In the field of precision automation and motion control, Baum ü ller from Germany is renowned worldwide for its outstanding drive technology. The b maXX 3300 series servo controller is designed for applications in the low power range (up to 5 kW), making it an ideal driving core for robots, packaging machinery, printing equipment, and textile machinery with its compact size, excellent dynamic response, and rich integrated functions. Model BM3401-LIFBO-ACOOOCB-G-02-O-02 is a typical representative of this series that supports single cable solutions, has built-in safety features, and is equipped with mainstream bus interfaces.
Excellent control performance and compact design
The b maXX 3300 adopts magnetic field oriented control technology, providing extremely short sampling times for the current loop (62.5 µ s), speed loop (125 µ s), and position loop (125 µ s), ensuring extremely high speed accuracy and positioning accuracy of the motor operation. Its compact body (with a width of only 65-108mm) greatly saves control cabinet space, while supporting a maximum switching frequency of 16 kHz, effectively reducing motor operating noise and improving the working environment.
This controller is specifically designed to adapt to Baum ü ller DSD 28-100 series dynamic servo motors, disc motors, and linear motors, forming a perfectly matched drive system that significantly improves the production cycle and output efficiency of the machine.
Flexible encoder and single cable technology
The b maXX 3300 supports almost all mainstream encoder types:
Resolver (Rotary Transformer, Resolution 1024 inches/r)
Incremental rectangular encoder
SinCos sine cosine encoder (including Hiperface, EnDAT 2.1/2.2, SSI interface)
Absolute value encoder (single/multi turn)
Specifically, the controller is compatible with Hiperface DSL single cable solution - only one hybrid cable is needed to simultaneously transmit power and feedback signals, greatly reducing wiring workload and fault points. It also supports electronic nameplate automatic recognition of motor parameters for fast debugging.
Integrated security technology: STO to PLe
Safety is of paramount importance in modern mechanical design. The b maXX 3300 comes standard with certified Safety Torque Off (STO) function, which complies with EN ISO 13849 standard and can reach up to PLe safety level. Without the need for an external contactor, the motor torque can be cut off, simplifying the safety circuit design and reducing system costs.

Powerful communication and intelligent control
The controller board is equipped with EtherCAT and CANopen fieldbus, which can be seamlessly integrated into various automation networks. In addition, the b maXX 3300 supports softdrive PLC functionality (basic and extended versions), allowing users to directly execute PLC logic tasks within the controller without the need for additional control hardware. The extended version is fully integrated into the ProMaster engineering framework, supporting PROPROG 5 programming, cam editor ProCAM, etc., to achieve distributed intelligent control.
Convenient parameterization and diagnostic tools
Through ProDrive parameterization software (supporting German/English), users can perform guided debugging, online/offline parameter settings, multi axis operations, and oscilloscope/FFT analysis functions. The integrated electronic nameplate reading and automatic updating of the motor database greatly simplify the maintenance and spare parts replacement process.
