Formatting and Interpreting Data Blocks

If you issue a slide stop command before the next move command, so that
the axis is stopped when you issue the next move command, the servo
positioning assembly starts execution of the next move without
completing execution of the current move.
If you issue the next move command at a time when the axis cannot
decelerate at the programmed rate without passing the endpoint of the
next move, the servo positioning assembly executes a slide stop that
carries the axis past the next move endpoint, then moves the axis in the
opposite direction to the desired endpoint.
If no data for a next move is available when you issue a next move
command, the 1771-M3 controller sets the insufficient data bit in the
status block, and performs a slide stop if the axis is in motion.
