4.1 Structure
The devices of the b maXX 4100 series are mains inverters of Baumüller Nürnberg
GmbH. The devices convert power drawn from the mains and supply the power mod-
ule(s) connected via the DC link.
Also the devices can convert mechanical brake energy, supplied from the power modules
via the DC link, to feed it back to the mains.
The devices consist of a power unit with an integrated charging circuit and an integrated
slot for the controller cartridge. The controller cartridges itself contain, besides the firmly
installed controller (slot F), the voltage sensing module (slot A), the contactor monitoring
module (slot B), the contactor control module (slot C) and the digital I/O module (slot D)
still a few slots, which optional can be equipped.
The rated current of the devices reach from 55 A to 235 A. The devices differ in size, pow-
er, equipment (hard- and software) and cooling types.
