S3: Synchronous spindle
14.2 Programming of synchronous spindle couplings
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
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)

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.
