From the standpoint of energy costs, this offers the

user considerable savings over the machine’s service

life. Regenerative systems help to lower energy con-

sumption (and do their bit for the environment) by

feeding the available brake energy back to the power

grid rather than wasting it via a regenerative resistor.

The b maXX 4100 units are fully integrated into

Baumüller’s b maXX automation and drive solution

family of products. The benefits which the b maXX

series offers to its users such as modularity and

flexibility, are also provided by the b maXX 4100.

Four different frame sizes cover a DC link power

range of 35 kW to 150 kW with the option of air

or water cooling. The b maXX 4100 can also be

integrated in the Baumüller automation environ

ment by means of various optional fieldbusses.

System consistency is achieved by adopting the

same housing technology and connection arrange

ments as well as integrating the parameters of the

b maXX 4400 into the existing b maXX ProDrive

operating software.
