Reset and recovery
Resetting the IS "Disable synchronization" (DB31, ... DBX31.5) has no impact on the
following spindle offset. If the offset motion of the following spindle has been suppressed by
the VDI interface signal, then the offset is not automatically applied when the VDI signal is
reset.
Synchronization is recovered as follows:
● By repeating the parts program instruction COUPON (FS, LS, offset) with IS "Disable
● By setting the IS "Resynchronize" (DB31, ... DBX31.4) = 1

synchronization" (DB31, ... DBX31.5) = 0.
COUPON (FS, LS, offset) can be written e.g. in an ASUB.
Synchronous Spindles (S3)
; IS "Disable synchronization"
; Set (DB31, ... DBX31.5) = 1 for S2
; Positions correspond to an offset of 0°
; Actual offset of 0 degrees is retained
; no following spindle movement,
; VDI signals
; IS "Synchronism coarse"
; Set (DB31, ... DBX98.1) and
; IS "Synchronism fine"
; Set (DB31, ... DBX98.0)
; are set and the block change
; is enabled.
