■ ■ ■ ■ ■ "DISPLAY RECORDING"
If you have used TESTSETP to define a test run with
different parameters, you can also graphically
display these results after execution (TESTSTART)
with "TESTRUN" → → → → → "DISPLAY RECORDING".
Insofar as this is possible with the parameters you
have selected, i.e. that the result can actually be
displayed with the four graphics.
These four diagrams or seven curves are used as
follows:
(1)
The actual position curve shows the values of
index w1 (see TESTSETP),
(2) the set position curve the values of index w2,
(3) and the current curve the values of index w3.
(4) The actual speed curve shows the difference of
the recorded data to the values of w1; in the
case that position data is being recorded this
means the change in the position in ms =
speed.
(5) The set speed curve shows the difference to the
values of w2; in the case that position data is
being recorded this means the change in the
position in ms = speed.
(6) The actual acceleration curve shows the
difference to the values of the actual speed
(see 4); in the case that position data is being
recorded this means the change in the speed
in ms = acceleration.
(7) The set acceleration curve shows the diffe-
rence to the values of the set speed (see 5); in
the case that position data is being recorded
this means the change in the speed in ms =
acceleration.

■ ■ ■ ■ ■ Evaluating motion figures
Check the maximum position, the maximum velo-
city, the number of "overshoots" and the duration
of the building-up process.
For each graph the most important test run
parameters, the corresponding maximum values
and actual values are displayed:
• velocity in user units/ms,
• acceleration in user units/ms
• the maximum regulation difference which oc-
curred during the process are shown,
• the actual position difference at the target,
• user units in qc,
• data sample interval in ms.
Click on the corresponding input field to view one of
the other graphs, for example for velocity. You can
also view two or even all four graphs at once.
However, then no units are shown on the x-axis.
Repeat
If you click on "REPEAT" then the dialog field for the
test run parameters is opened once again: You can
change the parameters and start a new test run.
"TESTRUN" positioning graph
The positioning graph shows the set positions (dark
or brown curve) and the positions actually
achieved (light or red curve).
"TESTRUN" velocity graph
The yellow (light) curve shows the achieved velocity
path, the brown (dark) curve shows the desired
trapeze-shaped set curve.
