General Tab

Under Data Source:

  • In the DSP mode drop-down menu select DSP calculation mode to use (Software Fixed Point; DSP Builder for Intel FPGAs Fixed point; DSP Builder for Intel FPGAs Floating Point or Software Floating Point)
  • Under the ADC Type drop-down menu, select the ADC to use for feedback samples (depending on the power board you use)
  • Click Show Raw Samples to show raw or scaled samples.
Figure 13. General Tab

On the Demo selection: drop-down menu select the control algorithm, type of commutation, and update rate to use in the demonstration. The available selections depend on which motor control hardware you use.

The Status: field reports the status of the demonstration. The Runtime: field updates from the application software.

The Run time measurement dials display the processing time of the FOC control loop and the overall Interrupt Service Routine (ISR) processing time, including handling debug trace data. in the currently selected DSP mode.

Waveform Demo Tab

In the Demo drop-down menu select speed, position, or other demonstration.

In the Waveform drop-down menu select the dynamic behavior of the speed or position demo (constant or varying with sine, square, triangle, sawtooth waveform).

Set the nominal speed or position, waveform period, amplitude and offset and click Update Demo.

Note: Large step changes in commands (e.g. using square or triangle wave speed demo) may result in unstable behavior, especially when using sensorless control.

Demonstration Selection

The Demo selection: drop-down on the General tab selects the demo to run:

  • Reset
  • Open loop sinusoidal 16 kHz Volts/Hz
  • Open loop sinusoidal 32 kHz Volts/Hz
  • FOC sensor 16 kHz single axis
  • FOC sensor 32 kHz dual axis
  • FOC sensorless 16 kHz dual axis
  • FOC sensorless 32 kHz dual axis
  • Trapeziodal Hall sensor 32 kHz dual axis

Battery Monitor

The Battery Monitor tab shows the battery initial parameters, battery monitor control, and status of battery, including SOC and parameter values.
