Drive Intelligence by Baumüller

The Baumüller servo drives are available as controller models for simulation in the ProSimulation software. You use this data to design the optimal automation and drive components for your machine and test the settings, without risk, virtually – all possible from your desk, even without detailed simulation knowledge.

Baumüller offers innovative software tools for simulations such as MapleSim and MATLAB/Simulink as an engineering service for the digital twin. Modeling and simulation make it possible to design and simulate the optimal drive and automation components for various machines. The so-called digital twin already maps the expected machine behavior in the development stage, even though the machine is actually not (yet) available in reality.

With ProDrive, a tool is available which simplifies commissioning, parameterization and operation of all b maXX controllers through graphic user guidance — for the novice and for the professional. In particular, you can carry out the initial startup quickly due to the intuitive user guidance of ProDrive.

The safe servo controller, mountable side-by-side

Baumüller sets standards with its b maXX 5000 servo generation. The consistent enhancement of the successful b maXX series in the direction of module systems impresses with high-performance power units with air, water and cold plate cooling, flexible expansion capability and connection to an integrated communication concept. With Baumüller converters and controllers within the power range from 1 to 100 kW, both standardized and complex automation solutions are possible. The machine and plant requirements regarding future-proofness, flexible expandability and easy changeover to changing production processes were already taken into consideration during the development of the b maXX 5000.

b maXX 5000 has an integrated drive connect system: Individual modules can be simply removed and integrated, without having to under the complete drive system. The standard-setting control quality is ensued at all times.

Powerful mono units in seven sizes

The 5000 series inverters have been extended to mono units in the 5500 series. With the b maXX 5500, higher safety functions such as SLS (safely limited speed) and SLP (safely limited position) can be integrated into high performances.

Intelligence in the drive

The intelligent converters of the Baumüller b maXX 5000 product family with integrated softdrivePLC enable data analyses directly in the drive. In this way, logic operations cannot only be parameterized, but also be programmed. An example: If the control circuits vibrate due to resonant frequencies, this vibration can be minimized with the help of a more dynamic setting and productivity is increased. Vibrations in the mechanics can also be filtered out with the intelligent b maXX converters.

Numerous controller functions are integrated in the b maXX 5000 series, to make the system even more efficient and intelligent. Functions such as transmission protection, adaptation of the controller parameters, error reactions or monitoring the thermal pump load via a temperature model ensure lower service costs, shorter standstill times and lower system costs.

b maXX 5000/3000 – single cable solution for power and feedback systems

Less wiring work for compact and space-saving design

The single cable technology, with which Baumüller motors are equipped, not only saves the user the obligatory motor cable, but also the usually required feedback or an expensive, inflexible hybrid cable.

Unlike sensorless control, high-precision positioning is possible with single cable technology. The encoder data, rotor position, multi-turn information and the status of the thermal conditions in the motor are transmitted, fail-safe and reliably, via a purely digital interface. This results in significant cost savings, since it removes the need for plug-in connectors and cable at both the motor and the controller end. There is no need for cost-intensive, analog analyzer devices in the drive booster.

Diagnostics are also possible. The wiring is simplified significantly, which eliminates potential sources of error and also has a positive effect on the peripherals, as mobile cable handlers, cable glands and areas in

Machines and control cabinets reserved for the cables are significantly smaller.

The new technology supports an “electronic type plate”. This results in greater degrees of freedom on the motor side: The removal of a plug-in connection enables use of the new technology in even the smallest sizes.
