Standard Features on XM Weld Process Controller
The Emergency Stop (E-Stop) button immediately aborts the weld program, stops weld current output from the power supply, and ceases all servo-controlled motion. The shield gas will remain flowing until the end of the Post Weld segment to prevent oxidization of the weld piece. The system remains inactive until an operator pulls out the Emergency Stop button and pushes the Clear E-Stop soft button.
Each soft button has a corresponding label or grey area (indicating an inactive button) on the LCD screen. Based on the selected Mode (Weld, Edit, or Set Up) and the screen within that mode, the function of the soft buttons will change. Details are explained in each corresponding section.
The Mode buttons (Weld, Edit, and Set Up) put the controller into its corresponding mode of operation. Controller and module preferences and settings are addressed in the Set Up Mode while weld programs (or schedules) are built in the Edit Mode, then executed in Weld Mode.
The Sequence buttons (Start, Stop, and Advance) are used with the weld program. The Start button activates the current weld program. The Stop button terminates any running process or operation. If depressed during a weld program, the Stop button will advance the current weld segment to the down slope segment. If the program is already in the down slope, pressing the Stop button will terminate the program. The Next (or Advance) button’s function depends on the weld program settings and can be depressed to progress to the next programmed event. The Advance button illuminates when it can be used to advance a sequence in the program.
The Joystick Controls command movement of their assigned axes. The joystick control has a proportional feature, meaning, the farther the physical joystick is moved along its throw, the faster the axis it commands will travel. Each Joystick is divided into two axes of motion: a vertical axis and a horizontal axis with corresponding labels. Each axis has programmable parameters (Command, High Speed, and Low Speed) and can be assigned to any axis.
The Function buttons are quick access buttons to move positioners or axes, enable or disable process-specific functions, and control gasses. These buttons are divided into four sections: Disable, Gas, Motion, and Jog.
Two USB ports are included to facilitate file transfers to and from external sources. Files can be added to or deleted from a USB memory device directly from the XM Controller. The USB connections are located under covers behind the front panel.
The Soft Programming Knobs (or simply soft knobs) override weld program parameters in Weld mode. In Edit and Set Up Mode, the knobs navigate through the screen and adjust the settings. By rotating a knob clockwise or counter-clockwise, the operator can scroll through the display to reach a desired item and then increase or decrease a value. Each knob also acts as a push button by pressing down on the knob, which allows the operator to select different parameters depending on the current mode.
The LCD Display presents the graphical interface screens on the 6.4” TFT screen. The Weld, Edit, and Set Up Modes and their program screens are presented on the display for data entry or manipulation.
