Fig. 73: DC-supported micro-increments
The highly constant query cycles (accuracy: 100 ns) of the distributed clocks systems enable the EP51x1 to
interpolate axis positions between the counted encoder increments from a certain speed. The interpolation
resolution is 8 bit, corresponding to 256 values. A standard encoder with 1,024 lines with 4-way evaluation
and micro-increments thus becomes a high-resolution axis encoder with 4096 x 256 = 1,048,567 lines.
If the velocity value falls below the minimum value, this is indicated by the object Extrapolation stall
0x6000:08 in the process data (not for EP5101-2011).
