*10/31/03 2.00 Released Motor runs fine, still some loose ends
*
*12/19/03 2.01 Cleaned up structure, created UserParms.h for all user defines.
*
*02/12/043.00-Removed unnecessary files from project.
*
-Changed iRPM to int to correct floating point calc problems.
*
-CalcVel() and velocity control loop only execute after number of loop periods
*
specified by iIrpPerCalc.
*
-Added iDispLoopCount variable to schedule execution of display and button routines
*
-trig.s file changed to use program space for storage of sine data.
*
-Added DiagnosticsOutput() function that uses output compare channels to
*
output control variable information.
*
-Added TORQUE_MODE definition to bypass velocity control loop.
*
-Turned off SATDW bit in curmodel.s file. The automatic saturation feature prevents
*
slip angle calculation from wrapping properly.

Code Description
*
*
This file demonstrates Vector Control of a 3 phase ACIM using the dsPIC30F.
*
SVM is used as the modulation strategy.
