YASNAC PCNC I/O Signal Function Manual Chapter 6: Operation Support Functions
6.4 Automatic Operation Start/Stop Input Signals and Running/Stopped Output Signals
(1) Automatic Operation Start Input Signal
By “closing” and the “opening” the ST input signal when the tape, memory, MDI or edit mode
is selected for PCNC operation, the PCNC starts automatic operation to execute a part pro-
gram. At the same time, it turns the running STL output signal ON.
Note that input of the ST signal is ignored in the following states:
• The PCNC is in an alarm state. (alarm output or input error signal is ON).
• Automatic operation stop “*SP” input is “opened”.
• External reset “ERS” input is “closed”.
• The RESET button on the operation panel is “closed”.
• Emergency stop “*ESP” is not closed.
• STL signal is output during automatic operation.
(2) Automatic Operation Stop Input Signal
After start of automatic operation, the PCNC completes automatic operation and turns the
automatic start (STL) output signal OFF when any of the following states is satisfied.
• In the MDI mode, execution of a part program is completed by the manually input data.
• Execution of one block of a part program is completed with the single-block (SBK) input
is “closed”.
• The end of a program (EOP) input is “closed” by the execution of an M command in a part
program.
(3) Running Output Signal
If the automatic operation stop input “SP” is “opened” during auomatic operation, axis move-
ment, etc. is interrupted and the running ouput signal “STL” is opened. Then, the stopped out-
put signal “SPL” is closed.
The input of automatic operation stop signal is ignored if it is input in the following state.
• While a thread cutting block is being executed.
Automatic Operation Start Input Signal ST #30030
Automatic Operation Stop Input Signal *SP #30031
Running Output Signal #35370
Stopped Output Signal #35371
