7 / 44 page  System Concept DC Motor with Speed and Current Closed Loops, Driven by eTPU on MCF523x, Rev. 0 Freescale Semiconductor 7 3.2 Application Description A standard system concept is chosen for the motor control function (see Figure 4). The system incorporates the following hardware: • Evaluation board M523xEVB • 33395 evaluation motor board • DC motor with optical, Hall-like sensors • Power supply 9V DC, 2.7Amps The eTPU module runs the main control algorithm. The 2-phase PWM output signals for a 2-phase inverter are generated according to feedback signals from optical sensors and the input variable values, provided by the microprocessor CPU. Figure 4. System Concept The system processing is distributed between the CPU and the eTPU, which both run in parallel. The CPU performs the following tasks: • Periodically scans the user interface (ON/OFF switch, up and down buttons, FreeMASTER). Based on the user input, it handles the application state machine and calculates the required speeds, which is passed to the eTPU. • Periodically reads application data from eTPU data RAM in order to monitor application variables. • In the event of an overcurrent fault, the PWM outputs are immediately temporarily disabled by the eTPU hardware. Then, after an interrupt latency, the CPU disables the PWM outputs permanently and displays the fault state. The eTPU performs the following tasks: • Four eTPU channels (PWMF) are used to generate PWM output signals. DC Motor Drive eTPU GPIO enable/disable PWM signals required speed Application State Machine over-current interrupt ON/OFF switch status data monitoring Fault LED CPU Hardware 9 12V DC ÷ ON/OFF DOWN UP FreeMASTER Remote Control RS232 PWM Signals Fault Signal Status LED ADC Trigger AD Converter BLDC motor Hall Sensor Signals Power Stage |
