Laser Welding by External Input/ Output
Signals (EXTERNAL CONTROL)
1. Operation Flow
This section explains an operation flow of laser welding by external input/
output signals (EXTERNAL CONTROL).
The following methods for laser welding operations are available: control from the
laser controller (PANEL CONTROL), control by external input/output signals from
the PLC (Programmable Logic Controller) connected to the connector (EXTERNAL
CONTROL), 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
schedules 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).
