Fanuc Robot Forum / FANUC T.A.S.T Through Arc Seam Tracking
« Last post by calintomescu on Today at 06:18:35 AM »

I`m interested in a seam tracker that can help correcting a maximum 0.5mm deviation due to minor changes in workpiece geometry (the workpiece comes from 4 identical machines, that deliver slightly different results), on welds with length varying from 30mm to 200mm .
After a small theoretical study i saw that FANUC TAST could be a perfect solution for our applications.

On paper it seams (he he) a perfect solution, but i need a practical solution. Where can i find information about this sensor from a company that actually uses it?

Have a great day !  :biggrins:

Hi all. Sorry for the late reply.

I changed the IP address as instructed, but how can I test whether the communication between the laptop and robot is established?

Thank you.

Is kind of both,

I almost graduated and i`m making the study at a big company.
We have issues with some workpieces that are not being welded propertly because of small differences in the geometry and the fact that same piece comes from multiple identical welding cells (that have different tolerances).

As you said in theory, WELDGUIDE seams (he he) like the Holly Grail but i wonder why i can`t find proper documentation on this.
I don`t expect someone to solve my problem, i`m just asking for guidance and where to find more unbiased info about this.

As i said we are a big company and we have contacts with ABB, but in our country there is only one company that uses this method.And the testimonials are only from ABB and they say it works wonders.

About the issues; i know it is restricting the torch mobility, we have errors under 0.5 mm, so it will be an almost unnoticeable weave so the torch won`t hit anything in this setup.
And for the distance to "home" how can i calculate, or approximate it ? from some videos i saw that in a V pattern (the configuration we need) i saw that [Home position = 3 x Initial displacement] so, by having a initial displacement of 0.5mm the robot will find home in 1.5 mm , which is not a problem on a 45mm weld

We are making 800+ heavy pieces per day and the process is optimized, the issue is that we have to retouch almost 200 pieces a day because of a small variation.

Edit: About the cycle time , if we increase weaving speed so in a manner that don't affect advance speed the cycle time will increase?
(except the minor triangulation in the beginning)
I mean, the welding speed will modify after adding the system?

Make sure to get a board that is guaranteed to work for your version of software.
There are many companies that can repair your DSQC363.  I would try calling some and getting a price for clearing the corrupted flash memory.

Are you getting an unexpected interrupt error while loading software?  Hate to see you buy a Robot CPU and it not fix the problem, but it is hard to track down software loading errors without spare parts.
Fanuc Robot Forum / Re: Roboguide Virtual Robot Controller as Modbus Slave
« Last post by zbc on Today at 02:31:54 AM »
I test on real robot controller and the Modbus connection is success. Maybe there are some settings I missed in RoboGuide?

To read DO[129], poll address is 10000 when $MODBUSTCP.OUTPUTBASE is 10000.
But fail to write any DI. I don't know if address is wrong or the controller disables permission for written.

is this necessary to connect robot with control cabinet before startup?
You do not have to connect the robot to the controller to power the controller, it will get you farther than the "PROG UNIT COMMUNICATION FAULT" message if the controller is booting up.  If it does boot, it will give 506 errors related to resolvers.
Good luck!!

Thank you ADMAN.
Your reply saved a lot of my time and effort.

It will, but the same if the gearbox and all hardware is sized properly it will be fine during the estop as well.

I think thats about what we paid for it.

Its best you get a formal quote from FANUC.

Thank you for your reply.

I have contacted a local Fanuc branch to know how much it is before I purchase the S/W.
But the price so much higher than I saw one by searching thru the internet. (
I know the price on the web page is the price of almost 10 years ago, but the price that offered by my local Fanuc is still too high. (around 6000 USD for PCDK runtime)
I wonder I should accept that with thinking the price is reasonable and I also wanted to know much they who live EU or US pay for the same license.

It would be very helpful for me to let me know how much you paid for the PCDK runtime license.
