Hello,
I have to regulate the opening and closing of a valve with the analog output 4-20 mA. I have the ATR243 driver. How do I have to act to set the PID parameters ???? What parameters do I have to change ??? I do not understand the datasheet instructions. :cry:

Hi,
the PID parameters depend of the system you are using. The ATR243 PID parameters are number 18-19-20-21. You can try to set the parameter 57.[tunE] = "Auto". The ATR243 setting the PID automatically.

Best Regards.

I think the only thing you can do is to find a servo valve with a CAN interface.

The ATR243 does not manage the CAN protocol and usually the valves do not use the CAN. The problem is only the incorrect configuration of the device and most of the time it is sufficient to activate an Autotuning to solve the problem.

Best regards.
