Hi everybody,
I never write a PID instruction before, and I just think about PID instruction to adjust the VFD hertz base on the % opening of a positional Valve. Can I do that ? If yes, where I should start ?
Let's say VFD is from 0 Hz to 60 Hz, and a actuator with (4-20mA) signal to adjust the open gate from 0 - 100% open. So if the actuator is open 50% then the VFD has to be 30Hz, how can I do it with PID instruction ?
Thanks
