5.2 BEAM ON/OFF CONTROL
Overview
When the shutter is open, executing a beam output command causes
the oscillator to radiate the laser beam to the outside.
The beam output command can be issued by either of the following
methods, according to the bit 6 (LHC) of parameter No. 15001.
Using a G code
(1) Using a G code (bit 6 (LHC) of parameter No.15001 is 0)
When the piercing command (G24) or cutting feed command
(G01, G02, G03, G12) is executed, the beam is turned on. When
the command terminates, the beam is turned off. In manual
operation mode, the beam on signal (BEMON) from the PMC
can be used to turn the laser beam on or off.
Using the beam on signal
(2) Using the beam on signal (BEMON) (bit 6 (LHC) of parameter
No.15001 is set to 1)
When bit 6 (LHC) of parameter No.15001 is set to 1, the PMC
can turn the beam on or off in both automatic and manual
operation mode. The beam on signal (BEMON) can be set to 1
when the PMC receives an M code specified in a program. The
M code can turn the beam on or off, instead of the G code. This
method controls the beam through the PMC, causing a delay
relative to beam control with the G code.
Beam lock signal
A beam lock signal (*BEMLC) is supported to ensure safe operation.
This signal can be used to allow specified beam output only when a
key-operated switch is activated.
0: Beam lock status
1: Beam lock released
When the beam lock signal (*BEMLC) is set to 1, the beam lock is
released. When a machining program is executed in this state, the laser
beam is output as specified in the program.
