Check the reference pulse (RI)
With the diagnostic unit, the reference pulse can be checked exactly. To perform this test, select the "RI"
button in "DATA-Source".
It can be chosen between the absolute and relative representation. The time representation (here on the X-
axis) can also be adjusted individually. In the relative representation, only the time range before and after
crossing the reference pulse is displayed. This is useful to look idividually at the reference pulses. In the case
of absolute representation, the display runs constantly and the time interval between two reference pulses
can be checked.
To use the zoom function in the time representation,
press "Pause", this will freeze the measurement.
Then you can select a starting point with the left
mouse button (in the example picture on the top
left). From this point, press the left mouse button
and drag it over the desired area. (In the example
picture to the bottom right). This function is useful
for the SIN/COS signals and for the reference pulse.

-Interface pro-
viding output signals which can be highly inter-
polated.
The sine shaped incremental signals A and B
are electrically 90° phase shifted and have a
signal amplitude of 1Vpp. The showed se-
quence of the outputet signals - B after A - is
valid for the positive direction of movement.
The reference mark signal R has a clear as-
signment to the incremental signals as shown
in the diagram.
For referencing the encoder, only the
reference pulse signal from scanning
head # 1used.
The zoom function is reset with a right-click.
