PTmotion.cs

PT Simple Motion sample application.

This application demonstrates how to use PT Motion.

Precondition

This sample code presumes that the user has set the tuning paramters(PID, PIV, etc.) prior to running this program so that the motor can rotate in a stable manner.

Warning

This is a sample program to assist in the integration of your motion controller with your application. It may not contain all of the logic and safety features that your application requires.
