BAUMULLER b maXX 4400 – The modular servo controller

Braking energy

Brake resistor activation is integrated in the form of a

brake chopper. A regenerative resistor is connected exter

nally. This paves the way for optimal dimensioning and

also reduces the volume of the control cabinet.

Line filter

To optimize configuration from a cost perspective, line

filters are always connected in series outside the device.

Several power modules can thus be grouped for each line

filter resulting in reduced costs for the system as a whole.

Temperature-dependent fan control

The fan is controlled relative to the temperature inside

the device. This leads to a reduction in energy consump

tion and therefore lowers the overall costs of a system.

DC link coupling

DC link coupling can be achieved for a number of power

modules for the purpose of energy compensation. Surplus

energy is not “burned”. It is made available to other drive

units without taking additional energy from the supply

network.

Safety module

With the optional safety module, the option “safety stop”

in accordance with EN ISO 13849 safety category 4 can

easily be realized without the integration of additional

contactors in the motor line. This ensures that the struc

ture of the safety circuit remains simple and transparent.

The danger potential of the machine is reduced — the

machine works reliably.

b maXX 4400 offers a performance range from

1.1 kW to 315 kW. All devices have integrated

rectifiers, DC link capacitors and inverters.
