Thanks to the flexible linking of analog inputs and digital setpoints (e.g. MIN, MAX, POL, kinked gain characteristics), the modules can be optimally adapted to a wide variety of valve types and applications in mechanical engineering, vehicle construction and industrial automation. Parameterization is conveniently carried out via software tools such as WPC-300, supported by integrated diagnostics and extended functional testing for maximum operational safety. In the Hydromot online shop you will find high-performance setpoint modules such as the DSG-111 series (e.g. DSG-111-U and DSG-111-P) – digital, flexible and generally available at short notice.

 

Setpoint Modules in Control Technology – Frequently Asked Questions

What are setpoint modules and what is their main function?

Setpoint modules are electronic units used in hydraulics and control engineering to define and regulate control variables such as pressure, speed or position.

Their main function is to generate setpoints that serve as reference values for control loops, for example for actuating proportional valves in hydraulic systems.

How can setpoints be adjusted or programmed on these modules?

Setpoint modules are typically parameterizable and allow analog or digital entry of setpoints.

Adjustment is usually carried out via potentiometers, digital switching inputs or a combination of these. Many modules can store multiple setpoints (e.g. up to 16 setpoints and ramp times).

Parameterization is often supported by software tools or configuration interfaces, which simplifies commissioning.

What advanced functions do setpoint modules offer for signal processing and signal linking?

Many setpoint modules have integrated functions for signal processing and linking of analog and digital signals.

Typical functions include:

  • Multiplication (*)
  • Division (/)
  • Addition (+)
  • Subtraction (-)
  • Minimum (min)
  • Maximum (max)

This allows input signals to be flexibly combined and adapted to different control tasks.

What are ramp functions and what advantages do they offer in operation?

Ramp functions serve to apply setpoint changes over a defined time, creating smooth acceleration and deceleration profiles.

Modern setpoint modules can provide four-quadrant ramps, enabling jerk-free force and movement control – both during acceleration and braking in both directions.

This reduces mechanical stress, protects components and contributes to longer system life.

What is the significance of valve adaptation in setpoint modules?

Valve adaptation enables the adjustment of the setpoint module to the characteristic curve of the valve, ensuring reproducible control behavior.

This includes compensation functions, e.g. to correct dead bands (MIN, MAX, POL) or to linearize nonlinearities.

Some modules support additional features such as a overlap jump or a kinked gain characteristic, to match the output signal to the behavior of the respective proportional valve.

Where are setpoint modules typically used?

Setpoint modules are used in various areas of automation and drive technology, particularly in hydraulic and electrohydraulic systems.

Typical applications include:

  • Control of directional, throttle and proportional valves
  • Regulation of pump and motor functions
  • Fast/slow travel control
  • Time- or sequence-controlled motion profiles

Common fields of application include mechanical engineering, vehicle construction, industrial automation and mobile machinery.

Which criteria are important when selecting a suitable setpoint module?

When selecting a setpoint module, several technical and application-specific criteria should be considered:

  • Type and number of setpoints (analog, digital, programmable)
  • Type and number of inputs and outputs (digital switching or analog inputs, potentiometer inputs)
  • Compatibility with the valves or actuators used
  • Available ramp, processing and linking functions
  • Degree of protection, housing material and suitability for the intended environment
  • Support via configuration software and diagnostic functions if applicable

How are setpoint modules constructed, and what must be considered regarding maintenance and protection?

Setpoint modules are usually housed in compact metal or plastic enclosures designed for industrial or mobile environments.

Because they are electronic components, they are largely low-maintenance in operation. However, adequate protection is important against:

  • Mechanical stress and vibration
  • Moisture and contamination
  • Strong electromagnetic interference fields

Proper installation and consideration of environmental conditions significantly contribute to a long and trouble-free module life.
