MOTOR CONTROL CHARACTERISTICS (Cont’d)
Figure 154. Example 5: Waveforms for sensor HST update timing diagram for a newly selected
phase input
Sampling of sensor input is done at f
for input selection, you have to wait:
1) 1/f
2) 100ns corresponding to the comparator & multiplexer propagation delay (d)
3) 1/f
4) 1/fmtc to resynchronize the data and set the HST bit
