8.5 Data Acquisition
Danfoss Power Solutions’ data acquisition (DAQ) feature is a powerful diagnostic tool for your system design.
The Danfoss Power Solutions Motor System measures the torque, voltage, current, and speed of your system.
DAQ makes that information available to you with fast and accurately timed sampling rates. DAQ records motor
system measurement data at sub-second rates. The data is limited in length, and is recorded into a spreadsheet
file after the triggering event has occurred.
Significant time is required to extract the DAQ data from the Danfoss Power Solutions controller. The amount of
time is dependent on the baud rate and whether Data Logging is also occurring. If your connection speed is
115200 baud and you are not logging, then a download takes approximately 50 seconds. If you are Data
Logging at a four times per second rate, then an additional 20 seconds is added to the extraction time. Files take
several minutes to extract when running at a baud rate of 19200.
The measurement data taken and stored in a data acquisition file is identical to the data stored in a data-logging
file; it is simply taken at a faster rate and has a controlled length. See
Table 8.8 for details of the measurements in
a data acquisition file. In addition, a diagnostic Danfoss Power Solutions file is generated, useful to the Danfoss
Power Solutions factory when advanced diagnostics are required.
DAQ Configuration is accessed via the menu choice
Actions > Daq Configuration
. Choices found in the pop-up
menu accessed from this point are described in Table 8.9 .
