6.6. Controlling the Speed and Position Demonstrations

The Drive-On-Chip Design Example speed and position demonstrations show constant or varying speed and position.
  1. Selects the way the speed or position varies during the demonstration in the Waveform drop down.
    The speed or position varies according to the selected waveform.
  2. Specify the Speed (position) to control the nominal speed or position for the respective demonstrations.
    If you select a non-constant waveform, the speed and position vary around this nominal value.
  3. Specify the Period (ms) to control the period of the speed and position variation waveform.
  4. Specify the Waveform amplitude to control the amplitude of the waveform. For example, a speed of 100 rpm with an amplitude of 50 rpm gives a speed varying between 50 and 150 rpm.
  5. Specify the waveform offset (ms): to change the waveform phase (shift in time).
  6. Specify the Position Speed Limit (rpm) to control the maximum speed in position demo mode.
    If you select Speed in Demo on the Waveform Demo tab, the design ignores this value.
  7. Click Update Demo to apply changes to the design.
