AX-3 Series Motion CPU

The AX-3 Series Motion CPU adapts the CODESYS platform and supports both motion and logic control applications. It has multiple communication ports and an EtherCAT motion control interface onboard. It also offers motion control function blocks complying with international standards and supports up to 8 real axes. The AX-3 Series Motion CPUs are widely applied in diverse automated equipment used in the woodworking, packaging, printing, labeling, textile, and pharmaceutical industries.

Product Introduction

Features & Benefits


  • 8 axes EtherCAT motion controller with min. 2 ms synchronization time
  • Adapts the IEC 61131 compliant CODESYS software platform for equipment automation integration
  • Supports AS Series PLC I/O modules and allows flexible scalability
  • Built-in Ethernet (* 2) / RS-485 / RS-232 encoder interfaces to connect various devices at the same time
  • Integrated software platform provides a standardized programming and controller development environment, offering various tools for motion control including PLCopen MC function block, E-CAM editor, positioning planning chart, and many more
