Leonardo,
I agree with Peter and he is truly the expert..
I have done both platforms and I really like the HYD02 coupled with RSLOGIX 5000.. As Peter indicated, you need to verify compatibility with the rods you are going to use. I have had good success with Balluff but MDT work well too.. I don't think that you could go wrong with either one..
The QS used M files coupled with the IO Image Table.. In regards to the HYD02, you will need to flash the processor and HYD02 card to the latest-compatible firmware version. After doing that, you will need to add a motion group and then add a new axis. Once you schedule the axis, it will appear and be active.. You will need to scale the rod feedback via conversion constant so your length measurement will be correct..The axis will look and feel just like a servo drive.. RSLOGIX 5000 will allow you to construct trends so you can perform tuning... In order to clear a fault on the axis, you can issue a MAFR.. In order to enable the axis, issue a MSO and in order to send a move command, issue a MAM.. The MAM will allow you to pick an S-Curve or Trapezoidal Profile Move.. Also, you can trend position and velocity for tuning..I think that after doing the QS, you will think that the HYD02 is easier to implement.. Once you set them up and get them running, they are really solid cards.. So, good job Peter!!!!
