The WinWAM software can operate all WAM test machines, including WAMhs and WAMsc2. WinWAM is a menu-driven package designed for operator interface with tribological parameters for control, monitoring and data acquisition. From the main screen the operator can utilize a test setup screen, machine setup screen, temperature control screen, load display screen, PMAC controller screen, calibration screen, log data screen, run script screen and data capture screen. The WinWAM software is completely documented in a reference manual. The software has proven to be a good tool for new operators and a valuable asset for a highly flexible tribology testing environment. WinWAM software is supplied with the purchase of all WAM test machines.

WinWAM software allows the user of WAM machines to control the machine functions and collect and display data. The software allows WAM machines to perform traction tests with input of parameters, such as entraining velocity and percent slip. The test parameters are converted into the required motor speed, applied forces, and positional data that the machine requires. The resulting velocities and forces are measured and converted back into tribological units, such as entraining velocity, sliding velocity and traction coefficient. Test parameters are plotted in real time and logged to a file. The performance of the WAM test system is constantly monitored, and the operator is notified in the event of a problem. The WinWAM user interface is based on the MS Windows operating system.  The machine interaction interface runs on a Delta-Tau Pmac2 motion controller. The Pmac2 system controls all speeds and positions, captures and filters the load and temperature data, and controls the heating/cooling outputs.

The WinWAM software provides several functional screens for easy operation (see figure). The Main Screen allows the user to enable various systems and to start a test. The center of the Main Screen displays a real time plot of selected variables. A Calibration Screen allows the user to adjust the calibration of all load cells, thermocouples and the clinometer. A Test Setup Screen includes a description of the test, test fluid, specimen identification and materials. The disc track diameter, ball or roller diameter and lube pump speed are also entered in the Test Setup Screen. A Machine Setup Screen allows the operator to control and monitor the position of the contact on the disc. The tilt angle of the ball or roller is also displayed. The specimen positions are shown both graphically and numerically. Pure rolling can be found by either manually positioning the X-axis and Y-axis, or by using a "PureRolling" button. The PureRolling button initiates a sequence of actions that finds pure rolling without operator intervention. Pure rolling is achieved when all horizontal X and Y forces are zero.
A Temperature Control Screen allows the user to input temperature set points, heating or cooling modes, heating power and cycle times. A Log Data Screen allows the user to select the variables that are written to a log file. The time period for logging is also selected. There is no limit to the number of variables that can be checked for logging. A Script File Screen is used for automating test protocols. While the script is running, the executing line is highlighted, and a status window shows the loop counts, ramp time and other parameters.
