The program advances to the next block if the end of motion criteria for the spindle or axes programmed in the current block
plus the block change criterion for path interpolation are fulfilled.
Synchronization
In order to synchronize spindle movements,
Conditions
The spindle to be positioned must be capable of operation in position-controlled mode.
