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.

• Regenerative brake energy is returned as asine wave

• 3 frame sizes with 35 kW to 150 kW

• 60 second overload capability

• Current-controlled charging circuit

• Integrated control of charging and mains contactors

• Integral regenerative switching transistor

• Monitoring of mains, charging connection, mains

contactor, DC link voltage, and heat sink temperature

• Optional fieldbus modules

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.

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.

PLC and drive are synchronous

The in-drive PLC can have synchronized access to all setpoints and

actual values of the drive controller via the internal parallel bus.

Therefore, time-consuming communications programs do not

have to be created. The signal transit times are reduced to a mini

mum. This greatly enhances process security and also increases

the availability of the system.

All the advantages at a glance

• Fast, synchronous PLC access to the drive controller:

Sophisticated communications programs are no longer required 

— the burden on the system is relieved

• No wiring between the PLC and the drive:

Fault-prone cable connections can be reduced — availability is increased

• Compact design saves control cabinet space:

The volume of the control cabinet can be reduced

• Maximum PLC and servo controller performance due to independent

processors:

No limitations due to overlapping processes — the system remains stable

and reliable

• Baumüller is the contact partner for the PLC and drive system, and

therefore the automation system as a whole: Experience and competence

for the entire automation system — direct communication with one reliable

partner reduces the amount of engineering that is required

In-drive PLC

With a cycle time of 100 µs for 1.000 lines of STL, the

b maXX-drivePLC is suitable for both compre hensive control

and demanding motion control tasks. Through the use of our

drivePLC, the PLC can be assisted, down-sized or even

completely replaced. A new transparency and clarity is also

created in the application via the clean decoupling of motion

control applications from the machine program. The drivePLC

can be integrated into the b maXX 4400 servo controller series

and enables the uncomplicated creation of control technology

programs with ProMaster or PROPROG.

A CANopen master is included with the CAN option module for

b maXX-drivePLC. This enables up to 65.536 digital I/O points

to be switched. With the existing EtherCAT master challenging

and highly synchronized movement processes are controlled

directly on the b maXX-drivePLC. The extensive product range

includes decentralized analog and digital I/O modules.

The program memory of the b maXX-drivePLC is sufficient for

typical 120.000 lines of IL. 2 MB of RAM are available for variables.

The optional residual data memory of 100 KB is buffered battery-free

with a NVRAM. This means there is enough memory available for

sufficient code. Costly memory expansions can be dispensed with.

The battery-free NVRAM means that data is available maintenance

free and after every time the system is switched off and on without

any data loss.

• 32-bit Risc CPU 120 MHz

• 16 MB flash memory, of which

2 MB is reserved for the IEC program and 4 MB for cams

• 100 KB non-volatile RAM

Clever. Fast. Effective.

The b maXX-drivePLC module makes the drive in telligent. 

This in-drive control intelligence allows very fast access to

the setpoints and actual values of the drive controller.

Therefore, the functionalityof the drive can be enhanced

with complex motion, control and technology functions.

This ensures that the application can be created quickly

and economically.

Storage module

The parameter storage module contains all the parameters

that are set on the drive controller of the b maXX for all 8

parameter data records and all 16 positioning profiles.

New parameters can be loaded to the drive controller

simply by plugging in the module.

Given that the parameter module is pluggable, a drive can

be replaced during servicing without the need for any

knowledge of the operating software.

Servicing could not be easier.

Function and option modules for b maXX 4400

With more than 30 different function and option

modules b maXX can easily be adapted in line with

the individual tasks of the automation and drive

solution.

The individual modules are designed as plug-in

boards and therefore the drive controller no longer

has to be ordered as a preassembled unit. By using

various plug-in boards, the machine manufacturer

can secure a wide variety of functions and configure

the appropriate combinations on their own. In this

way, he can react quickly and flexibly to new

requirements.

This system also ensures that the drive can be

quickly expanded at the user‘s facility. Production

adjustments can be implemented within a short

space of time and with minimal effort.

The established automation and drive solution

b maXX was expanded with the new peak load and

nominal load devices of the 5600 and 5700 series.

The units complete the b maXX series and are

available in five sizes. Therewith, Baumüller meets

the requirements of industry-specific applications

such as in the field of injection moulding or extru

sion processes, because here either short-term

peak power or permanent maximum power in

constant operation are in demand. The drive can

optimally be matched to the power demands of

the respective application.

Even though the series is equipped with greater

power rating it is available in smaller sizes and mini-

mizes the required space in the control cabinet –

hence the user benefits twice.

b maXX 5600/5700 — Your benefits at a glance

• Optimized drive solution for specific industry requirements

• Different sizes available for compatible drive dimensions

• Less space required in the control cabinet due to smaller

devices and the use of

water cooling, control cabinet therefore less expensive to

manufacture

• Water cooling in the control cabinet provides a cost-effective

solution

• Compatible with other devices in the b maXX series

Baumüller sets standards with the servo controller

generation b maXX 5000. The further development

of the successful b maXX series towards modular

systems convinces with high-performance power

units in air-cooled, water-cooled and cold plate

cooling versions and with flexible expandability

and the accessibility to an integrated communica

tion concept. Standardized as well as complex

automation solutions can be implemented with

Baumüller’s converters and controllers within a

power range between 1 and 215 kW.

The machine and installation requirements with

regard to future reliability, flexible expansion

possibilities and a simple adjustment to changed

production processes were already considered

during the preliminary development process stages

of the b maXX 5000.

Individual modules easily can be removed or

added over an integrated drive connect system

without having to disconnect the entire drive

system.
