The Vector Engine provides the following features:
Vdc
15.1.1 Features
1) Executes basic tasks for vector control (coordinate conversion, phase conversion and SIN/COS
2) Enables interface (output control, trigger generation, input processing) with the motor control circuit
3) Calculates current, voltage and rotation speed by using normalized values with respect to their
4) Implements PI control in current control.
5) Implements phase interpolation (integration of rotation speed). .

Current control
Uses fixed-point format data.
Converts computation results from fixed-point format to data format usable in the PMD.
Generates timing data for interactive operation with the PMD and ADC.
Converts AD conversion results into fixed-point format.
