Timing Chart
An example of timing chart for the case where the LD power supply is turned
on and laser light is output up to a monitor output is shown below. In each tim-
ing chart, the equipment operation is represented on the axis of ordinates and
the lapse of time is represented on the axis of abscissas to show the change
status based on changes with the lapse of time at each operation and the time
required for a certain operation.
The following 5 types of timing chart are mentioned for your reference.
Single
Operation by laser controller (PANEL CONTROL)
Operation by external input signals (EXTERNAL CONTROL)
2-powersharing
Operation by external input signals (EXTERNAL CONTROL)
Repeated operation (EXTERNAL CONTROL)
Repeated operation (50 pps or more) (EXTERNAL CONTROL)
⇒
The control method is switched by putting pin No.25 of the EXT. I/O (1) connector
in an open circuit or a closed circuit.
For PANEL CONTROL in which control is exerted by laser controller, put this
pin in an open circuit. For EXTERNAL CONTROL in which control is exerted by
external input/output signals, put this pin in a closed circuit.
⇒
For the laser controller, laser light is output by pressing the LASER START/STOP
button and stopped by pressing this button once again.
For external input/output signals, laser light is output by putting pin No.3 of the
EXT. I/O (1) connector in a closed circuit and stopped by putting this pin in an
open circuit.
