b maXX 4600/4700 — 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

Peak and nominal load devices available in five sizes

supplement the proven b maXX series. Regardless of

whether you require maximum performance on a

continuous or temporary basis — the b maXX series

offers customised drive solutions for every application.

The tried-and-tested b maXX automation and

drive solution is being expanded to include new

peak and nominal load devices from the 4600 and

4700 series. Baumüller is now able to meet the

specific require-ments of applications in the injec

tion moulding or extrusion sector, for example,

where either short-term peak output or permanent

high performance is required. As a result, the drive

can be adapted perfectly to the power requirements

of the relevant application.

Although the devices in the series are more power

ful, they have a compact design and take up much

less space in the control cabinet — double benefits

for the user.

It is often the case with electrical drives that energy costs

make up almost 90% of the overall life-cycle costs. With

this in mind, regenerative systems help to reduce the total

cost of ownership.

Baumüller’s tried-and-tested b maXX automation

and drive solution is being expanded with the

addition of the new b maXX 4100 series regenerative

power supplies. These units work in conjunction

with b maXX 4400 series units, and can supply the

DC link voltage to one or more drives. By using a b

maXX 4100. all excess regenerative brake energy

generated by the system is returned to the AC

mains supply rather than wastefully dissipating

this energy as heat.

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.

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.
