Hello folks,
For a new test setup (a servo drive), I consider to use a Heidenhain encoder (e.g. ECN 425) with the propriety EnDat 2.2 interface, which in turn will be hooked up to a cRIO 9068 using a SEA 9510 c-series module.
Some info on the module and the interface can be found here:

My plan is to sample the encoder position every 30-40 micro-seconds and calculate the shaft speed numerically in the FPGA with the highest possible bandwidth, which most likely is limited mainly by time jitter on the position sampling instant.
Before making the final purchasing decision, however, I just would like to ask if anyone has good or bad practical experience with the Heidenhain (EnDat 2.2) / SEA 9510 combo?
Integrating third party stuff can be a hassle from time to time, and any feedback will be highly appreciated.
