„ Input signal operation on the I/O terminal block
• The ON/OFF listed in this section refers to the ON/OFF operations. It does not refer to the voltage level (High/Low).
No. Name and description
X1 24V OUT: Internal power supply + 24V DC (max. output current 300mA)
Power for I/O control when the laser welding machine is not connected to the external control device.
X1 and Y3 are the common terminal connected internally.
• Make sure to use X3 or Y1 for the 0V of the internal power 24V (X1 and Y3). Do not mix the connecting pattern for
using external and internal power supply.
• Do not connect anything to this when using the external power supply.
• When using the internal power supply (X1, X3, Y1, Y3), the total current of the power supply for the external device
and the consumption current for the I/O control should be less than 300mA.
X2 IN COM.: Input common
The common terminal for each input of the I/O terminal and I/O connector. IN COM. (X2) and IN COM. (No.1)
of I/O connector are the common terminal connected internally.
In case of NPN connection, this terminal is connected to the "+ (plus)" side of power which is used for control.
In case of PNP connection, this terminal is connected to the "- (minus)" side of power which is used for control.
For details, refer to "4-3-2 Connecting common terminals" (P.100).
• Do not invert the power wiring of I/O terminal and I/O connector. It may cause a failure.
• When this terminal is connected to the power supply, it is not necessary to supply the power to the other IN COM. on
I/O connector.
X3 0V OUT: Internal power supply 0V
Power for I/O control when the laser welding machine is not connected to the external control device.
Y1 and X3 are the common terminal connected internally.
• Make sure to use X1 or Y3 for the internal power 0V (X3 and Y1). Do not mix the connecting pattern for using external
and internal power supply.
• Do not connect anything to this when using the external power supply.
X4 RESERVE: System reservation
Do not connect externally.
X5 REMOTE IN: Remote mode input
While this input is turned on, the laser welding machine operates in the remote mode which can be controlled
externally by I/O and serial communication commands.
To transit to the remote mode using this terminal, turn ON the DIP switch No. 5 in advance.
Refer to "3-5-3 Remote mode settings" (P.81).
X6 TRIGGER IN: Lasing trigger input
The signal to start laser radiation. Starts lasing by edge of input ON. This signal can be accepted while
READY OUT (Y6) is turned ON.
When the trigger mode is set to "single trigger", one lasing operation is executed by the edge of turning on of
TRIGGER IN.
When the trigger mode is set to "continuous trigger", lasing operation is repeated while TRIGGER IN is on.
• When the trigger delay time is set in the selected file, lasing operation starts after the delay time.
• Trigger mode is specified in each file by settings in the file option screen of the laser welding machine.
