[LP-4xx(T)U-C / LP-4xxS9(T)U-C / LP-VxxU-C ]
• Connect A1 [+12V OUT] and A2 [ OUT COM.] , B1 [0V OUT] and B2 [IN COM.] as I/O power supply for marking.
• Connect B12 [EMER.+] and A2 [OUT COM.] to release the emergency stop function.
(Opening between B12 - A2 turns off the laser pumping and marking is disabled.)
• Connect A12 [LASER STOP+] and A2 [OUT COM.] to release the laser stop function.
(Opening between A12 - A2 closes the auto-shutter, and changes the status of the device into invalid for marking.)
• The following terminals are short-circuited by a short bar at factory shipment.
A1 [+12V OUT] ―
B1 [0V OUT] ―
Notice
• Short-circuiting IN COM. and OUT COM. in supplying power might cause the short out and also cause the trouble with
the laser marker.
• [IN COM.] and [OUT COM.] on the I/O terminal block are connected with [IN COM.] and [OUT COM.] on the I/O
connector respectively and internally. Therefore, inverting the power supply wiring for the I/O terminal block and the I/O
connector might cause a short circuit, resulting in the failure of the laser marker.
• Please make sure to check the power wiring before running the laser marker.
• When the laser marker is to be controlled by external power such as PLC, connect - side of the external power to B2 [IN
COM.] and + side to A2 [OUT COM.]. In this case, do not connect externally to A1 [+12V OUT] and B1 [0V OUT] of I/O
terminal block. (If a short bar is installed, remove it.) For details, refer to "2-3-2 Connecting sample with external devices"
(P.44).
Reference
• "Output simulation" and "I/O check monitor" can simulate ON/OFF state on each connector. Please use these functions
in checking the wiring. (Refer to the Operation/Maintenance Manual.)
