Sensor Calibration

Compute offsets for position, current, and voltage

Compute the offsets for Hall sensor, quadrature encoder sensor, and ADC to accurately calculate the position and current feedback values.

Topics

Hall Offset Calibration for PMSM Motor

This example calculates the offset between the rotor direct axis (d-axis) and position detected by the Hall sensor.

Quadrature Encoder Offset Calibration for PMSM Motor

This example calculates the offset between the d-axis of the rotor and encoder index pulse position as detected by the quadrature encoder sensor.

Run 3-Phase AC Motors in Open-Loop Control and Calibrate ADC Offset

This example uses open-loop control (also known as scalar control or Volts/Hz control) to run a motor.
