Figure 10. Incremental Output Modes

Brushless DC Motor Commutation Mode

The BLDC signals will be used to control the electrical angle information – according to the amount of pole pairs and

the actual mechanical angle position. Refer Figure 11 for an example of n_pole_pairs:=2. For the programming, refer

to Serial Synchronous Interface (SSI) on page 15.
