New generation of the tried and tested servo-converter – Nr. 10/2011 (28.11.2011)
The new b maXX 3300: more compact, more safe, more economical

Nuremberg. "be in motion" – Baumüller has developed the tried and tested b maXX 3400 servo-controller further precisely in accordance with this motto and is therefore presenting the new generation of high-quality servo-controllers for small drives in two sizes and with the optional manual operating unit in this new b maXX 3300. Compactness, high levels of dynamics and energy efficiency are the significant characteristics of this new servo-converter.

As was the predecessor b maXX 3400, the new b maXX 3300 has been designed with an integrated position regulation for the lower power range, up to five kilowatts, for example for applications in the fields of packaging, textiles, robotics and material handling. Baumüller customers will, in the future, benefit particularly from the compact design. Another innovation is the implementation of the safe torque switch-off facility, referred to as STO (Safe Torque Off) in brief. This function ensures that, in the event of an emergency, the supply of energy is stopped, and thus a rotary torque force is not created. Consideration of the guidelines EN ISO 13849 and EN 62061 by integrated safety up to SIL 3 (Safety Integrity Level) and PL e (Performance Level) means that "Safety first" is no longer just a notional concept, but rather it is realised in the b maXX 3300.

The user continues to benefit from field-oriented regulation providing exceptional concentricity and higher level speed and position regulation for dynamic and precise positioning. The b maXX 3300 is designed, as was its predecessor, for operation with servo-motors DSD and DSC, up to size 100, and the Baumüller disc and linear motor ranges, amongst others. The cycle time for applications and thus the production rate of machines and installations is increased.

This increases the benefit for the customer, particularly in the packaging and textile industries and in the small robot and materials handling sectors. The environment benefits from the higher cycle frequencies up to 16 kilohertz, which facilitate more precise regulation and which considerably reduce noise emission from the machine and thus reduce environmental loading.

The manual operating unit, available as an option for the b maXX 3300, allows the user full access to all parameters, without the need for ancillary external components such as a PC and software. This facilitates both rapid service access and uploads and downloads of data sets.

The b maXX 3300, along with all the converters in the b maXX range, facilitates demand-compliant design of the drive system. The consistency with the b maXX regulators 4000 and 5000 underscores this characteristic. The parametrising software ProDrive in the Engineering Framework ProMaster provides for convenient parametrisation.
