Reset and recovery
Resetting the IS "Disable synchronization" (DB31, ... DBX31.5) has no effect 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 part program operation
COUPON (FS, LS, offset) with IS "Disable
synchronization" (DB31, ... DBX31.5) = 0.
COUPON (FS, LS, offset) can be written e.g. in an ASUB.
● By setting the IS "Resynchronize" (DB31, ... DBX31.4) = 1
