Maximum response speed 1200 mm/s (at two-phase sine wave output)
For a two-phase square wave, the value changes depending on
the resolution as follows (when the minimum edge-to-edge interval
is 125 ns):
0.1 μm: 720 mm/s
0.05 μm: 360 mm/s
0.02 μm: 144 mm/s
0.01 μm: 72 mm/s
* When the minimum edge-to-edge interval doubles, the maximum
response speed halves.
