| Baumüller is setting standards with
b maXX, its newest generation of drives. This series of converters
and controllers was developed to meet current and future automation
technology requirements worldwide.
|
b maXX has up to 11 drawers
for plug-in modules and can therefore be individually
adapted for special automation tasks. Special plug-in
modules interface b maXX, including interface adaptors
for most standard bus systems. The plug-in b maXX-drivePLC
module provides integrated intelligent control.
b maXX serves as a basis for both simple and complex
automation solutions.
The requirements placed on machines and systems center
on the ability to cope with future needs, flexible expansion
capacity and simple adaptation with modified production
processes. |
With b maXX, Baumüller provides the drive and automation
solution that meets the following requirements:
 |
Modular
b maXX can be adapted in line with the specific requirements
of a given application. The modular design guarantees
that the drive system can be expanded adequately. Plug-in
modules equip the controller, for example, with control
functions or additional field bus interfaces. This ensures
that the user can benefit from cost-effective configuration
since only the capabilities and computing power required
for a specific job need to be purchased. |
 |
Scalable
The drive capabilities are expandable to meet the
demands and requirements that are placed on a machine
or system. The performance capability of b maXX extends
from the simple to the highly sophisticated automation
application. Functionality and computing power are selected
relative to the application on the basis of a consistent
hardware and software platform.
|
 |
Open
b maXX offers access to automation bus systems. The
field busses EtherCAT, CANopen, CANsync, PROFIBUS-DP
and Sercos are fully supported. An OPC server is provided
for the interfacing of visualization systems. Remote
access to process variables within the drive PLC is
also possible without additional programming.
This is accomplished through the use of the OPC server
and Ethernet TCP/IP connection available along with
the b maXX-drivePLC. The b maXX-drivePLC module makes
the controller intelligent and hence perfectly suitable
for all special automation requirements. Thanks to the
standardized programming language IEC 61131, control
programs and technology functions can also easily be
created by the user. |
User benefits
The b maXX guarantees user-friendly operation, simple
commissioning and maintenance as well as optimized configuration
with maximum flexibility for integration into a wide
variety of machine concepts. This qualifies it as a
highly cost-effective and technically optimal solution.
Engineering activities are reduced to a minimum. The
stocking and storage of replacement parts is optimized
due to the pluggable modularity.

b maXX 4400 - modular servo controller - flexible
and expandable
The b maXX 4400 is equally suitable for simple speed control
applications or highly synchronous, multi-axis applications
as it can easily be equipped with:
 |
- analog I/Os
- digital I/Os
- encoder emulation (incremental / SSI)
- parameter storage module
- encoder evaluation (for closed loop applications)
- field bus interfaces
- integrated PLC: b maXX-drivePLC
The hardware can therefore be adapted in line with
the exact requirements of your automation solution.
Drive controller
b maXX 4400 uses the principle of vector control for
maximum dynamic response. Position control, speed control
and current control are integrated and have a cycle
time of 125 µs. As a result, the motor is powered
in a fast and precise manner. Clock speed and production
output can be increased effectively. The operating modes
jogging (teaching), referencing and synchronous operation
with electronic gears are also supported.
All the drive parameters can be permanently saved
in a maximum of 8 data records. They can also be switched
over and defined online. The data records are switched
over via the digital I/Os, the field bus interface or
the b maXX-drivePLC. As a result, b maXX can quickly
and easily be adapted in line with variations in the
production process. This significantly reduces retrofitting
times and enhances the flexibility of the production
process.

Integrated positioning control
Integrated positioning control paves the way for relative
or absolute positioning. Positioning can be trapezoidal with
acceleration and brake ramp or in the form of an “S“
curve. Jolt-free motion sequences extend the life of the mechanical
components and enhance the availability of the machine. The
amount of maintenance required is also reduced.
16 positioning profiles can be stored. These can be switched
over online via the digital I/Os or the field bus interface.
Hence, the user does not require a PLC for simple motion sequences.
More demanding motion control with complex motion sequences
and logic operations are implemented by the b maXX-drivePLC.
This relieves the burden on the machine‘s control
unit or, if required, a smaller control unit can be used and
the highly dynamic motion sequences can be executed by the
b maXX-drivePLC. Elaborate bus systems from the control unit
to each of the drives are no longer necessary as the b maXX-drivePLC
is already located in the drive where it directly executes
the high-performance tasks. Depending on the application,
the b maXX-drivePLC can control a single machine module or
the entire machine.

Fields of application
b maXX 4400 was designed and developed for a wide
range of applications including very simple applications
with open loop vector control for the encoderless control
of standard motors. For standard servo applications
with closed loop vector control b maXX 4400 is typically
equipped with:
- encoder feedback such as resolver, SinCos or incremental
- digital I/Os for recording control signals
|
This configuration meets the requirements for simple positioning
and drive tasks in the following fields: conveyor belts, material
handling systems, cutting equipment, punches, presses and
many more.
For complex automation tasks b maXX 4400 is typically
equipped with:
- encoder feedback such as SinCos or incremental
- asynchronous field bus interfaces such as CANopen or Profibus
DP
- synchronous field bus interfaces such as CANsync or Sercos,
CANopen with Sync-Telegram
- EtherCAT
- Ethernet TCP/IP: the data networks for diagnosis, visualization,
teleservice, engineering
- integrated PLC: b maXX-drivePLC for complex control /
technology tasks
- digital I/Os for process interfacing
- analog I/Os for measured data acquisition
- encoder emulation (incremental / SSI)
