Sine-Cosine Analog Encoder Connection

Remark:
For Sine-Cosine connection, external 120Ω (0.25W) terminators are required.

3.5.8.7

Digital Hall Connection for Motor + Hall + Incremental Encoder

Remarks:
1. This connection is required when using Hall start method BLDC or PMSM and also for the Trapezoidal
commutation method. The digital halls are not used in this case as a feedback measurement device. The actual
motor control is done with an incremental encoder.
2. The length of the cables must be up to 30m, reducing the exposure to voltage surges in industrial environment.
