5.3.3 Single block
General The single block operation is valid in automatic operation mode (Auto mode).
When the single block signal (SBK) is set to 1 during automatic operation, the CNC
enters the automatic operation stop state after executing the current block. In
subsequent automatic operation, the CNC enters the automatic operation stop state
after executing each block in the program. When the single block signal (SBK) is set
to 0, normal automatic operaion is stored.
