7.4.4 Analog control
With the Analog control function, you can define the preselected power
via the analog interface. The function is also available in ROBOT mode
(see interface description in the supplied technical data).
To use the Analog control function, a direct voltage signal of 0…10 VDC
must be present at the analog interface (see supplied technical data).
This signal can be used for modulation of the laser power. This requires
a signal generator.
To define the power preselection via the analog interface, do as follows:
1. Establish a connection to LaserNet, if this has not already been
done (TEST mode [}62]).
2. Open the Control tab [}97].
Activating the
analog control
3. Press the button Analog control OFF
(10).
The button then changes its status to ON. The analog control is activated.
4. Click on the button Laser OFF
(5).
The button then changes its status to ON. The laser power supply switches on.
5. Select the laser output power via the analog interface (see sup-
plied technical data).
An input voltage of 0 VDC corresponds to a laser power of 0 W, 10 VDC
corresponds to the nominal output power. The laser power can be set
via the signal Analog control. The exact setting range of the laser power
can be found in the supplied technical data.
6. Click on the button Laser emission OFF
(6).
The button then changes its status to ON. The laser radiation is enabled. The laser
emits the preselected laser power. You can change the power at any time via the
connected input voltage of the analog interface.
7. Click on the button Laser emission ON
(6).
The button then changes its status to OFF. The laser emission stops.
8. Click on the button Laser ON
(5).
The button then changes its status to OFF. The laser power supply switches off.
Combining analog and external control
Usually, the analog control (preselection of the laser
power) is combined during laser operation with the
external control (enabling or modulation of the laser
radiation). In this case, you need another external di-
rect current module and you must activate the func-
tion External control [}64] in LaserNet.
