2.4.1. Autosetting
Press “[F1]: All autosetting” to progress the autosetting for the application setting of the servo gun. In the “All autosetting” mode, the moving tip of the servo gun will automatically move. In addition, the following conditions must be satisfied because the setting value is affected by the squeeze force.
- Attachment of a new tip to the moving and fixed electrodes
- No presence of workers near the servo gun
- No workpiece between the moving and fixed tips
- Manual mode
- Motor on
- Completion of the basic setting (Step 1) of the servo gun
In the “All autosetting” mode, the following procedures will be automatically performed.
(1) Gun search
- Executes gun search while squeezing the servo gun two times
- First time: “Gun search reference location record” enabled
- Second time: “Gun search reference location record” disabled
(2) Gun arm bending compensation
- Compensate the bending while squeezing the servo gun five times
(3) Panel thickness measurement compensation
- Compensate the bending while squeezing the servo gun five times
Caution: If you proceed with “Autosetting,” you can only perform gun search.
1. If gun searches other than gun search 1 needs to be used, refer to the “Gun Search” chapter of “Work teaching.”
In the “All autosetting” mode, the “Gun arm bending compensation” and “Panel thickness measurement compensation” will be performed, and at the same time, the servo gun squeeze will be performed only five times.
To execute “Gun search,” you should designate the squeeze force and gun search speed. If you press [F4]: Gun search condition setting』 in the previous “Application setting” screen, you can set the squeeze force and moving speed that can be used for the Gun search shown below.
Caution) As far as “gun arm bending compensation” and “panel thickness measurement compensation” are concerned, it is recommended to use the automatic setting because it is difficult to perform measurement and manually fill the values.
The “Gun arm bending compensation” value is the one to be used in place of the “Gun arm bending / 100 kgf [mm]” among servo gun parameters. If the “Gun arm bending compensation” setting is performed, the “Gun arm bending / 100 kgf [mm],” which is set in advance, will not be used. On the contrary, if the “Gun arm bending compensation” is not set, the “Gun arm bending / 100 kgf [mm]” will be used.
The configuration and functions of the servo gun application setting screen are as follows.
1) Status: Presents the state of the servo gun (Not set, Completed, or Changed)
2) Individual autosetting: Supports the automatic setting of only the checked items, not all. If you press 『[F2]: Autosetting of selected items』, only the checked items will be automatically progressed.
3) Manual setting: Moves to the screen to set each relevant item
- Gun arm bending compensation
Automatically moves to the『[F2]: System』 → 『4: Application parameter』 → 『1: Spot welding』 → 『3: Welding gun parameter』 screen
- Panel thickness measurement compensation
Automatically moves to the『[F2]: System』 → 『4: Application parameter』 → 『1: Spot welding』 → 『3: Welding gun parameter』 screen
4) Guide: Indicates the present setting status or the cause of the error and action plan
5) Monitoring: Displays the present setting status, servo gun location, return current and set values, etc.
6) All autosetting: Commands to execute all autosetting
7) Autosetting of selected items: Performs autosetting of the items designated for individual autosetting
8) Execution on hold: Stops the setting in progress
9) Gun search condition setting: Sets the speed and squeeze for gun search
