Resolution and Maximum Speed Tables - Quadrature Output
Mercury II 6000 systems (models 6500/6700/6800) have programmable interpolation from x4 to
x16384 in integer steps. Below are tables of sample values. For applications requiring up to
10m/s at full resolution, use the MII6800Si/Pa with high speed serial interface.
