Display Group Description
Indicates proper operation
Indicates a cautionary or questionable situation
Indicates a severely-limited or non-operation situation
Physical The Physical Group ( Figure 8.6 ) reports measurements for speed, torque, mechanical
power, motor direction, and component temperatures. Any problem measurements are
noted in the Status Group.
Electrical The Electrical Group ( Figure 8.8 ) reports measurements for DC bus voltage and current,
electrical power, and the phase leg currents. Any problem measurements will be noted in
the Status Group.
Critical The Critical Group ( Figure 8.10 ) reports the critical parameters of the position offset and
the phase leg order. If these are incorrect, the situation is dangerous. This danger occurs if
the motor is wired incorrectly to the controller.
Control The Control Group ( Figure 8.7 ) reports the current control mode and control parameters
of the motor system.
Data Logging Data Logging ( Figure 8.4 ) controls the logging capabilities of the software. Data logging
records motor system measurement data to a spreadsheet file in real time at second or
multiple-second rates. The software can log data at these slow rates indefinitely. Details
on logging are located in
Section 8.4 .
Data
Acquisition Data Acquisition ( Figure 8.9 ) controls the data acquisition (DAQ) capabilities of the
Danfoss Power Solutions controller. DAQ records motor system measurement data at
millisecond rates. The data is limited in length, and is recorded into a spreadsheet file
after the acquiring event has occurred. Significant time is required for extraction of the
DAQ data from the controller. Details on DAQ are located in
Section 8.5 .
Status Bar The Status Bar ( Figure 8.11 ) displays the current condition of the RS232 communication
port. Details of the operation of the Status Bar are covered in greater detail in Section
8.2.1 .
8.3.1 Measurement Update Speed
In normal operation, the front panel ( Figure 8.1 ) indicates the present operating conditions of the Danfoss Power
Solutions Motor System. The measurements are updated four times per second at the higher baud rates. Slower
rates, like 38400 and 19200, slow down the measurement rate to approximately twice a second.
Note that the measurement rate is slowed when a DAQ file is being retrieved because removal of the DAQ data
is using almost all of the bandwidth of the RS232 port. One exception is if Data Logging at 4x per second is
occurring. DAQ file retrieval is not maximized so that the requested logging rate is maintained. Front panel
measurements are updated normally in this case.
