3.1.1 X1/STEP and X2/DIR High Speed Digital Inputs
X1/STEP and X2/DIR are high-speed digital inputs operation 5-24V optical isolated single-ended
or differential signal. The maximum input frequency is 2MHz.
 In Pulse and Direction mode, X1/STEP is pulse input,and X2/DIR is direction signal input.
 In CW/CCW mode, X1/STEP is CW pulse input,and X2/DIR is CCW pulse input.
 In A/B quadrature signal mode (Encoder follows), X1/STEP is signal A input, X2/DIR is signal B
input.
 In velocity mode, X1/STEP can be set to RUN/STOP,X2/DIR is direction signal. X1 and X2 also
