Measuring function

The measuring functions can be used to evaluate the most important velocity and position
control loop variables in the time and frequency domain on a screen without having to use
external measuring equipment.
An overview of the measurement functions provided for HLA is given below. Only the
hydraulic-specific functionality for HLA is described in detail.
The following measurement functions can be performed in conjunction with the HLA:
● Valve control loop measurement
– Valve frequency response
● Velocity control loop measurement
– Reference frequency response
– Setpoint step change
– Disturbance frequency response
– Disturbance step
– Velocity controlled system
– Velocity control system + controller
● Position control loop measurement
– Reference frequency response
– Setpoint step change
– Setpoint ramp
Note
The figures show the basic response. Measurements on real valves may deviate from this.
