NOTE
• The scale travel is detected in 200 ns increments and output at a phase difference
proportionate to the amount traveled.
• The phase difference changes in integral multiples of 200 ns.
• When the scale has following condition, A/B signal are placed in the high impedance status.
• Phase difference of A and B signal is narrow than min phase difference time.
• Scale signal is small compare with specified value.
• Malfunctioning has occurred due to external noise or some other reason.
