BAUMULLER b maXX-drivePLC

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.

Speed up your applications

• Makes drives user-programmable

• Delivers excellent real-time performance

• Increases availability

• Reduces control cabinet size

• Ensures a consistently stable system

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

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
