Tom,

1. Make sure you do have EnableFlag=1, in the watch window, without which ISR will not be executing
2. Make sure your SpeedRef is a non zero value
3. enter svgen_dq1.Ta and see if the value is changing ? you will have to specify the Q format to be Q24

Please report back once you have investigated 1,2 and 3.

regards
Manish
