Codesys-based motion controller eases programming

27 May, 2021

The Taiwanese automation supplier Delta has announced a series of compact, mid-range motion controllers based on the Codesys development environment. The AX-308E controllers, which can handle up to eight EtherCat servodrives, as well as inverters, remote I/O modules and third-party devices, are said to reduce programming times.

News of the motion controllers follows Delta’s recent announcement of a Codesys-based multi-core industrial PC (the AX-8) which can control up to 64 motion axes via an EtherCat interface. The AX-8 allows PLC, motion control and Windows OS functions to run simultaneously without affecting each other.

“The Delta AX-308E is designed for motion control applications in markets as diverse as assembly, packaging, and woodworking,” says Simone Orlandi, product manager in Delta’s Industrial Automation Business for the EMEA region. “Together with the AX-8 series, we increase the scalability of the Delta motion control product portfolio, offering customers with more options."

The controller is compatible with Delta’s existing AS PLCs and supports a broad range of industrial communication protocols including EtherCat. It supports additional I/Os, temperature sensing, and load cells via AS expansion modules. The minimum EtherCat synchronisation time for eight axes is 2ms, and the minimum execution time for basic instruction is 5ns.

The AX-308E can control up to four pulse-train drives using fast digital outputs. Its interfaces include Modbus TCP/RTU, Ethernet/IP, and OPC UA. There are 16 digital inputs, eight digital outputs, two serial ports, two incremental encoder interfaces, and an SSI port.

Delta’s DIAStudio software platform offers support from the planning stage through to execution and commissioning, easing the implementation of both simple and complex motion control, including single- and multi-axis movements, gearing, electronic cams and interpolation. It complies with the IEC 61131-3 and PLCopen standards. Built-in tools include an oscilloscope, simulator and cam design editor.
