HYDAC Rotary Drive Control Tried-and-tested hydraulics combined with intelligent control technology

Rotary Drive Control is a clever type of speed control for your mobile machine. This is because electro-hydraulic systems require high precision, especially in the case of increased environmental protection or when there are new regulations. Wherever there is a need for speed-controlled functions combined with high power densities, the Rotary Drive Control operates with extreme precision and dynamic performance thanks to the electronic control. For the best performance of your mobile machine – even with pressure fluctuations.

Rotary Drive Control – highly dynamic speed control for your mobile application

Precision & stability
Accuracy despite pressure fluctuations and parallel consumers

Modern machines are a reflection of the technological development in the industry. They increasingly combine high efficiency with precision and dynamic performance. Hydraulic machines in particular have a high power density which needs to be controlled to achieve the best results. These technical developments mean that high accuracy and stability despite influences such as pressure fluctuations and parallel consumers are increasingly gaining in importance.

Stricter legislation and environmental protection
Resource-saving use of fertilizer and grit

The increasingly strict legal requirements in terms of environmental protection, consumer protection and the resource-saving use of fertilizer and grit are extending the specification profile of mobile machines. To meet these increased demands, individual functions which are designed to be as dynamic and needs-based as possible are becoming increasingly important. This requires modern control technology.

Increasing energy costs and raw material costs
Reduction in wear, energy and material costs

Increasing raw materials prices, especially for fuels and work equipment, are weighing heavily on machine operators. For this reason, resource-saving machine operation is becoming more and more important. The focus is on needs-optimised work flows and material conservation. Consistent and stable drives can make a significant contribution to reducing wear and lowering energy costs and material costs.

Our solution: dynamic and precise speed control
The HYDAC Rotary Drive Control system at a glance

The HYDAC Rotary Drive Control uses hydraulic components to enable highly dynamic and precise speed control. Our approach combines the advantages of tried-and-tested hydraulic and electronic system components with those of modern machine controls. In this way, hydraulic machines are able to reach their full potential. The result: a machine drive that provides large forces whilst adjusting these to the particular requirements with high dynamic performance and precision. The subsystem is compatible with all common constant pressure systems and load-sensing systems. It also offers a standardised protocol for CAN-based communication with the machine control and the HYDAC Machine Service Tool (MST).

The Rotary Drive Control essentially consists of the following components:

  • Hydraulic motor
  • Valve technology
  • Speed sensor
  • Controller with application software

Your advantage – stand-alone subsystem
Your stand-alone subsystem for the best results

Rotary Drive Control regulates the impact of influences such as pressure fluctuations or parallel consumers on the machine functioning. As a stand-alone subsystem, the HYDAC solution fits seamlessly into the hydro-mechanical drive train, enabling the best results. The RDC is therefore extremely well-suited to the development of your mobile machines with decentralised individual functions.

Your advantage – automatic calibration
Automatic calibration as the key to success

An essential element of the Rotary Drive Control is automatic calibration of the system. For this, the rotary drive performs a sequence while the individual behaviour of the hydro-mechanical drive train is detected. The resulting system characteristics are stored in the control system and used to optimise the control behaviour. In this way, time-consuming coordination of the machine function during commissioning or maintenance is no longer necessary.

Your advantage – custom user interface
All data at a glance with the HYDAC user interface

In terms of function optimisation and maintenance, it's helpful to have all system-relevant data available at a glance. With the Machine Service Tool (MST), HYDAC offers you a user interface for this exact purpose. With the MST, parameters can be modified and measured values can be read. Errors can also be diagnosed and system functions can be tested.
