1.1 Introduction to the H3U Series PLC
The H3U series PLC is a third-generation high-performance PLC developed by Inovance. Thanks to the latest
industrial-strength CPU and FPGA hardware structure and embedded software with independent intelligent
property rights, the product performance and capacity has been substantially improved. In addition, it provides a
wide range of functions including positioning, trajectory tacking control, and network communication. The series
consists of the H3U standard model and the H3U-PM motion control model.
Main performance specications of the H3U standard model and the H3U-PM motion control model are introduced
