The settings for the VFD refer to a Danfoss FC51 VLT Micro Drive. It also assumes that a Variable Frequency Drive (VFD) is going to be used to control a synchronous 3 phase AC Motor for the spindle motor. It does not cover Step and Direction or simple Relay control of spindle motors. Consideration of Pulse Width Modulation (PWM) control only is covered. Hopefully this dissertation will make it easier for others. I wanted to pass on to others the experience I gained when I designed and manufactured my cnc lathe. Created By Chris Humphris Revision A PWM Spindle Control using Mach3 Introduction This document outlines my method of controlling spindle speed on various machines. ![]()
