6. Frequently Asked questions

 

n  How will the servo-gun axis move if the shift function is used?

All functions (offline, online, search, palletize) for shift will be only applied to the robot axis, and the servo-gun axis will move to the record location.

 

n What will happen to the servo-gun axis at the time of coordinate conversion? 

Only movement elements for the robot will be converted, and the servo-gun axis will not be converted.

 

n If operating the relative program call function, how the system will be operated?

Shifting will be carried out by applying only the relative location for the robot.

 

n What will happen to the servo-gun axis at the time of mirror image conversion?

At the time of mirror image conversion, only the additional axis with a “base” for axis specification and “direct-acting” for axis structure will be applied. All other cases are not applicable. Therefore, the Servo-gun axis will not be converted.

 

n I would like to change the currently selected gun number

The currently selected gun number can be changed by “R210: Spot-Gun Number select”. If the gun type you desire to change is robot-gun, the tool number will be changed at the time when the gun number is changed by referring to Tool No. corresponding to Gun No. While in the multi-gun setting, if the gun number is changed using R210, the environment will change to the selected single gun environment.

 

n I’m trying to execute manual squeeze simultaneously by selecting multi-gun. How can I select multi-gun?

Multi-gun can be selected only for guns with same gun type. It can be changed by “R214: simultaneous welding gun select”. To deselect specific guns after selecting multi-gun, it is needed to enter the specific gun numbers using R214. However, it is impossible to deselect the first gun number (master gun).

 

n I want to change squeeze force at the time of servo-gun manual squeeze.

If the gun type of the selected gun is servo-gun, it can be changed by “R211: Servo-gun squeeze force setting”.

 

n I want to change the moving tip consumption for servo-gun at my discretion.

If the gun type of the selected gun is servo-gun, it can be changed by “R212: Servo-gun moving tip consumption preset”. When executing gun search, this value will be updated again automatically.

 

n I want to change the fixed tip consumption for servo-gun at my discretion.

If the gun type of the selected gun is servo-gun, it can be changed by “R212: Servo-gun fixed tip consumption preset”. When executing gun search, this value will be updated again automatically

 

n I want to change the fixed tip consumption for the EQless-gun at my own discretion.

If the gun type of the selected gun is EQless-gun, it can be changed by “R220: EQless-gun fixed tip consumption preset”. When executing gun search, this value will be updated again automatically.

 

n The robot is currently working automatically, and I want to change the squeeze force of the welding condition. How can I do it?

Even if the robot is currently working automatically, the squeeze force of the welding condition can be changed by using “R215: Spot welding condition squeeze force setting”.

 

 

n Can I manually change the currently selected welding condition number and welding sequence number?

Welding condition can be changed by pressing the [cond.sel] user key, and welding sequence can be changed by pressing the [seq.sel] user key.

 

n Is there any short-cut key for entering the 『[F2]: System』 → 『4: Application parameter』 → 『1: Spot welding』 menu?

You can open that menu quickly by placing the cursor on commands (SPOT, GUNSEA, IGUNSEA, EGUNSEA) related to spot welding at the manual mode initialize side, and clicking [QuickOpen]

 

n How can I change the panel thickness manually?

As long as the selected gun type is servo gun, you can change it using “R220: Panel thickness setting (Sv)”

 

n How can I change the overall recording locations of the spot welding steps to the normal values ?

In 『[F2]: System』 → 『4: Application parameter』 → 『1: Spot welding』→ 『2: Environment settings』, you can do this simply by setting the “servo gun welding step recording location auto adjustment” as  <Enable>. Then, play back the work program.

 

n Is it possible to detect whether a welding point has been missed?

First, initialize the welding execution count in the work program start section and then carry out welding normally. Then, the welding count will increase. When the work is completed, compare the number of points and the count of the executed welding. To achieve this,  you just need to carry out the programming as shown below.

 

 

n While the robot is in the process of handling, is it possible to shorten the work time while independently carrying out the tip dressing and gun search for the stationary servo gun ?

It is possible simply by using the multitasking function. Refer to the multitasking function manual provided separately.
