Resolution of rotary analog encoder
 Resolution of rotary analog encoder
Normally the line number of one revolution is indicated by the output sine
waves and cosine waves. For instance, HIWIN direct drive motor (TMS32)
outputs 3600 sine waves and cosine waves for one revolution. The line
number is 3600 line/rev. If analog encoder multiplier factor is 250, the actual
resolution is:
3600 / × (250 × 4) = 3600000 /

 Resolution of linear digital encoder
If Renishaw digital encoder is used, the displayed resolution of the reader is
1 um. The resolution is:
1  ÷ 1000 = 0.001 
