3. Click in the KPROP box and enter a value
that is approximately one quarter of the value
of KDERIV. If the motor begins to vibrate,
decrease the value of KPROP or increase
the value ofKDERIV until the vibration stops.
Small changes may be all that is necessary.
4. In the Move Type drop down box, check that
the move type is set to S tep.
5. Click inthe Distance boxandenter adistance
for the step move. It is recommended to set
a value that will cause the motor to turn a
short distance, for example one revolution.
Note: The distance depends on the scale set in section 5.3.3.
If you set a scale so that units could be expressed in revolutions (or other unit of
your choice), then those are the units that will be used here. If you did not set a
scale, the amount you enter will be in encoder counts.
6. Click in t he Duration box and enter aduration
for the move, in seconds. This should be a
short duration, for example 0.15 seconds.
7. Click Go.
The NextMove PCI will perform the move and the motor will turn. As the soon as the
move is completed, WorkBench v5 will download captured data from the NextMove PCI.
The data will then be displayed in the Capture window as a graph.
Note: The graphs that you see will not look exactly the same as the graphs shown here!
Remember that each motor has a slightly dif ferent response.
8. Using the check boxes below the graph,
select the traces you require, for example
