Parameters
Signal Name
The user can customize the information presented on the Scope tool by choosing the drop-down box in each
channel. The set of available signals depends on the drive mode. Refer to the Oscilloscope Parameters table
for the list of the signals.
Scale
Scale sets the sensitivity of the display. Each division is considered one unit of the selected scale. A scale
of 100 RPM/div, for example, means that the signal will rise (or descend) by one vertical division for every
change of 100 RPM in the signal level. Thus, a 500-RPM signal would deflect the signal by five vertical
divisions from the central reference line.
Offset
Offset sets the vertical distance from the central base line to the signal trace. This is useful if you want to
compare two signals. For example, if you wish to compare the actual vs. commanded motor velocity, you
would enter an offset that would move the two signals to alternate sides of the central reference line.
Time Base
Time base sets the number of milliseconds displayed per horizontal division. Higher frequencies have a
shorter time base than lower frequencies. If you wanted to display one cycle of a particular signal, your time
base setting would therefore be lower for high-frequency signals than for low-frequency signals.
Trigger/Trigger Level
Trigger level specifies the signal level after which the scope starts acquiring data. You can also specify
which channel will be a source for the trigger. The oscilloscope display will continue to run while the signal
level crosses the specified level (above if the trigger is set for rising or leading edge, or below if the trigger
is set for falling or trailing edge).
Single
Also called one-shot trigger. If Single Sweep is selected, data acquisition will be stopped after the scope
buffer is filled and data displayed on the screen (frozen data). To repeat data acquisition, you will need to
click the
Single button again.
Run / Stop
Select [Run] for a continuous trigger. Select [Stop] to disable the trigger.
Set on Top
Select this button to display the oscilloscope window on top of all other windows.
5.10.2 Parameter & I/O View
The [Parameter & IO View] tool permits the user to access the list of variables. Click on the [Parameter &
IO View] button to open the diagnostic tool in a separate window. Click on the box adjacent to [Set on Top]
to keep this window on top. Also known as the Debug Tool, the Parameter and I/O View permits the user to
view the values of the drive’s variables plus the I/O status.
To add a variable to the View List, click on [Add] then browse to [Variable Name] in the pop-up window,
then click on the left arrow button. To remove a variable from this View List, click on the variable name in
the View list and then click on the right arrow button. To save the variable list, click [Save]. To load the
variable list, click [Load].
