S7-1500(T): Manual determination of a compensation characteristic for hydraulic valves and hydraulic axes

  • Entry
  • Associated product(s)
Description of the approach on how to determine a compensation characteristic for a hydraulic valve or axis for use with the “Axis” technology object (TO) of the S7-1500(T).

To be able to use a hydraulic axis or a hydraulic cylinder in conjunction with a SIMATIC SIMATIC S7-1500 technology object, the non-linear behaviour of the hydraulic axis or hydraulic cylinder should be linearized. The non-linearity is usually caused by the hydraulic valve.

The linearization can improve the control quality of the hydraulic axis in conjunction with the SIMATIC S7-1500 technology object. The linearization is done by means of a compensation characteristic in the SIMATIC S7-1500.
