Hall Sensor vs Motor Output sequencing
The controller requires the Hall sensors inside the motor to be 120 degrees apart. The controller’s 3-phase
bridge will activate each of the motor winding according to the sequence shown in the figure below.

FIGURE 6. Hall Sensors Sequence
Connection to SSI Absolute Encoder
In Sinusoidal Mode, the controller can use motors equipped with absolute angle sensors with SSI interface.
When enabled, the SSI signals are found on the 6-pin Molex connectors that is otherwise used for the Hall
Sensors. The controller issues a differential clock signal and expects a up to 16-bit differential data signal from
the encoder. When two motors are used, these signals must be connected to both sensors. Serial data from
each sensor is captured on separate input pins.

Connection to Analog Sin/Cos Absolute Encoder
The SBL23xx has 4 high-speed analog inputs that can be used to capture absolute angle position from
resolvers or magnetic sensors with sin/cos voltage outputs. The signal must be 0-5V max with the 0 at 2.500V.
The table below shows the signals assignment on the 25-pin connector.
Table 3, on next page, shows the signals assignment on the 25-pin connector.
