YASNAC PCNC I/O Signal Function Manual Chapter 6: Operation Support Functions
6.5 Single-Block Input Signal
This input signal is used to execute a part program block by block in automatic operation.
When the PCNC is in the automatic mode with SBK input signal “closed”, if automatic operation
is started, the PCNC executes one block of a part program and stops, the closes the STL (running,
#35370) output signal.
If the SBK input signal is “closed” during the execution of a part program, the PCNC stops after
the completion of the block presently being executed.
6.6 Manual Absolute Input Signal
(1) When the Absolute Input Signal is “Open”
Tool path of a part program executed continuously in automatic mode after manual interrup-
tion of axis movement is shifted by the manually moved distance.
