Number Of Divisions And Output Phase Difference - Sony MJ620 Instruction Manual

3-3. Number of divisions and output phase difference

The MJ620 output A/B phase signals, an alarm signal, and reference point signals as shown
in Fig. 3-1.
Minimum phase difference: Tw: 100 ns (When set to a minimum phase difference of 100 ns)

. The encoder travel is detected in 100-ns increments and is output at a phase difference
proportionate to the amount traveled.
The phase difference changes in integral multiples of 100 ns.
. The A/B phase signals are at high impedance during output of the alarm signal.
