• Input format command pulse
• PULS and SI GN represents the outputs of pulse train in put circuit. Refer to the fig. of P.3-30, "Input Circuit".
• In case of negative direction pulse train + positive direction pulse train and pulse train + sign, pulse train will
be cap tured at the rising edge.
• In case of 2-phase pulse, pulse train will be captured at each edge.
