The INVT AMC4300 motion controller hardware manual provides an overview, specifications, control modes, interface definitions, and driver wiring instructions.
The AMC4300 is a motion‑control platform that uses a Cortex‑A8 processor, a real‑time Linux OS and FPGA hardware to control up to 4, 8, or 16/32 axes via EtherCAT, RS‑232/485/422, USB and other interfaces. It supports standalone (Alone) operation with a VGA display as well as A+PC networking modes, and includes built‑in PID/FF control for precise motion.
The manual details the controller's hardware resources, connector pinouts, GPIO and ARIO boards, and provides wiring diagrams and parameter settings for a wide range of servo drives from INVT, Delta, Yaskawa and other manufacturers. An appendix describes system firmware updates and SD‑card replacement procedures. This manual is written in Chinese.
