| With a typical cycle
time of 100 microseconds for 1,000 lines of STL,
b maXX-drivePLC is one of the fastest in-drive
PLCs in the world.
 |
The b maXX-drivePLC
module makes the drive intelligent. This
in-drive control intelligence allows very
fast access to the setpoints and actual
values of the drive controller. Hence, the
functionality of the drive can be enhanced
with complex motion, control and technology
functions. This ensures that the application
can be created quickly and economically
The CAN option module serves as a CANopen
master for b maXX-drivePLC. Up to 65,536
digital I/O points can be connected with
this module. With the existing EtherCAT
master and the CANsync master, sophisticated
and highly synchronous motion sequences
can be controlled directly on the b maXX-drivePLC.
The comprehensive product range includes
decentralized analog and digital I/O modules.

The program
memory of the b maXX-drivePLC
is sufficient for 120,000 lines of STL.
2 MB RAM is available for variables. The
optional, nonvolatile 56 kb memory requires
no battery and features a NOVRAM buffer.
This guarantees that sufficient code memory
is available. Cost-intensive memory
expansions are not necessary.
Thanks to the battery-free NOVRAM, the
data is available maintenance-free and without
data loss after each switching off/on operation.

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 parallel bus. Hence, time-consuming
communications programs do not have to be created.
The signal transit times are reduced to a minimum.
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.
