4 . Programming
This section explains the precautions for programming laser welding by exter-
nal input/output signals (EXTERNAL CONTROL) .
The timing chart of the appendix shows the input signal length and input waiting time
required to correctly operate the laser. Perform actual programming referring to this
timing chart.
In the following, a control flow is explained by taking the case where "Schedule 1" is
first specified and then "Schedule 2" is specified to perform a single laser light output
from Safety shutter 1, as an example.
1
Switching the Control Method
(1) Put pin No.25 (control switching) of the EXT. I/O (1) connector in a closed circuit.
Pin No.23 of the EXT. I/O (1) connector is put in a closed circuit and the signal
(external input acceptable) is returned from the laser.
⇒
Press the "STATUS" button on the control panel to display the STATUS screen.
Then, you can confirm that "EXTERNAL CONTROL" is selected as the control
method.
2
Turning ON the LD
(1) Put pin No.4 of the EXT. I/O (1) connector in a closed circuit to turn ON the LD.
Pin No.13 of the EXT. I/O (1) connector is put in a closed circuit after 5 seconds
maximum and the signal (LD ON) is returned from the laser.
⇒
The signal is not output until the temperature of fiber laser module becomes
10°C. (1 hour max.)
3
Selecting a Beam (Setting the Safety Shutter)
(1) Put the pin corresponding to the beam in a closed circuit. In this example, pin
No.16 of the EXT. I/O (2) connector is put in a closed circuit to select Beam 1.
The safety shutter is opened and the corresponding SHUTTER lamp comes on.
