabled until the deactivation positions
POSFS have been crossed.
