| 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
