Opening the Resonator Shutter
(1) Close pin No.24 of the EXT.I/O (1) connector.
The resonator shutter is opened and the flashlamp comes on. Then, a laser light
output is enabled.
5
Setting Output Schedules (SCH.#01)
(1) Set the SCHEDULE number by combining pin No.29 to pin No.33 of the EXT.I/O
(1) connector. In this example, pin No.29 of the EXT.I/O (1) connector is put in a
closed circuit for 16 ms or more to set SCH.#01.
⇒
Refer to "SCHEDULE Number Selection" on page 133.
⇒
At delivery, the signal acceptance time (time from a signal input till establishment
of schedules) of welding schedules is set to 16 ms. Set the close circuit time
referring to this value. As the signal acceptance time, 0.1 ms, 1.0 ms, 4.0 ms,
8.0 ms, or 16.0 ms can be selected by displaying the MEMORY SWITCH screen
from the INITIALIZE screen. For details, refer to Chapter 2, "3. Changing the
Acceptance Time for Laser Start Signal/Schedule Signal" on page 113.

Outputting Laser Light
(1) Put pin No.20 (Laser Start) of the EXT.I/O (1) connector in a closed circuit.
Laser light is output simultaneously from Beam 1 and Beam 2.
Pin No.4 (End output) of the EXT.I/O (1) connector is put in a closed circuit for 40
ms and a signal is returned from the laser. Pin No.5 (Monitor normal output) or
pin No.6 (Monitor trouble output) of the EXT.I/O (1) connector is put in a closed
circuit for 40 ms and a signal is returned from the laser.
