Delta Launches the AX-308E, its First CODESYS-Based AS Series-Compatible Motion Controller

Delta, a global leader in power and thermal management solutions and industrial automation systems, has introduced the AX-308E as the first of its compact, mid-range AX-3 Series PLC motion controllers. It is based on CODESYS, the development environment complying with international standards, targeting intelligent industrial automation applications. Thus, it shortens the time of learning and programming. This multi-axis motion controller, which controls up to eight EtherCAT servo drives, is compatible with the existing AS Series and supports a broad range of industrial communication protocols, including EtherCAT and offers a complete motion control solution.

“The Delta AX-308E is designed for motion control applications in markets as diverse as assembly, packaging, and woodworking,” said Simone Orlandi, product manager, Industrial Automation Business Group for Delta in Europe Middle East & Africa (EMEA). “Together with the AX-8 series, we increase the scalability of the Delta motion control product portfolio, offering customers with more options.”

Variable interfaces make it flexible

The AX-308E is able to control up to eight EtherCAT servo drives, as well as inverters, remote I/O modules, and other third-party devices. Furthermore, up to four pulse-train drives can be controlled using the integrated fast digital outputs.

The broad array of connectivity interfaces offered, including Modbus TCP/RTU, Ethernet/IP, and OPC UA, make this PLC ideal for Industry 4.0. Complementing these communication capabilities are 16 digital inputs, 8 digital outputs, two serial ports, two incremental encoder interfaces, and an SSI port. Support for additional I/Os, temperature sensing, and load cells is ensured thanks to compatibility with Delta’s existing AS Series Expansion Module.

Faster time-to-market with DIADesigner-AX

DIADesigner-AX is the integration of CODESYS in DIAStudio software platform. The environment provides support from the planning stage through execution and commissioning, easing the implementation of both simple and complex motion control, including single- and multi-axis movements, gearing, ECAMs and interpolation, in accordance with international standards, namely IEC 61131-3 and PLCopen. Software developers can also benefit from the other integrated tools, such as oscilloscope, simulator and CAM design editor.
