Dual Servo Spin Welder User’s Manual
Starting A Weld Cycle
All weld cycles must be initiated from the RUN screen after the machine is initialized and with the press at the top-of-stroke position. If not already on this screen, press the RUN button first (see Figure 5-2). If you had powered down the welder or pressed the Abort button, the screen may instruct you to press the RESET FAULT button and then reset the machine by activating the RUN switches. After the reset process is completed, the welder is ready to run a cycle, which is indicated by the smiley face in the upper left corner of the screen. If a frowning face appears instead, it signifies that the welder is not ready for one of several reasons (for example, the part presence sensor is not activated if the Part Present option is enabled).
To run a cycle, press both RUN switches simultaneously. The press will begin to descend and spin motor will accelerate. Both servos will reach their programmed weld speeds by the time the press reaches the trigger position (defined in SETUP > PRE-TRIGGERtab > TRIGGER Position). The Trigger Indicator (see Figure 4-1) will turn on when the weld starts, which occurs at the Trigger position if the Torque Trigger Option is disabled, or when the trigger torque is sensed if the Torque Trigger Option is enabled. The weld phase continues until the selected welding parameter (time, number of rotations, vertical distance, or energy) has been reached, at which point the Trigger Indicator turns off. The spin motor then stops and the welder begins the hold phase, during which the press moves according to the settings defined in the Hold Setup menu. To complete the cycle, the press retracts to the top-of-stroke position and the RUN screen is populated with weld process data results. The base switches must remain actuated until the start of the hold phase; otherwise, the cycle will be aborted and no weld data will be displayed.
If a weld cycle completes successfully, the smiley face appears to indicate that the machine is ready to run another cycle. If a cycle terminates abnormally, a fault message will be displayed on the screen describing the error condition. The fault must be cleared and the welder reset before another cycle can be initiated.
