Note: *Maximum speed produces an encoder quadrature output of 50 million states per second

(12.5MHz). See Page 24 for additional output frequencies. Maximum speeds shown above will be

reduced if a lower quadrature output frequency is selected.

Note: **Resolution values shown are approximate. To calculate exact resolution values, convert from

CPR (Counts per Revolution) to the desired units.

Note: To calculate desired rotary interpolation multiplier, use the following equation:

𝐼𝑛𝑡𝑒𝑟𝑝𝑜𝑙𝑎𝑡𝑖𝑜𝑛 𝑀𝑢𝑙𝑡𝑖𝑝𝑙𝑖𝑒𝑟 =

𝐷𝑒𝑠𝑖𝑟𝑒𝑑 𝑅𝑒𝑠𝑜𝑙𝑢𝑡𝑖𝑜𝑛 (𝐶𝑃𝑅)

𝐹𝑢𝑛𝑑𝑎𝑚𝑒𝑛𝑡𝑎𝑙 𝑆𝑐𝑎𝑙𝑒 𝑅𝑒𝑠𝑜𝑙𝑢𝑡𝑖𝑜𝑛 (𝐿𝑖𝑛𝑒𝑠)

Note: Specifications assume XOR function which is available in all standard controllers.
