the drives first, but at the control level.
With the expansion of the controller
software to include the Safety Controller
c250-S a complete automation solution
is provided for safety engineering and
control and drive tasks. Topped with the
safety I/O module, all the safety aspects
in the machine module can be evaluated.
EtherCAT is used for data transfer.
Features
• Compact Controller c250-S for easy
mounting using the DIN rail
• Directly stackable safety I/O module
with integrated connection without
extra wiring
• Plug-in connections of the safety I/O
module for quick set-up
• Portfolio expansion means reduction in
machine components
• High-quality solution thanks to

The machine module solution can really look that easy.
Simply expanding the modular system
• FAST machine module solutions are achieved these
days with a controller and the corresponding servo
drives. This solution is now topped with integration
of the safety controller. Using the same network via
EtherCAT, the system topography is the same.
• The safety controller can be parameterised via the
PLC Designer engineering tool, in parallel with the
controller 3200 C and the servo inverter.

From drive-based safety to controller-based safety:
this new simplicity can be seen among other things
in the noticeably reduced amount of wiring. This is
the result of directly interlinking the Lenze controllers
for safety and motion – in addition to ready-made
software solutions from the FAST Application
Software Toolbox. Hence in practice, a FAST module
can, for instance, control the reduction in traversing
speed while at the same time the safety controller
within the system can monitor the safe maximum
speed.
