Setting Output Schedules (SCH.#01)
(1) Set the SCHEDULE number by combining pin No.27 to pin No.34 of the EXT. I/O
(2) connector. In this example, pin No.27 of the EXT. I/O (2) connector is put in a
closed circuit for 16 ms or more to set SCH.#01.
⇒
At delivery, the signal acceptance time (time from a signal input till establishment
of schedules) of processing schedules is set to 16 ms. Set the close circuit time
referring to this value. As the signal 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 Chapter 2 "7. Changing the Acceptance Time for Laser Start Signal/
Schedule Signal" on page 121.
When the laser can be output and a valid schedule is selected, pin No.13 of the
EXT. I/O (1) connector is put in a closed circuit and the signal (Ready) is returned
from the laser after 1 seconds maximum.

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.
Pin No.22 (End output) of the EXT. I/O (1) connector is put in a closed circuit for
20 ms and a signal is returned from the laser. Pin No.17 (Monitor normal out-
put) or pin No.20 (Monitor trouble output) of the EXT. I/O (1) connector is put in a
closed circuit for 20 ms and a signal is returned from the laser.
