Analog control and ramp function
It is not possible to use ramping times together with
the analog control.
7.5 ROBOT mode
External control in ROBOT mode
In ROBOT mode, the laser emission can be controlled
via the External control function. In the operating
mode TEST, this is activated via the button External
control OFF
in the LaserNet tab Control. After
switching to the ROBOT mode, the function remains
active.
1. Follow the steps described in the section Switching on/off [}59]
to switch on the laser in ROBOT mode.
2. Establish a connection to the laser, if this has not already been
done (Establishing a connection to the laser [}74]).
3. Start the LaserNet software (Starting LaserNet [}76]).
The LaserNet software is used for monitoring the laser operation. All
LaserNet buttons, incl. the buttons Reset
and E-Stop are disabled. This
can also be deactivated, if necessary. Detailed information about the
LaserNet software can be found in the section (LaserNet software
[}70]).
Checking the
beam path
After maintenance work and a prolonged shutdown of the laser, the
beam path must be checked with the help of the guide laser.
The guide laser switches on. The corresponding signal is sent back from the laser
to the robot as confirmation.
4. Check whether the guide laser is visible at the outlet of the
process optics and has no irregularities. You can do this, for exam-
ple, by holding a white sheet of paper in front of the process op-
tics and looking at the laser spot.
5. Contact the responsible IPG service department if the laser spot at
the outlet of the process optics is invisible or exhibits irregulari-
ties such as dark spots. Do not turn on the laser emission if this is
case.
