Tips:
•
No waveform is visible when no events are detected.
•
If excessive shaft voltage is measured, check that the
voltage discharges can be reduced by adapting the
cabling, grounding, drive parameters, or lubricant. If this
is not possible or does not help, use the shaft grounding
devices or the isolated shaft.
•
If a bearing runs hot or is noisy and high shaft voltages
are measured, bearing flash-over currents can be the
primary source of excessive bearing wear.
•
Check other sources of bearing wear, such as, coupling
misalignment or looseness.

The test tool automatically stores the 100 most recent
screens:
1. Push
or
to freeze memory contents.
2. Use the functions in the
REPLAY
menu to step back
through the stored screens to find the screen of interest.
You can use this feature to see previous measurements,
such as the last shaft voltage discharge waveforms.
To save a replay screen to a report:

Report
The MDA-500 Series simplifies the process of gathering
data and writing test reports with a built-in report generator.
At each test point or measurement there is the option to
create, update, or modify a report:
1. Push
SAVE TO REPORT
to save the screen
as a .png file.
2. Enter a name for the drive that is measured.
The test tool uses the drive name as the name of a
directory and automatically creates names for the .png
files based on the selected measurement.
3. When all measurements on a drive are done, push
CLOSE REPORT
in the Main Motor Drive
menu.
4. The next time you push
SAVE TO REPORT
,
enter a new name for the report.
5. After a report is closed, push
COPY REPORT
TO USB to save a report to a USB drive.
The USB drive included with the test tool has 2 GB of
memory and is the maximum memory size supported
by the test tool.
6. Push
DELETE REPORTS
to remove saved
reports and free up the internal memory.
