6. About the Scaling of Feedback Signals

Voltage, current, and position feedback signals from the hardware require scaling into the appropriate physical units (in software) before you can use the data in the control loop

The Drive-On-Chip Design Example for Agilex devices require scaling to convert the feedback samples from alternative ADCs (sigma-delta ADCs) into the same units for use in the FOC algorithm. Also, the design requires scaling to convert current and voltage feedback values to the units expected by motor model module (voltages and currents). The design treats some feedback as "dimensionless" data and scales it into a convenient range (e.g. signed 16-bit integer) for use in the control loop. The design presents data for diagnostic purposes in a GUI. The GUI performs further scaling into physical units for waveform displays.
