Setting encoder triggering
Tabs:
2D Image
,
3D Image
Follow the steps below to use encoder triggering. For more information about the
encoder modes, see
.
Open the
Profile triggering
category in the parameter settings section.
1.
Select the
Encoder
radio button.
2.
Set the
Encoder resolution (mm/pulse)
parameter. This value defines the resolution of
one encoder step and can be a value between 0 and 10 000. The value defines
how far in mm the encoder moves per pulse.
3.
Set the
Pulses per profile
parameter. This value defines how many encoder incre‐
ments/decrements are needed to generate a trigger.
4.
Set the
Encoder Mode
to the desired mode.
The
Encoder value
is an informational field and can be reset to 0 by clicking the
Encoder
reset
button.
Encoder type
Ruler3000 supports the encoder type RS-422. It is only possible to change encoder
type using GenICam or GenIStream, see
8.7.3
Image triggering
The camera will acquire 3D images based on an external input signal, for example a
photoelectric switch. If the same photoelectric switch is connected to several cameras
then synchronization at the microsecond level can be achieved. The acquisition of
profiles in the imagecan either be free-running or triggered by an input signal, as
described in the sections
.
Figure 54: Image triggering GUI reference
Select the
Image trigger
checkbox to enable image triggering. If
Image trigger
is not
selected, the camera acquires images continuously.
