CELL SETUP SCREEN


CELL SETUP SCREEN

The cell is the area in which spot welding is performed. The robot, controller, equipment, and cell controller are some of the kinds of equipment included in a cell. You must establish the interface between the robot and cell controller before you can run production operation. Cell interface setup provides a method to define cell information to suit your installation and requirements. The CELL SETUP screen provides items you can set as they apply to your installation.

Table 1.  Cell Interface Setup Items

ITEM DESCRIPTION

Home I/O macro name

default: HOME_IO

This item specifies the name of the teach pendant program SpotTool+ executes whenever the robot returns to home, and is not executing a program started via the SOP Start, or Production Start method. The teach pendant program HOME_IO.TP is supplied with SpotTool+. This program is a template program. You must edit the program and insert the appropriate I/O assignments.

Shell polling

This item enables and disables shell polling. Shell polling is the periodic scan of critical process inputs that SpotTool+ monitors constantly whenever a program is not running. If your I/O is not fully configured, you might choose to disable shell polling temporarily to avoid error messages. Shell polling monitors the following items:

For IWC,

  • Iso Contactor

  • Major Alarm

  • Minor Alarm

  • Weld Enable Mismatch

  • Water Flow

  • Water Saver

  • Transformer OK

For Stud Welding

  • Air Pressure Low

  • Stud Feeder Low

  • Maintenance Input

  • Weld Enable Mismatch

  • Minor Alarm

For SpotWelding

  • Iso Contactor

  • Water Flow OK

  • Water Saver OK

  • X-former OK

  • Major Alarm

  • Minor Alarm

  • Weld Enable Mismatch (Enabled Weld Output does not match Weld Enabled Input)

Production Prompt Boxes - The following two items allow you to set whether to display specific prompt boxes when a production start signal has been received.

NOWELD

default: ENABLED

This item specifies whether to display a prompt box indicating that a NOWELD condition exists when a production start signal has been received. ENABLED indicates that the prompt box will be displayed if the condition is true.

NOSTROKE

default: ENABLED

This item specifies whether to display a prompt box indicating that a NOSTROKE condition exists when a production start signal has been received. ENABLED indicates that the prompt box will be displayed if the condition is true.

Production run speed

default: 0

min: 0

max: 100

 This item allows you to specify the general override value (displayed in the upper right hand corner of the teach pendant screen) SpotTool+ should use automatically when a production start signal is received. SpotTool+ will display a prompt box (if speed override < 100 is ENABLED) and then run the production program at the specified override value. A value of zero indicates that the current general override value will be used.

If the Default Dispense option has been loaded then this item appears on the menu but is not directly editable. The value may be set directly via the system variable: $atcellsetup.$prodrun_spd.

If the Default Dispense option has been loaded then the functionality for this item changes as well. For more information refer to the flow chart figure titled "Production Run Speed functionality if the Default Dispense option is loaded" in the SpotTool+ Setup and Operations Manual. Note that regardless of if the Default Dispense option has been loaded the Wet/Dry Mode cell input is checked again after this process in order to set the controller wet / dry mode.

Production resume speed

default: 0

min: 0

max: 100

This item allows you to specify the general override value (displayed in the upper right hand corner of the teach pendant screen) SpotTool+ should use automatically when a production start signal is received to resume a paused style. SpotTool+ will display a prompt box (if speed override < 100 is ENABLED) and then resume the style at the specified override value. A value of zero indicates that the current general override value will be used.

If the Default Dispense option has been loaded then this item appears on the menu but is not directly editable. The value may be set directly via the system variable: $atcellsetup.$prodrsm_spd.

If the Default Dispense option has been loaded then the functionality for this item changes as well. For more information refer to the flow chart figure titled "Production Resume Speed functionality if the Default Dispense option is loaded" in the SpotTool+ Setup and Operations Manual. Note there that the default value of $SLCELLSU[1].SPX_INT8 is 0 - therefore bit #1 is not set.

Dispense calib. refpos: At PURGE refpos:

default: 0

min: 0

max: 100

This item only appears if the Default Dispense option is loaded. This value is used to specify which REFOS is checked to determine whether the robot is currently at the PURGE position. PURGE position location is checked during certain dispense calibrations. This value is stored in the system variable $SLCELLSU[1].REFPOS_PURGE. For PURGE, this value MUST be set to 2.

Note that, although not displayed in this screen, the controller also stores a value to indicate which REFOS is used to determine whether the robot is currently at the HOME position. HOME position location is checked during certain dispense calibrations. This value is stored in the system variable $SLCELLSU[1].REFPOS_HOME. This value is preset to 1 and must not be changed because the UOP ATPERCH UO[7] signal only reflects Reference position #1. Refer to the "User Operator Panel (UOP) Signal Definition" section of the SpotTool+ Setup and Operations Manual for more information about the UOP ATPERCH output signal.
