V7 Drive Textile Fiber Winder Software Manual

This document describes custom software for Yaskawa V7 low horsepower drives (0.4–3.7 kW) used in textile fiber winding applications. It details a winder ratio reference function that uses Memobus broadcast commands and configurable numerator/denominator parameters to precisely control spindle and traverse motor speed ratios, enabling pattern jump (ribbon breaking) winding for high-speed, high-quality package production.
