Synchronous Spindles (S3)
Programming of synchronous spindle couplings
14.2.2 Programming instructions for activating and deactivating the coupling
Activate synchronous mode
Language instruction COUPON is used to activate couplings and synchronous mode.
Two methods by which synchronous operation can be activated are available:
1. COUPON(FS, LS)
2. COUPON(FS, LS, POS
3. COUPONC(FS, LS)
By programming COUPON(FS, LS, POS
active, the angular offset between LS and FS can be changed.
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

Fastest possible activation of synchronous operation with any angular reference between
the leading and following spindles.
Activation of synchronous operation with a defined angular offset POS
leading and following spindles. This offset is referred to the zero degrees position of the
leading spindle in a positive direction of rotation. The block change is enabled according
to the defined setting. Range of POS
When activating with COUPONC, the previous programming of M3 S... or M4 S... is
adopted. A difference in speed is transferred immediately. An offset position cannot be
programmed.
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.
