Drive Intelligence by Baumüller b maxx10

Drive Intelligence by Baumüller – what is your most important goal?

Shorter product life cycles, growing competition – anyone who wants to survive in the international environment must minimize their development times and shorten innovation cycles. With the b maXX converters we provide you with the competitive edge with which you can achieve this.

1. Faster on the market

Faster on the market

Speed is decisive – with ProDrive, Baumüller offers a powerful tool for the commissioning and parameterization of your drives. Due to the clear user guidance, you save plenty of parameter input time.
With the drive-integrated “Smart Tuning” function the controller and processing parameters are determined and optimized automatically. The self-optimization reduces the time you expend significantly.

2. Reduce development costs

The mechanical engineering development work and costs can be lowered significantly thanks to digital tools. The parallelization of development cycles produces a considerable time advantage.

Commission your drive system virtually with ProSimulation and optimize the machine directly in the digital twin. Design and systematic errors are identified early and are corrected in advance. The Baumüller drive components are included in ProSimulation as models and enable comprehensive drive simulation.

Reduce development costs

3. Simplify commissioning

Simplify commissioning

With ProDrive a perfected tool is available for easy commissioning and operation of servo converters. Guided commissioning simplifies parameterization additionally. In particular, you can carry out the initial startup quickly due to the intuitive user guidance of ProDrive.
The consistent standardization is time-saving: The Baumüller servo drives use the ETG (EtherCAT Technology Group) standard for FSoE and support the respective standards of the individual fieldbus systems.
An optional intermediate circuit fuse makes an external intermediate circuit fuse superfluous and further reduces the commissioning effort.

4. Implement application requirements with pinpoint accuracy

From the basic device to the full fitout: Match the controller and power unit features precisely to your application. Save time and costs by only configuring and supporting what is really needed.
You can choose flexibly between different encoders, hardware and safety options. Analog and digital I/Os are also freely scalable. From STO to hardware through to higher safety over FSoE, safety applications are adjusted to the respective needs.
A large number of cooling options (air, water, oil and push-through technology) also enables drive dimensioning tailored to the application.
The intermediate circuit capacity is also scalable and, in this way, can be adjusted optimally to the application.
Components such as the ballast chopper or the brake are only included in the device if they are necessary for the application.
The charging circuit can be implemented as a thyristor infeed or as resistor charging. With the thyristor infeed, the starting frequency is unlimited and, depending on the application, the choke can be omitted.

Implement application requirements with pinpoint accuracy

5. Set up drive systems flexibly

Set up drive systems flexibly

The compatibility of all Baumüller products enables an open and scalable system architecture. You can configure the drive unit individually depending on the power and functional scope required. The modular system of the motors with different shafts, encoder options and fine speed graduation can be combined flexibly with different servo drives. In this way you achieve optimum efficiency for your application.
Baumüller systems and components can be flexibly combined with different machine controls. Our servo drives thus cover all commonly used bus systems, such as VARAN, Modbus TCP, ProfiNet IRT, EtherNET/IP, EtherCAT, and Powerlink.

6. Energy efficient

The dynamic temperature model is implemented as a new function in our servo controllers. It monitors the maximum capacity utilization of the electric drives at power peaks. As a consequence, the devices’ capacity is used better, are dimensioned smaller and, in addition to lower energy consumption, they also provide space and cost savings as well as high machine availability.
Baumüller also implements systems with intermediate circuit group for particularly high peak loads. Thus, process-related peaks can be intercepted and the electrical connected load can be significantly smaller and substantially more cost-effective.

Energy efficient

Cooling with water and oil enables simpler removal of the heat losses, lower cost for hall/control cabinet air-conditioning. The control cabinets can be made more compact.
If you opt for push-through technology cooling, the power loss in the control cabinet can be reduced. Depending on the application, there is no need for cost-intensive cooling and air-conditioning there.

7. Reduce footprint

Reduce footprint

Our new mono devices are extremely compact and are one of the most powerful on the market. The servo controllers therefore need significantly less space in the control cabinet and can be installed in an extremely confined space in the machine. The space savings therefore lead to a significantly reduced machine footprint. If you opt for water or oil cooling you can additionally reduce the installed volume.
By using the single cable solution, the omission of the encoder cable can reduce the wiring effort and save costs.
You can further reduce your control cabinet volume with an intermediate circuit group of the servo axis in combination with grid rectifier/grid inverters.

8. Maximize machine availability

Integrated process safety: Functions such as transmission protection, adaptation of the controller parameters, error reactions or monitoring the thermal pump load via a temperature model are integrated and ensure lower service costs, shorter standstill times and lower system costs.
With the parameterizable deceleration ramp (SS1-r) limits can be safely exhausted for sensitive and dangerous applications. The function integrated in the new servo controllers thus leads to higher machine reliability.

Maximize machine availability

Fast and easy assembly and dismantling of individual axis modules on intermediate circuit (link) bus, thanks to our Drive Connect System your machine stoppage times are shortened.
Use data already available with Baumüller SmartValue such as power, current, torque, speed or position, for example, to monitor the operating state of the machine. These functions can also be implemented directly in the controller even without external sensors. In addition, decisions can be taken directly in the drive so as to avoid machine failures.

9. Increase productivity

Increase productivity

Short controller clock cycles enable, for example, optimal parameterization of the gain factors and thus highly dynamic positioning.
A high field weakening range with simultaneously good control performance ensure optimal and economical drive dimensioning.
An optimal torque-to-inertia ratio of the synchronous motors, the broad speed spectrum and the overload capability enable very high clock rates.

10. Ensure product quality

Virtually cogging torque-free motors, such as the Baumüller DSH1 high-precision servo motors meet the high synchronous operation needs. If high-precision motors are not possible for performance reasons, Baumüller offers the “cogging torque compensation” function integrated in the drive, which enables uniform smooth running even at low speeds.
Highly synchronous set value settings for motion controls thanks to the real-time capable EtherCAT field bus additionally increase precision and product quality.
Oversampling in the encoder evaluation ensures maximum positioning accuracies.
Optimal open-loop control mode achieved by combination of injection, controlled and e.m.f. method ensure the correct rotational direction, a high torque from zero speed and good speed control.

Ensure product quality

We comply with Ecodesign Directive (EU) 2019/1781 for servo controllers: Our b maXX 1000, b maXX 3000, b maXX 4000, b maXX 5000, and b maXX 6000 family of converters have the required IE2 classification. The relevant data can be found in the respective instruction handbooks for the products under >> Downloads.

Single-cable solution for power and feedback systems

Less wiring effort for a compact and space-saving design

The single-cable technology fitted in Baumüller motors saves the user from having to use a feedback or an costly, inflexible hybrid cable, which is usually required in addition to the obligatory motor cable.

Unlike sensorless control, single-cable technology allows highly accurate positioning. The encoder data, rotor position, multi-turn information as well as the status of the thermal conditions in the motor are transmitted reliably and without interference via a purely digital interface. This results in considerable cost savings, as there are no connectors or cables on the motor or controller side. Cost-intensive analog evaluation modules in the drive are unnecessary.

Diagnostics are also a possible option. Wiring is greatly simplified, which eliminates possible sources of error and also has a positive effect on the peripherals, since drag chains, cable bushings and areas reserved for the cables in machines and control cabinets are now significantly smaller.

The new technology supports an “electronic type plate”. On the motor side, this results in a greater degree of freedom: Eliminating the plug-in connection allows the new technology to be used even in the smallest sizes.
