Technology CPUs: Technology Template "Hydraulics Characteristic"

  • Entry
  • Associated product(s)

Problem
If a hydraulic axis is to be operated through the control loop of the technology CPU you need a compensation characteristic  for optimal control., which maps the linear actuating signal of the controller onto the non-linear behavior of the hydraulic axis.

Solution
The technology template can be directly used for the measurement of the compensation characteristic of a hydraulic axis and for the activation of this characteristic in the control loop of the technology CPU.
