Signal Name
You can customize the information presented by the Scope tool by choosing the drop-down box in each channel. The set of
available signal depends on the drive model. Refer to the User’s Manual appropriate for your drive model to see 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 division for every change of 100 RPM in the signal level. Thus, a
500-RPM signal would deflect the signal by five 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 the same side of the central reference line.
Time Base
Time base sets the number of cycles displayed per division. Higher frequencies have a shorter time base than lower frequen-
cies. 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 trailing or falling 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 again.
