Whether compact, high-end or customised embedded controller, the scalable and flexible controllers from Eckelmann’s E°EXC controller family are the ideal basis for the robust and efficient automation of machines and plants.

Flexible controllers - providing simple to complex automation solutions

The E°EXC controller is the all-purpose hardware basis for PLC, motion control and CNC solutions. It supports numerous technology-specific functions and permits the development of sophisticated applications.

Processor performance, interfaces, memory and programming can be selected so as to meet the needs of each individual application. The controllers are available in the following classes:

Control technology with technological know-how

Extensive function libraries as well as the consistent use of standards for interfaces and programming make for flexible and lean engineering. The CNC offers a wide range of technology functions, from non-cylindrical grinding to flame cutting. CNC solutions from Eckelmann are used in a variety of applications such as turning, milling, drilling, grinding, bending, punching, sawing, etc. The extensive motion function library in accordance with PLCopen® is capable of controlling even sophisticated multi-axis systems with high demands in terms of synchronicity and precision, e.g. in printing machines or handling systems for solar wafers. And with CODESYS mechanical engineers may enjoy all the benefits of the object-oriented programming of PLC-applications in accordance with IEC 61131-3.

We offer solutions, not components! Therefore, our customers always have a direct connection to our application and development engineers who help them solve tricky tasks on the basis of extensive experience and modern development methods such as HiL simulations for special kinematics or complex path controllers. Due to customised adaptations, Eckelmann’s control technology can be adapted to almost any deployment scenario.

E°EXC 88: High-end controller for CNC, PLC and motion

E°EXC 88 high-end controller
E°EXC 88 high-end controller

E°EXC 88 is a compact DIN rail controller that excels by the comprehensive instruction repertoire of the CNC core and the seamless integration of CNC and motion functionalities in controlling.

  • 64 motion axes to PLCopen with extensive motion function library
  • 32 CNC axes with comprehensive instruction repertoire
  • Possibility of seamless combination of motion with CNC functions
  • Extremely fast, robust and easy-to-wire real-time I/O system E°XBM

Due to the seamless integration of CNC and motion functionalities to PLCopen, it is possible to operate additional handling axes next to the CNC and to select the optimal task-dependent technology, i.e. CNC or motion, or a combination of both. The CNC processing of a moving workpiece is also possible.

The E°EXC 66 is the standard controller for CNC, PLC and motion control applications in the high-performance level. A RISC processor provides pooled computing power.

Integrated ethernet-based real-time communication between controllers, drives and I/O peripherals: the E°EXC 66 / H43 with sercos III interface provides modern communication solutions for all applications of industrial automation—open, manufacturer-independent and IEC-compliant.

The E°EXC 66 COMPACT is a space-saving controller, whose optimised scope of functions and interfaces offers a particularly favourable price-to-performance ratio. Its areas of application are small and medium-sized PLC applications. Compared to the full version, the compact controller has fewer interfaces and is only available as PLC. But in return it comes with its own power supply, providing also the expansion modules with power.
