Miscellaneous Application Notes
There are a number of Application Notes that have been created by the Control Techniques USA Technical Support team. Too often, application solutions are dealt with externally ( at additional system cost ). These application notes offer some insight into solutions for many common Drive applications by exploiting many of the inherent internal ( unknown or mysterious ) functions within Control Techniques Drives at no additional cost.

The Application Notes tend to be educational in nature, so reading them even if you do not have an immediate application need, tends to give one a better overall understanding of the inner workings and facilities within our Drives that are available to help solve an application.

Many of the Application Notes utilize our software tools. One can tend to learn these tools by simple observation and thru examples within our Application Notes. We would advise you to download and save the APPLICATION NOTE DIRECTORY within your PC as it contains active web links that can be clicked to download any of the Application Notes directly.
