What exactly is CUI's definition of "PPR"? "Pulses Per Revolution" is ambiguous.
Do they define it as
- rising edges per rev on one channel?
- rising and falling edges per rev on one channel?
- rising and falling edges per rev on both channels?
Couldn't find the term defined unambigously anywhere on the website or in the product datasheet.
Note: US Digital rates their encoders according to CPR, which they define as "Cycles Per Revolution", which is unambiguous. For example, a US Digital 360 CPR encoder would mean 360 cycles per rev, which is the same as:
360 rising edges per rev per channel
720 rising and falling edges per rev per channel
1440 rising and falling edges per rev both channels
