Me neither, BTW they already bought it. I do not know why i never recommnended to do it.You didn't explain the speed limit of 123mm/s. Is that the line speed?
No, that´s cylinder speed i.e. saw speed to cut the pipe, carriage is another story , carriage speed is max 25 m/min that part is driven by same Controllogix PLC but thru a servo motor and inline encoder, that part is working properly.

Thanks for the link , I´ll take a closer look.
If hydraulic cylinder is for the saw, is precise positioning required? I know the M02AE position should be precise.
Well, I would say just to cut the pipe and then return, I´d say +/- 1 cm.
BTW, I have canned programs for flying cut off saws or shears.

With a RMC you can test your program at your desk.
Yes. I have your software installed in my computer. No doubt i will do it.
I still don't like the valve.
Sorry for the confusion, but finally all I talk about this time is only for saw.
As i said before, nowdays that saw is being driven by a bang bang valve, they use limit switches to indicate both ends of stroke. They have to move them every time they change pipe diameter, and they want to change that. They want to do it by software that´s the reason for a servo control.
I forgot to mention that maximun pipe OD diameter is 6" minimum OD 3", that means that maximum stroke would be aprox 8.5" and minimum 5.5" not 16", that is maximum stroke of cylinder.
If you need extra info or explanation, I´ll be here.
