precise | scalable | energy-saving

2 Power on demand

Intelligent pump control system provides power on demand

Optimum power density, impact and overload robustness, force holding without consuming energy: Hydraulics have numerous physical advantages which make them valuable to mechanical engineering. With a broad range of control systems, Rexroth taps into state-of-the-art automation for hydraulic drives. Here, the experience gained through thousands of applications is particularly valuable. Our expertise considerably simplifies engineering and ensures quick, flexible and reliable solutions.

3 Power on demand

The SY(H)DFE electro-hydraulic pump system for the precise and dynamic control of pressure and flow on demand as well as for power limitation, is based on Rexroth's extensive, tried-and-tested range of A10 and A4 axial piston pumps. The stepless adjustment device of the pump and, if required, also of the drive motor, functions like a hydraulic gear. The system opens up new degrees of freedom regarding energy efficiency, precision and flexi-bility. Thanks to reduced throttling losses in the hydraulic system and the closed-loop speed control of the pump drive, users save up to 80 percent of energy compared to constant systems.

The software by Rexroth is based on tens of thousands of applications and automatically compensates for all the special requirements of fluid technology. With analog or open interfaces to CANopen and all commonly used real time Ethernet protocols, the hydraulic system by Rexroth can be seamlessly integrated in state-of-the-art machine designs.

SY(H)DFE control pumps have proven to be extremely robust and versatile with over 250,000 installed units. Through continuous further development, Rexroth created a modular solution which ensures that the pumps, which are finely scalable regarding function and power, fulfill the requirements of many different industries: Plastic machines, presses, metallurgy and special machinery.

Scalable functions for individual applications

Scalability

During continuous further development, a modular system was created which opens up high degrees of freedom for designers to tailor SY(H)DFE control systems precisely to the requirements of their application regarding function and power. At Rexroth, “scalable” stands for a broad selection of different pre-configured pump sets. The DFE pump systems are based on the extensive and powerful axial piston pump program by Rexroth.

▶ The broad range of pump versions with various electronics (analog or digital, on-board or remote) and standardized mechanical and electrical interfaces allows for flexible use.

SYHDFE NG355

SYDFE NG18The base pumps are A10VSO of series 31 and 32 with a pres- sure range up to 280 bar and A4VSO for the high pressure range with up to 350 bar permanent pressure. Rated vol-umes of 18 to 355 ccm cover a broad power spectrum. Due to their universal through-drives, A10 series 32 and A4 pro- vide various possibilities for combining the pumps, accord-ing to the application.

Ideally suited for retrofitting applicationsEven systems which are already installed can work in a more precise, dynamic and energy-efficient manner after retrofit-ting with a SY(H)DFE control system. Electric motor, pump, coupling, piping, pump carrier and pressure sensor remain unchanged. Only the high-response valve with on-board electronics and swivel angle sensor have to be exchanged. After commissioning with help of machine control and the IndraWorks DS or WIN-PED software, the pressure and flow control system is immediately ready for operation and pro-vides enhanced control accuracy and energy efficiency.

▶ Thanks to different through-drive versions, several pumps can be connected. In this way, users can combine the pumps from the broad Rexroth portfolio in almost any way

8 Engineering using IndraWorks

Rexroth has gathered unique knowledge of the interaction between hydraulics and Motion Control technology. Based on this knowledge, the control strategies for hydraulic and hybrid drives have been optimized by our software engineers. They follow one simple principle: plug and produce.

Switch on, parameterize and start

The large number of electrical and standardized mecha-nical interfaces ensures easy integration into various machine designs. From parameterization to commissioning to diagnosis, the intuitive engineering tool IndraWorks accelerates the process of developing an individual drive solution. The consistent engineering environment for all Rexroth systems standardizes the handling of PLC, Motion and all drive technologies.

A large number of freely accessible parameters, down to the controller structure, allows for precise setting of the system. In connection with the parameter change, it is possible to optimize various processes in a highly precise manner. Thanks to the integrated automatic calibration, the control behavior of the SY(H)DFE systems can always be reproduced. Zero point drift of the pressure sensor, swivel angle offset, valve offset and pump leakage are corrected automatically in this function. The data recorded in this process are made available via the digital communication interface. The data can be used for condition monitoring in the machine control. Users detect wear earlier and are able to plan targeted maintenance measures to prevent machine downtime.

Through parameter changes alone, the hydraulic gear step- lessly provides various working points and considerably simplifies the change-over to new tasks. One touch of a finger is enough

10 Hydraulic Gear

Hydraulic Gear: Energy conservation, noise reduction, downsizing

The combination of closed-loop speed control and swivel angle adjustment of the pump opens up new energy conservation possibilities. And that's not all: The steplessly adjustable “Hydraulic Gear” system requires significantly lower installed power.

In connection with the variable speed pump drives, the power consumption of hydraulic systems is reduced by up to 80 percent when compared to constant systems. The decisive parameter is the time share of partial load oper-ation in the cycle. The SY(H)DFEn software constantly calculates the optimum combination of swivel angle and speed for the entire drive train on the basis of the required pressure. With the pressure drop between high-pressure and low-pressure side and with the swivel angle or the

stroke volume of the pump, the pump torque increases. The volume is proportional to swivel angle and drive speed. With a swivel angle of zero, the displacement is zero. This reduces the torque required of the motor to a minimum. The reduction of the torque at low flow and the swiveling back of the variable displacement pump during pressure-holding operation reduce the motor load.

In addition, the closed-loop speed control also reduces the mean noise emissions by up to 20 dB(A). In this way, sec-ondary noise protection measures can often be omitted.

The result: In numerous applications SY(H)DFE systems do not only consume significantly less energy. In addition, an electric motor of a smaller frame size is often sufficient. The downsizing reduces the system costs and further re- duces power consumption.

◀ Downsizing using a press drive as an example: With the same working capacity, the installed power of 37 kW of a fixed displacement pump is reduced to only 11 kW with an SY(H)DFE solution. The power limitation protects the motor against overload P(kW) = Q(l/min) · p(bar) : 600

SYDFE1With the analog controlled SYDFE1, the electronic card VT5041 is installed separate from the pump in a control cabinet. This means that this variant is particularly suited for use in harsh environments, at high temperatures up to 60 °C or under oil. To exchange the electronics, no work at the pump is required.

SY(H)DFEE – analog on-board electronics The electronics integrated in the pilot valve reduce the wiring effort. The very short lines also reduce the effort for EMC measures. Rexroth supplies the system as completely mounted and adjusted units which are ready for installation. This variant is designed for high ambient temperatures of up to 60 °C.

SY(H)DFEC – digital on-board electronicsThe advantages of analog and digital connection via CANopen are combined by SY(H)DFEC. With the automatic calibration and a parameterizing software incl. scope func- tion, it simplifies commissioning and maintenance. The signal exchange with the control system is either analog and/or via a CANopen interface. With all systems, multi-circuit and master/slave variants can be built either using multiple pumps or combinations of several motor pump groups.

SY(H)DFEn – variable-speedBased on a digital SY(H)DFE system, the signals are ex- changed with the control system via analog and CANopen interfaces. Identical mechanical interfaces allow for the simple modification of a SY(H)DFE to a variable-speed SY(H)DFEn system. A lower speed within the partial load range re- duces the energy losses and noises from pump and electric motor. The SY(H)DFEn control system, combined with a standard frequency converter, additionally reduces the speed while controlling pressure and delivery volume when the flow demand is low.

The speed command value for the frequency converter is calculated in the OBE.
