Ri speed
Clocked outputs
Ri0100, Ri0200 and Ri0400 interfaces have clocked outputs.
Customers must ensure they comply with the lowest recommended counter input frequency.
Non-clocked outputs
Ri0004, Ri0008, Ri0020 and Ri0040 interfaces have non-clocked outputs.
Angular speed
Angular speed depends on disc optical diameter – use the following equation to convert to rev/min:
Angular speed (rev/min) =
V × 1000 × 60
p D
where V = maximum linear speed (m/s) and D = optical diameter (mm)
