No.
B4 READY OUT: Trigger ready output
When TRIG. IN (A4) becomes acceptable (the laser radiation becomes ready), this output turns ON.
To turn on READY OUT, the following conditions are required:
• No error has occurred
• Laser pumping has completed
• Internal shutter is open
• The file number switching process has completed
• With the file using "rank function" or "external offset function", the data number and SET of I/O signals
have been input.
• When the file with the setting to use SIN command is selected, SIN command is transmitted by every
trigger input.
• When the serial communication control uses the command reception permission (MKM command), the
reception permission state is turned OFF.
B5 MARKING: Marking output
Output ON during marking (laser radiation).
If the marking time is shorter than the specified one-shot output time, MARKING OUT remains ON until the
one-shot output time ends.
B6 MARKING END: Marking end output
Output ON when the marking operation ended.
Even when the marking operation is interrupted due to the alarm, this MARK END turns ON.
This is one-shot output.
Reference
• READY OUT (B4) is output even during one-shot output of marking end output.
• MARK END (B6) is output even when marking is interrupted by the Emergency stop switch or laser stop input during
marking.
• Set the output time of the one-shot duration on the environment setting screen. The setting range is 2 to 510 ms. The
initial setting value is 40 ms. One-shot output time has a small margin of error for the setting value.

pumping.
The output turns ON approximately 15 to 20 seconds after the laser pumping started.
