Well suited to a harsh environment – the AC 800PEC for traction
Traction with its particularly harsh environmental conditions
is one of the most important applications of the AC 800PEC.
The controller operates through a wide temperature range
(– 40 to + 70 °C), with vibrations according to traction
standards. The compact solution is the ideal response to
the demands of restricted spaces and allows integration of
the processing unit together with all the I/Os in the same
compact hardware device.
Top reliability is a must – the AC 800PEC in power generation
Typically, excitation systems are used for generator control in
power-plants where high reliability is the No. 1 requirement.
Due to the very short process cycles, traditional redundancy
concepts are no longer applicable.
The modular architecture of the AC 800PEC not only greatly
reduces the complexity of the overall system, but thanks to
redundant subsystems also provides increased reliability. In
the case of a problem in one subsystem, the main controller
switches over to the remaining subsystems, which are scaled
in such a way that the overall task can still be fulfilled. Should
the main controller fail, a second controller is available in hot-standby.
Precision for optimum quality – the AC 800PEC for industrial processes
The most demanding function in a rolling mill is thickness
control. By using the powerful AC 800PEC controller and its
ability to implement C-Code beside the standard IEC 61131-3
program level, a new thickness control solution for cold
rolling mills has been developed based on an MIMO (Multi
Input Multi-Output) control concept. The benefit to the
customer is an improvement in thickness deviation by up to 50 percent.
