SPEED CONTROL OF DC MOTOR USING PULSE WIDTH …
rcciit.org.inThe speed control of DC motor is important in applications where precision and protection are of essence. Purpose of a motor speed controller is to take a signal representing the required speed and to drive a motor at that speed. In this project controller presented uses the pulse width modulation (PWM) technique for speed control of DC motor.

PWM Spindle Control using Mach3 - dave.ogormanfamily.com
dave.ogormanfamily.comConsideration of Pulse Width Modulation (PWM) control only is covered. It does not cover Step and Direction or simple Relay control of spindle motors. 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. The settings for the VFD refer to a

A “0” is represented by a pulse distance of 1.125 ms and a “1” by a pulse distance of 2.25 ms. 8 address bits are used to identify the device to be controlled. A further 8 bits are used for the transmission of the command data. As mentioned above, the words are
