and INTERLOCK COM. (No.1) are short-circuited at the delivery state.
„ Signals and details of interlock connector
• INTERLOCK IN on the interlock connector are connected to the operating coil of the internal relay in the controller.
Connect INTERLOCK IN and INTERLOCK COM. with the non-voltage contact (dry contact) such as a relay or a switch.
Do not connect with the voltage contact such as a transistor.
No. Name and description
1 INTERLOCK 1 COM. (on Interlock 1 connector)
INTERLOCK 2 COM. (on Interlock 2 connector)
Common terminal for the interlock connector.
Connect each INTERLOCK IN (No.3) and INTERLOCK COM. (No.1) with the non-voltage contact (relay output
terminal etc.) of the safety devices such as door, switch or safety PLC.
• INTERLOCK 1 COM. and INTERLOCK 2 COM. are not connected to the common terminals (IN COM., OUT
COM.) of I/O terminal and I/O connector.
2 FEEDBACK 1 OUT (on Interlock 1 connector)
FEEDBACK 2 OUT (on Interlock 2 connector)
When both of INTERLOCK 1 & 2 IN are not connected with INTERLOCK 1 & 2 COM. respectively, the connection
between FEEDBACK 1 OUT - FEEDBACK 2 OUT becomes "CLOSE" status.
By using these terminals, the contact failure of Interlock internal circuit can be detected.
Since FEEDBACK 1 OUT and FEEDBACK 2 OUT are connected internally, the contact status of INTERLOCK 1
IN and INTERLOCK 2 IN cannot be monitored individually.
The connection between FEEDBACK 1 OUT and FEEDBACK 2 OUT is switched open and closed with a delay of
approx. 20 ms with reference to the status of INTERLOCK 1 IN and INTERLOCK 2 IN as shown below.
INTERLOCK 1 IN - INTERLOCK 1 COM.
INTERLOCK 2 IN - INTERLOCK 2 COM.
FEEDBACK 1 OUT - FEEDBACK 2 OUT
3 INTERLOCK 1 IN (on Interlock 1 connector)
INTERLOCK 2 IN (on Interlock 2 connector)
To enable the laser radiation, connect INTERLOCK IN (No. 3) and INTERLOCK COM. (No. 1) with the non-
voltage contact (dry contact) such as a relay or a switch.
When the connection between INTERLOCK IN (No. 3) and INTERLOCK COM. (No. 1) is opened, the laser
pumping is turned OFF and the shutter is closed.
