1.2.4 Sensors inputs
Several types of sensors can be used :
• Differential Quadrature Encoder Interface (QEI) (A+, A-, B+, B-, I+, I-)
• Single Ended Quadrature Encoder Interface (QEI) (A+, B+, I+)
• SSI absolute encoder (Tx, Rx)
• Digital Hall sensors (H1,H2,H3)
There is 2 different connectors for sensors. A main 8 positions connector with QEI differential or single ended with 2 or
3 signals it can also use an SSI encoder using RS422 or RS485 communication up to 16 Mbit/s.
