Hello, for getting the compensation characteristics of a valve manually, you could read the following FAQ: S7-1500(T): Manual determination of a compensation characteristic for hydraulic valves and hydraulic axes And for using this characteristics, you could read the following application example: Using the MC-PreServo and MC-PostServo organization blocks While using the FAQ and the application example, it is not necessary to use a PID control. For this, it is maybe possible, to use TO PositionAxis directly for controlling the valve... Maybe, it will help... - But I don't know, if it also works with S7-1200. |
