Execute
execute 3-phase V/Hz Motor Control application, choose Program/Debug command CodeWarrior IDE, followed command. execute 3-phase V/Hz Motor Control application's internal Flash version, choose Program/Debug command CodeWarrior IDE. When loading finished, jumper disable JTAG port enable boot from internal Flash, then push RESET button. more help with these commands, refer CodeWarrior tutorial documentation following file located CodeWarrior installation directory <.>\CodeWarrior jumper settings, 56F8346 Evaluation Module Hardware User's Manual. Once application running, move RUN/STOP switch position required speed with UP/DOWN push buttons. Pressing UP/DOWN buttons should incrementally increase motor speed until reaches maximum speed. successful, 3-phase Induction motor will spinning. Note: RUN/STOP switch position when application starts, toggle RUN/STOP switch between STOP positions enable motor spinning. This protection feature that prevents motor from starting when application executed from CodeWarrior. should also lighted green LED, which indicates that application running. application stops, green blinks frequency 2Hz.
