System Concept

System Outline

The system is designed to drive a 3-phase permanent magnet synchronous motor (PMSM). The application meets the following performance specification:
Application Description

A standard system concept is chosen for the drive. The system incorporates the following hardware: The eTPU module runs the main control algorithm, independently on the CPU. PWM output signals for a 3-phase inverter are generated according to the input variable values, provided by the microcontroller CPU.
The microcontroller processing is allocated between the CPU and the eTPU, which run in parallel.

The CPU performs the following tasks: The eTPU performs the following tasks:
