No. Name and description
X6 LASER SUPPLY IN: Laser pumping input
While this input is turned on, the laser is pumped to enable the radiation.
It takes approximately 7 seconds from turning on LASER SUPPLY IN to completion of laser pumping.
This terminal is available when the laser pumping control method is set to I/O at the system settings of Laser
Marker NAVI smart.
X7 TARGET DETECTION IN
Connect a sensor which detect the work piece is in position for lasing.
According to the ON/OFF state of this terminal, CHECK OK OUT (No.34) or CHECK NG OUT (No.35) of I/O
connector turns on for one-shot pulse duration after the trigger processing (lasing) operation.
• When TARGET DETECTION IN (X7) turns ON for more than 1ms during lasing operation: CHECK OK
OUT (No.34) turns ON.
• When TARGET DETECTION IN (X7) did not turn ON during lasing operation: CHECK NG OUT (No.35)
turns ON.
This terminal is available when TARGET DETECTION IN (X7) is set to "Enabled" at the system settings of
Laser Marker NAVI smart.
• TARGET DETECTION IN is not available when you use the link control with an image checker.
X8 SHUTTER IN: Shutter open input
While this input is turned on, the internal shutter opens. The control of this terminal is enabled when
SHUTTER ENABLE IN (X9) is ON.
There is a delay time of around 200ms to max. 1 second from turning ON/OFF of SHUTTER IN for the actual
shutter open / close operation time.
This terminal is available when the shutter open/close control method is set to I/O at the system settings of
Laser Marker NAVI smart.
X9 SHUTTER ENABLE IN: Shutter open enable input
Control by SHUTTER IN (X8) is available while SHUTTER ENABLE IN is turned ON. To control opening and
closing the shutter by SHUTTER IN (X8) only, short-circuit SHUTTER ENABLE IN (X9) and OUT COM.1 (Y2
or X12).
WARNING
X10 LASER STOP IN
X11 LASER STOP IN
Use these terminals when you want to stop the laser radiation or disable the laser radiation temporarily.
When between LASER STOP IN and OUT COM. 1 is disconnected, the laser radiation will be disabled.
The laser marker operation varies depending on its condition as shown below. For details, refer to "Laser
marker operation when functions for safety measures are input" (P.90).
Terminal connection
LASER STOP IN -
OUT COM.1
• The function relating to safety must be shut off mechanically. Therefore, wire these terminal at no-voltage
contact (dry contact).
• If you need to shut off the laser pumping physically, user INTERLOCK 1 (X16, X17) and INTERLOCK 2 (X18,
X19) instead of these terminals.
X12 OUT COM. 1: Output common 1
The common terminal for each output of the I/O terminal block. X12 and Y2 are the common terminal
connected internally.
For NPN connection, this terminal is connected to the "- (minus)" side of power which is used for control. For
PNP connection, this terminal is connected to the "+ (plus)" side of power which is used for control.
• Do not use SHUTTER IN (X8) and SHUTTER ENABLE IN (X9) as an
emergency stop or the interlock. Turning OFF these terminals during laser
radiation will not close the shutter until the marking completes.
