1. The functions of input signals on J2-10, and J3-5,6,7,8,9,10,11,12,13, and 14
are programmable. Default functions are shown.
2. The function of [IN1] on J3-4 is always Drive Enable and is not programmable
3. Pins J3-20, J2-2, and J2-4 all connect to the same +5 Vdc @ 250 mAdc power source.
Total current drawn from both pins cannot exceed 250 mAdc.
4. Multi-mode encoder port (J3-21~26) is shown configured for buffered-output of a digital primary motor encoder.
Page 11 shows connections for analog Hall commutation with digital incremental position feedback.
