field designates the position of the thruster (part of the welder surrounded by sheet metal covers) relative to the column as indicated by the scale affixed to the right side of the column and a white line printed on the rear of the welder. Once these settings are entered, pressing the DONE button causes a return to the main UTILITIES screen, where a yellow SAVE OTHER SETTINGS button appears. Press this button, then Save and DONE on the following screen to retain the settings in memory.

The EXPORT LAST WELD GRAPH DATA button is used to send weld profile data information for the last cycle to an externally connected computer via the Dual Servo Spin Welder Utility (refer to Chapter 8). This data includes the spin torque, spin orientation, vertical thrust, vertical position, and vertical speed. It is displayed in graphical format in the Utility and can be exported to an ASCII file.

SYSTEM SETUP Tab

The third tab is labeled SYSTEM SETUP and is shown in Figure 5-32.

The welder contains an assembly used to limit the downward travel of the press to prevent tooling from coming in contact. This assembly consists of a mechanical stop block with an integral proximity switch, whose position is adjusted via an elevator screw driven by a small DC motor. If, during normal operation, the press travels down and the proximity switch becomes active, the press motion will quickly decelerate to a stop. The actual physical hard stop is approximately 4 mm below this position since the stop block includes a cushion to protect the vertical servo actuator from damaging impact loads. To set the lower limit proximity switch position, first press the VERTICAL TRAVEL LOWER LIMIT button. Then press the Initialize button shown on the screen in Figure 5-33, which will cause the stop block to move all the way down, which takes 1 minute as indicated by a flashing message. When this step is completed, the screen will change as indicated in Figure 5-34. Next, jog the head down to the desired travel limit position (at least 4 mm
