INSTALLATION & USER’S MANUAL
B.2.16.69 Oscilloscope
The DS2110 configuration of WinDrive contains the above
Oscilloscope Panel
. The oscilloscope is an internal
storage oscilloscope with up to four input channels, trigger function, and time base. It can be used to store fast
events or to store information that caused fault conditions. Up to four input channels can be used to sample any of
the controller’s internal parameters. The trigger controls the sampling of the data synchronised to a trigger input,
which can be any of the controller’s internal parameters. It is possible to have a delayed trigger or a pre-trigger.
The slope can be rising, falling, or both.
The Oscilloscope Panel is divided into the following sections:
B.2.16.70.1 Display
Area
This displays the traces, cursors, and trigger position. Traces are shown in their respective colours (i.e. green,
red, pink, or blue). Cursors are shown in blue. The trigger position is shown in orange. At the bottom of the display
area there is a horizontal scroll bar, which allows left and right scrolling when the number of samples taken
exceeds that at which the trace can be fully displayed in the display with the current settings.
B.2.16.70.2 Timebase
Panel
Time per division
: Sets the time represented by each horizontal division in the display area.
Number of samples
: Sets the number of samples taken before the plot is wrapped around to the beginning. When
this occurs, the existing plot is erased. This value can be set to a large number if longer continuous plots are
required.
First Sample On Screen
: This represents the horizontal offset of the display area with respect to the complete
plot. Changing this value has the same effect as moving the timebase scrollbar.
