The status indicators Laser ON and Laser ready are deactivated.
7.4.2 Working with the laser program
1. Make certain that the laser power supply is switched on.
2. Select the program number (4) of the laser program you would
like to work with in the Control tab [} 97]. Information on pro-
gram creation can be found in the section LaserNet program edi-
tor [}106].
3. Click on the button Start program
(4).
During execution of the program, the button Start program
changes to
STOP
. In addition, the status message Program active is activated. After
the end of the laser program, the status End of program is activated. The
status message Program active is deactivated.
An interruption during the execution of the laser program is indicated

7.4.3 External control
The external control can be configured as another condition for switch-
ing on the laser radiation in the laser.
External control in ROBOT mode
The function of external control is activated in the
TEST mode via the button External control OFF
on
the Control tab in LaserNet. The function remains
active even after switching to the ROBOT mode.
For switching the laser emission on and off via the external control, the
signal Emission ON at the safety interface is used.
HIGH signal (+4 … 30 VDC) – Emission ON
LOW signal (-3 … + 2 VDC) – Emission OFF
This signal can be used for modulation of the laser radiation. This re-
quires a signal generator that outputs a square wave. The laser radia-
tion can be modulated with a frequency up to a maximum of 5,000 Hz.
