Browse button
Enter the directory where DAQ files should be written. Browse brings up a File Open
dialog box. Use it to point to the directory you want to use.
Include in Name
Text that you want included into the DAQ filename. It will include the date, this text,
and an incrementing number.

Re-enable trigger
Re-enables the trigger immediately after a DAQ data file has been completely
downloaded.
NOTICE You must ensure that the triggers selected are not still active when the re-
enable occurs. For example, a trigger of “Position signal is bad” if re-enabled
immediately will also immediately cause another file to be gathered. This will
continue until you manually cancel or until your disk is full.

cause a trigger.

DAQ Set Up Example
The DAQ feature of the Danfoss Power Solutions Motor Diagnostic Software is very useful when you need to
diagnose a dynamic problem in your system. Because the Danfoss Power Solutions motor is connected to most
of your system’s components, its measurements can help you find problems. For example, if your soft-start
functionality is connecting and then disconnecting a short time later, Danfoss Power Solutions Motor’s DAQ can
be used to trigger and collect fast data around this event so that you can see what your high voltage bus is
