doing during this time. In this example, you would set a trigger on the event of the voltage bus value reaching
250 V. You want several seconds of data, taken mostly after the triggering event occurs. To use the DAQ system
to capture this event, perform the following steps:
1.
Select the “Set up” on the front panel to bring up the “DAQ Set Up” dialog box.
2.
Using the
Browse
button, select a directory where DAQ files should be placed.
3.
Enter “softStart” in the “Include in Name” box.
4.
Click on the trigger
when
: “Bus voltage reaches trigger level.”
5.
Click the
Trig Levels
button to enter the “Trigger Thresholds” dialog box.
6.
Enter 250 in the Bus Voltage box, and select
OK
to close the Trigger Thresholds dialog box.
7.
Select the last radio button in the “Data Spacing and Length” area that is labeled “3.625 secs of
data, 6.240 msecs rate.”
8.
Drag the “Trigger Point within Data Buffer” slider bar to the left until it is close to the left side (it
cannot get closer than 5% of the buffer).
9.
Select
OK
on the DAQ Set Up dialog box.
You are now ready to begin the soft-start procedure. Once the bus voltage reaches 250 V, Danfoss Power
Solutions’ DAQ system triggers and captures the event. The data is extracted automatically by the Danfoss
Power Solutions Motor Diagnostic Software and written to a file placed in the directory you selected.
During the extraction, the status message area (at the bottom of the front panel) shows the progress. Data
extraction takes approximately one minute when running at 115200 baud rate. Once the file is finished, the
Show File
button becomes available. Clicking on it starts your spreadsheet program, opening the file last written
by DAQ.
If the data points are too far apart when you look at the data, re-open the DAQ Set Up dialog box and change
the “Data Spacing and Length” selection to a faster rate. (It will record over less time.) Select
OK
to close the
dialog box and re-initiate the event in your system. Again, when the voltage reaches 250 V, data is captured, and
a new file is written in the same directory with the same name, except for an incrementing number. It does not
overwrite old data.
We recommend saving the useful DAQ configurations you have set up to a QDC file. With a QDC file, you can
return the Danfoss Power Solutions Motor system to particular settings at any future time.

Event Log
Another helpful diagnostic tool in Danfoss Power Solutions Motor Systems is the Motor Event Log. The Danfoss
Power Solutions controller tracks and stores all the system error events that occur and when they occurred into
persistent memory. The diagnostic software provides access to this information through the “Event Log” dialog
box illustrated in
, which is available through the menu choice
Actions > Show Event Log
, or its
toolbar button.
The Event Log shows when error events occurred during operating time. It also logs the wake up condition of
the controller.
lists the possible logging entries.
The dialog box consists of two lists: the event statistics and the event details. The statistics show which events
have happened and how many times they have happened. The details show the order of the events from oldest
to newest, and when they happened relative to controller turn-on. A line item in the statistics list can be used to
find one entry in the details list by selecting it and pressing the
Find
button.
