STATUS SERVOGUN SCREEN


STATUS SERVOGUN SCREEN

status/servo gun

You can display the status of the servo gun in a SpotTool+ system that uses a servo gun on the STATUS Servogun screen.

The STATUS Servogun screen displays the items in Table 1, " STATUS Servogun Screen Items " .

Table 1.  STATUS Servogun Screen Items

ITEM DESCRIPTION

Pressure schedule

Indicates the pressure schedule number specified for the spot welding instruction being executed. If no spot welding instruction is being executed, the Pressure schedule for the most recently executed spot welding instruction is indicated.
  • Pressure schedule number is specified by the P=#, in the spot instruction.

  • The pressure schedule contains all data for the pressure position: weld force, thickness, gun sag compensation value, etc.

Start distance schedule

This item indicates the start distance schedule number for the spot welding instruction being executed. This index defines an open distance for the movable tip and stationary tip, enroute to the spot weld location.

End distance schedule

This item indicates the end distance schedule number for the spot welding instruction being executed. This index defines an open distance for the movable tip and stationary tip when opening from the spot weld location. However, there is no end distance schedule for a press_motion instruction: end distance schedule= 0 for press_motion.

Tip Wear value (Gun) (mm)

This item indicates the wear amount of the movable tip

Tip Wear value (Robot) (mm)

This item indicates the wear amount of the stationary tip

Pressure value (kgf)

This item indicates the pressure applied during the execution of a spot welding instruction. The indicated pressure is obtained by subtracting a dynamic friction portion from the specified torque (corresponding to a disturbance torque) and multiplying the difference by a pressure conversion coefficient. The indicated value is therefore, a rough estimate of the pressure actually applied between the tips

Current position (Gun)

This item indicates the current gun position on the gun axis.

Thickness check:

The following parameters provide thickness check status data. Thickness status data is set at check (after force is achieved).

Thickness status data is cleared at:

  1. 1. Gun close

  2. 2. Task end

****** is displayed after thickness check data is cleared.

Prog, line:

This item specifies the program name and line number of spot/pressuring motion where thickness check is being performed.

Specified thickness (mm)

This item indicates the expected (target) part thickness specified via pressure schedule or local condition.

Observed thickness (mm)

This item indicates the measured (estimated) part thickness.
