AX500 Quick Start

Each software version is identified with a unique number. Obtaining this number can be done using the PC connection discussed previously.

Now that you know your controller’s software version number, you will be able to see if a new version is available for download and installation from Roboteq’s web site and which features have been added or improved.

Installing new software is a simple and secure procedure, fully described in “Updating the

Controller’s Software” on page 146 of the User’s Manual.

Exploring further

By following this quick-start section, you should have managed to get your controller to operate in its basic modes within minutes of unpacking.

Each of the features mentioned thus far has numerous options which are discussed further in the complete User’s Manual, including:

•Self test mode

•Emergency stop condition

•Using Inputs/Outputs

•Current limiting

•Closed Loop Operation

•Software updating

•and much more
