Assumptions:

1. The UDC task(s) have been put into run before the vector control algorithm is turned on.

*Communication of command and feedback registers between the UDC and PMI synchronized UDC tasks and PMI

control algorithms are not synchronized. The vector control algorithm runs, on the average, every 1 msec.
