Stackable, flexible and energy-efficient converter
With the b maXX 5000 generation of converters, Baumüller is setting new standards. The consistent enhancement of the successful b maXX series in the direction of module systems impresses with high-performance power units in the cooling methods air, water and cold plate, flexible expansion capability and connection to an integrated communication concept.
Both standardized and complex automation solutions are possible using Baumüller converters and controllers in the range of 1 to 100 kW. The requirements for machines and plants in terms of future-proofing, flexible expandability and easy conversion to changing production processes were already taken into account in the development process of the b maXX 5000.
b maXX 5000 features an integrated drive connect system: Individual modules can be easily removed and integrated without having to remove the entire drive system. The standard-setting control quality is guaranteed at all times.
- plug-in module, available with or without safety functions
- Three different safety modules with scalable functionalities
- All modules with integrated parameter memory for secure and non-secure data
- Safety functions in accordance with IEC 61800-5-2
- Power output for motor brake
- Selection of safety functions via local safe I/Os or EtherCAT FSoE
Power supply units for high performances
The converter series b maXX 5000 includes rectifier and regenerative feedback units as well as drive units, which can be quickly and easily combined by an integrated drive connect system. This allows the machine builder to benefit from low installation costs and short commissioning and service times. The controllers are available in the cooling methods of air, water and oil and, thanks to their high power density, boast a very small installation space.
The power supply units have been expanded to include peak outputs of up to 300 kW. Ideal for dynamic movements requiring high peak outputs at short notice. With a peak current of 420 A, the large axes are ideally suited for maximum dynamic performance.
The energy-efficient solution scores with its very compact design and high power density and precision.
Integrated safety functions in the power supply unit
For the b maXX 5000 generation of side-by-side converters, Baumüller offers a new safety solution in which the electric motors are switched off centrally with an STO (Safe Torque Off) module integrated in the power supply unit rather than decentrally in the individual motor converters.
As standard, the safety function in drive systems is integrated decentrally in the individual motor current converters. Equipping the electric motors with only one centrally switched STO control unit reduces the installation and wiring complexity of the drive system, resulting in lower manufacturing costs.
The new safety concept meets the SIL 2 safety requirements according to IEC61508 / PLd, category 3 as per DIN EN ISO 13849-1 and can be used in all applications where the power supply unit and the axis units require the same STO conditions.
DC link capacitance unit for the b maXX 5000 series
Energy and cost savings for dynamic applications
With the DC link capacitance unit, the braking energy can be temporarily stored for dynamic applications and used for subsequent acceleration. Applicable with devices of the b maXX 5000 converter generation.
- Intermediate storage of braking energy –› Lower and optimized energy consumption
- Peak load leveling –› Reduction of the contractually agreed consumption peaks with the energy supply company
- Lower thermal radiation –› Smaller dimensioning of the cooling units possible
- Smaller dimensioning of the control cabinet and power supply unit –› Less space required and cost savings possible
- Temporarily stored energy allows for controlled system shutdown in the event of errors and power failure –› Cost reduction by not needing an independent power supply (UPS)
b maXX 5000 – The modular servo drive
The control of a brake resistor is integrated in the device as a brake chopper. A ballast resistor is connected externally. On the one hand, this ensures optimum dimensioning and, on the other, reduces the construction volume of the control cabinet.
To ensure a cost-effective configuration, mains filters are always connected externally upstream of the device. This way, several power modules can be combined on one mains filter, which reduces the costs for the entire system.
Temperature-dependent fan control
The fan is open-loop controlled as a function of the internal temperature of the device. This lowers the overall energy balance, thus reducing the overall costs of a system.
DC link coupling
A DC link coupling of several power modules for energy compensation is possible. The excess energy is not “burned up”, but is available to other drive units without additional energy being absorbed from the power supply.
With the help of the optional safety module, “STO” functionality acc. to EN ISO 13849 up to PLe/SIL3 can be easily realized without integrating additional contactors within the motor cable. This makes the structure of the safety circuit simpler and clearer. The potential danger emanating from the machine is reduced. The machine works reliably.
The modular servo system for outputs up to 100 kW
The modular servo system sets standards in drive technology. In combination with the four available servo motor series DSD2, DSP1, DSH1 and DSC1 you always get the exact performance you want – no more and no less
