Test marking
mode
(1)
“0”: Marking energy error detection
“1”: Marking energy error not
detected
Performs test marking upon command
reception.
Set whether to detect the marking energy error
after test marking.
This setting is omissible. If this is omitted, “0”:
marking energy error is indicated.
Marking energy 9 “000000000”–“999999999” [mJ]
Marking time 6
• Marking time 100 seconds or
more: “0100.0”–“9999.9” [s]
• Marking time less than 100
seconds: “000.01”–“099.99” [s]
When the marking time is 100 seconds or more,
the number of decimal places should be 1 and
when it is less than 100, it should be 2.
Reference
• When the test marking is performed, the marking operation is started by actual laser radiation.
• For test marking, the counter value is not changed even when a counter is set.
• This command is not acceptable when the No. 2 DIP switch on the back surface of controller is turned to OFF.
• This command can be transmitted when laser pumping is turned ON and the shutter is closed. Response data for
abnormal receiving (NAK03 or NAK99) is returned when the laser pumping is OFF or the shutter is opened. Even when
the “reception mode ON” is set for the command reception permission: MKM command, it is refused if the shutter is
opened.
• When the Marking Status Sending Enable (MST/MKR) is set to on, the marking status is transmitted after the marking is
completed.
• Transmit the test marking result readout command after the marking end output of the output terminal is turned
ON following the test marking execution command, or after response to the marking status if the “Marking Status
Transmission Permission (MST Command)” is set.
• For LP-Mxxx-S type, laser can not be emitted without opening the laser gate. After starting the test marking, open the
laser gate by external control signals. Refer to the “Safety / Setup / Maintenance Guide” for detail.
• For LP-Mxxx-S type, “laser gate open request output” signal will be ON to start the test marking and “laser gate close
request output” signal will be ON after finishing the marking for the specified one-shot time.
