Trigger
Description
Turbo Mode occurs
A trigger occurs when the motor enters Turbo Mode. Turbo Mode is Danfoss
Power Solutions’ proprietary control algorithm that produces outstanding power
and efficiency at high speeds.
Limp home mode
occurring
A trigger occurs when the inverter detects a condition that required it to enter
Limp Home Mode
Power switches off
permanently
A trigger occurs when the inverter detects a condition that requires it to shut
down the IGBT Switches
In addition to these triggering capabilities, DAQ allows you to specify the percentage of the data that is recorded
on either side of the trigger event. By moving the slider shown in
towards the left, the amount of
data recorded before the trigger event is decreased, and the amount of data recorded after the trigger event is
increased. The opposite can be achieved by moving the slider to the right. There are also six different sampling
rates, from 80 microseconds to 6 milliseconds, allowing for a wide range of time windows.
Since the software monitors DAQ triggers and automatically uploads the DAQ event capture buffer on trigger
completion, the CSV file is automatically generated. You can specify the directory it is placed in, and you can
specify a name that will be included in the filename. By default, the name is “trigger” because this is the default
trigger source. For example, a couple of inverter fault-triggered DAQ files, occurring in a row, on June 21st, 2013,
would be named:
20150318_trigger00.csv
20150318_trigger01.csv
Note that the DAQ feature also automatically saves a file with the extension “
.uqm
”. This file contains additional
log data that Danfoss Power Solutions can use in diagnosing issues. If you are experiencing problems, we usually
request that you e-mail both the “
.csv
” log file and the “
.uqm
” file to Danfoss Power Solutions.

DAQ Set Up
You must configure DAQ before using it. The configuration parameters of trigger events, fill line, sampling
speed, file directory, and ‘name to be included’ in filename must all be set. The DAQ Set Up dialog box provides
this functionality.
shows this dialog box, and
lists the set up components with
descriptions.
Note that the DAQ trigger settings and data spacing settings do not persist between resets. In other words, if
you power cycle the inverter, you will have to enter your DAQ settings again. Fortunately, the Save/Load to
Config File (“
.QDC
” file) feature makes it easy to restore settings. Please refer to the example in
Section 8.5.1
for
details.
