V7 Drive Textile Fiber Winder Software Manual

This document describes custom software for Yaskawa V7 drives used in textile fiber winding applications, specifically for controlling spindle and traverse motor speed ratios to prevent ribbon defects. It details the winder ratio reference feature, which uses Memobus broadcast commands and adjustable numerator/denominator parameters to electronically maintain precise speed ratios, supporting precision winding, random winding, and pattern jump (ribbon breaking) methods.
