For encoder signal reception, an analog differential line receiver with an hysteresis comparator is used. The high signals (ENC_A+, ENC_B+ and ENC_Z+) are
pulled up to +5 V, and the low signals (ENC_A-, ENC_B- and ENC_Z-) are biased to 2.5 V. This arrangement let user to connect either open collector and totem
pole single-ended output encoders, or differential output encoders.
The encoder interface accepts an RS-422 differential quadrature line driver signal in the range of 0 V to 5 V up to 10 MHz. When single ended encoder is
connected, only high signals (ENC_A+, ENC_B+ and ENC_Z+) must be used.
Next figures illustrate how to connect a differential and a single ended encoder to the Jupiter Servo Drive. Refer to
