SECTION 1 AX1500 Quick Start This section will give you the basic information needed to quickly install, setup and run your AX1500 controller in a minimal configuration. Important Safety Warnings The AX1500 is a high power electronics device. Serious damage, including fire, may occur to the unit, motors, wiring and batteries as a result of its misuse. Transistors may explode and require the use of safety glasses when operated in direct view.
AX1500 Quick Start Locating the Connectors Take a moment to familiarize yourself with the controller’s connectors. The front side (shown in Figure 1) contains the Power/Status LED and the 15-pin connector to the R/C or microcomputer, as well as connections to optional switches and sensors. Note: The Status LED is not used in version 1.7b of the controller’s software. Connector to Receiver/Controls and sensors Power LED Status LED FIGURE 1.
Connecting to the Batteries and Motors Connecting to the Batteries and Motors Connection to the batteries and motors is shown in the figure below and is done by connecting to the controller’s terminal strip. Motor2 Motor Cables + Battery Power Cables Fuse - Motor1 Optional Power on/off switch + Power Control Wire 12V to 40V Motor Battery Controller Notes: - The Battery Power connection are doubled in order to provide the maximum current to the controller.
AX1500 Quick Start The controller includes large capacitors. When connecting the Motor Power Cables, a spark will be generated at the connection point. This is a normal occurrence and should be expected. Using the Power Control Terminal The AX1500 includes a DC/DC converter that will generate a 12V internal supply from the main +12 to +40V battery. As a result, the controller will turn On as soon as the Vmot and Ground terminals are connected to the battery.

Obtaining the Controller’s Software Revision Number FIGURE 5. Roborun Utility screen layout To connect the controller to your PC, use the provided cable. Connect the 15-pin connector to the controller. Connect the 9-pin connector to your PC’s available port (typically COM1). Apply power to the controller to turn it on. Load your CD or download the latest revision of Roborun software from www.Roboteq.com, install it on your PC and launch the program.
AX1500 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.
