8.4. Assigning an External Axis Value to the Location

 

Control of the servo gun actually means control of the external axis, so each location should be “Compound”. However “ROBCAD/SPOT” doesn’t create “Compound” locations by classifying cases of servo gun welding separately.

Therefore, a user should assign an external axis value to a normal location created at “ROBCAD/SPOT” by using the [Update] button shown in [Figure 8.5]. ([Remove ext.] button is used for deleting assigned external axis value.)

It is very difficult for a user to process this work for a large number of locations separately. Therefore, teach pendant of Hi5 OLP package enables this process to be performed automatically.

By clicking the [Make ext. pose] button shown in [Figure 8.6], a dialog box that accepts path or locations will be displayed.

 

When selecting a welding path, an external axis value will be assigned to all locations of the corresponding path according to the rules below. In addition, external axis values can be assigned exclusively to specific locations by selecting these locations.

 

n For welding points, an external axis value will be assigned to the welding gun as a pose value, which is defined as “CLOSE”.

 

n For pass points, the external axis value will be assigned to the welding gun as a pose value, which is defined as “OPEN” or “SEMICLOSE” depending on the “po1”, “po2” setting.

 

Servo gun axis value of each location is redefined according to the rules above whenever selecting [Make ext. pose] button.
