5. AUTOMATIC OPERATION
289
Single block operation is valid only for automatic operation.
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
operation is restored.
Single block operation during the execution of custom macro statements
depends on the setting of bit 5 (SBM) of parameter No. 6000, as follows:
SBM = 0, SBV = 0: Operation does not stop in the custom macro
statements but stops once the next NC command
has been executed.
SBM = 1: Operation stops after each block in the custom macro
statements.
SBV = 1: Single block operation in custom macro statements is
suppressed using macro system variable #3003. Execution
of custom macro statements is stopped after block
execution.
When the CNC is in the automatic operation stop state during single block
operation, the mode can be changed to manual data input (MDI), manual
handle feed (HNDL), incremental feed (INC), or jog feed (JOG), by using
the mode select signals (MD1, MD2, and MD4).
[Classification] Input signal
[Function] Enables single block operation.
[Operation] When this signal is set to 1, single block operation is performed. When
this signal is set to 0, normal operation is performed.
[Classification] Output signal
[Function] Notifies the PMC of the state of the single block signal.
[Output condition] This signal is set to 1 in the following case:
– When single block signal SBK is set to 1
This signal is set to 0 in the following case:
– When single block signal SBK is set to 0
