⇒
In more than 150 ms after a beam select signal input or in more than the time set
on the CONFIG screen after the setting of welding conditions, close the LASER
START pin.
⇒ At delivery, the laser start acceptance time (time from a signal input till an actual
output of laser light) is set to 16 ms. Set the close circuit time referring to this
value. As the laser start acceptance time, 0.1 ms, 1 ms, 2 ms, 4 ms, 8 ms, or 16
ms can be selected by displaying the CONFIG screen. For details, refer to Chap-
ter 2, "7. Changing the Acceptance Time for Laser Start Signal/Schedule Signal"
on page 109.
⇒
At delivery, the output time for the end signal and the monitor normal/trouble sig-
nal is set to 20 ms. 20 ms, 30 ms, or 40 ms can be selected by displaying the
CONFIG screen.
⇒ Be sure to put the laser start pin in a closed circuit at least for 20 ms.

Setting Output Schedules (SCH .#02)
(1) Set the SCHEDULE number by combining pin No.27 to pin No.34 of the EXT. I/O
(2) connector. In this example, put pin No.27 of the EXT. I/O (2) connector to an
open circuit to turn OFF SCH.#01, and put pin No.28 in a closed circuit to turn on
SCH.#02.

Outputting Laser Light
(1) Put pin No.2 (Laser start) of the EXT. I/O (1) connector in a closed circuit.
Laser light is output from Beam 1.
