SETUP SPOT EQUIP SCREEN


SETUP SPOT EQUIP SCREEN

Spot equipment setup allows you to define the configuration and timing sequence of equipment between all the weld inputs and outputs during the weld sequence. A setup menu exists for each equipment defined during configuration setup. Default values are supplied.

Table 1.  Spot Equipment Setup

SELECTION DESCRIPTION

Anticipation type(milliseconds or millimeters)

default: TIME

min: TIME

max: DISTANCE

This item defines whether the close backup and close gun time values are in time or distance, where

  • time - is set in milliseconds

  • distance - is set in millimeters. Distance is only valid for linear motions. Distance is not typically used in spot welding applications.

    Cycle time benefits often can be realized using these anticipation settings.

Close gun (milliseconds or millimeters)

default: 150

min: 0

max: 10000

This item defines the amount of time in milliseconds, or distance in millimeters from, the weld position at which the gun starts to close. Distance is only valid for linear motions. NOTE If speed changes are made in the program, the distance is still valid.

Weld Start Delay (milliseconds)

default:

min: 0

max: 10000

This is the amount of time the robot will delay once it reaches the point before it initiates the weld controller.

Close backup (milliseconds or millimeters)

default: 300

min: 0

max: 10000

This item defines time in milliseconds before, or distance in millimeters from, the weld position at which the backup starts to close. Distance is only valid for linear motions. NOTE If speed changes are made in the program, the distance is still valid.

Open gun time (milliseconds)

default: 0

min: 0

max: 10000 ms

This item defines the delay time in milliseconds, to allow the gun to open after completion of the weld, prior to moving to the next position.

Open backup (milliseconds)

default: 0

min: 0

max: 10000 ms

This item defines the delay time in milliseconds, to allow the backup to go from half open to full open (backup open) prior to moving to the next position.

Spot count R[n] orGun x spot count R[n] if

you have dual guns

default: 1

min: 1

This item is used as a counter for all spot welds executed by gun 1, where [n] equals the register number. This includes all welds performed during test run, as well as all manual welds.

Tip dress R[n]

default: 10

min: 1

This item can be compared to the spot count register to decide if a tip dress is required.

Target Welds/Dress

This item is the user-specified number of welds that should be done before a tip dress. This value is set in $spoteqsetup[equip_number].$td_limit[gun_number].

If you have an iPendant, this value is used in the bar chart on the Spot Status menu to show you the percentage of welds until trip dress is required.

Dropoff Gun1 Macro

Used for stud welding only, and only if stud backup is enabled at controlled start

This item allows you to specify the name of the predefined program to be used for the dropoff during stud welding, for gun 1.

Pickup Gun1 Macro

Used for stud welding only, and only if stud backup is enabled at controlled start.

This item allows you to specify the name of the predefined program to be used for the pickup during stud welding, for gun 1.

Dropoff Gun2 Macro

Used for stud welding only, and only if stud backup is enabled at controlled start

This item allows you to specify the name of the predefined program to be used for the dropoff during stud welding, for gun 2.

Pickup Gun2 Macro

Used for stud welding only, and only if stud backup is enabled at controlled start

This item allows you to specify the name of the predefined program to be used for the pickup during stud welding, for gun 2.

Valve Pressure for Backup and Soft Touch Pressures

Gun Open

default: 0

This item allows you to set the Gun open pressure according to the equipment you are using Refer to Figure 1, " Valve Pressure Settings " for the valve pressure settings timing diagram.

Backup Pressure

default: 0

This item allows you to set the backup pressure according to the equipment you are using. Refer to Figure 1, " Valve Pressure Settings " for the valve pressure settings timing diagram.

Soft Touch Pressure

default: 0

This item allows you to set the soft touch pressure according to the equipment you are using. Refer to Figure 1, " Valve Pressure Settings " for the valve pressure settings timing diagram.
