Hi Everyone,
I am new to srevo control, and hope to you guys can help me.
I have a Siemens s120 controler and drive, drive a cylinder up and down to supply flow rate.
It is a simple speed control with give servo the RPM speed command, I mapped the encoder vaule back to the AB plc, the value is from 0 to big number (32 bit)
I have pusles per litter information to display the actual flowrate, right now the question is that how can I monnitor the pluses change rate acrrutly?
The genetic moudle RPI for s120 controller is 20ms, I guess I can record the pluses vaule until it changes then compare them, the different will be the pluses during the 20ms, right? If this is wrong, is there a better way to do this?
Thank you!
