Laser Welding by External Input/ Output
Signals (EXTERNAL CONTROL)
1 . Operation Flow
This section explains an operation flow of laser welding by external input/out -
put signals (EXTERNAL CONTROL) .
The following methods for laser welding operations are available: control from the
control panel (PANEL CONTROL), control by external input/output signals from the
PLC (Programmable Logic Controller) connected to the connector (EXTERNAL CON-
TROL), and control by sending a command from the connected personal computer
(RS-485 CONTROL).
At the control by external input/output signals (EXTERNAL CONTROL), output sched-
ules are set by another method (PANEL CONTROL/RS-485 CONTROL) in advance.
After that, such control as schedule selection, laser light output, and emergency stop
is exerted.
* PLC: Programmable Logic Controller This unit exerts sequence control by executing the programmed
contents of control in sequence. This is often called Sequencer (product name of Mitsubishi Electric
Corporation).
