Trace

On the Trace section select:

  • The waveform tracing by specifying a trigger.
  • Axis to trace.
  • Trace depth.
  • A filename to store the trace data.

Click Update Trigger after making any changes. Click Start Trace to start tracing. Click the Waveform tab for trace display. When saving trace data to a file, the design overwrites the file with each trace. It does not append new traces to an existing file.

Current Control Parameters

Expand the Parameter tap in the bottom-left. On the Current Control, enter the proportional gain (Kp) and integral gain (Ki) coefficients for the current control loop. These quantities are preset to the correct values for the motor type configured in the application software. Click Update Parameters after making a change.

Speed Control Parameters

Expand the Parameter tap in the bottom-left. On the Speed Control area, enter the Speed Kp and Speed Ki coefficients for the speed control loop. These quantities are preset to the correct values for the motor type configured in the application software. Click Update Parameters after making a change.
