But can I do this for individual points? I want to use data entered through the PLC to offset individual points on the Z axis. Is this possible with panasonic?

We use touch sensing to offset all the points in a weld program. Is there is a way to offset individual points separately?
Thanks

Thanks HawkMe and djogf412. I will check the PLC.

I was able to watch the UI's today. UI 8 was dropping out right before the weld started. The alarm was SYST-032 ENBL signal lost from UOP. The only way to fix this was to Function/Abort All and call my master program again. It doesnt do it again after that.

Ok I will try this on Monday. Thanks!

Its being controlled remotely through PLC, im not sure if thats what you are asking. It was set up by an integrator so Im not sure what other info you are looking for. I didnt have any problems like this until I ran this particular program.All other programs run fine. I have this same program on newer robots and I dont have this issue.

I wrote a weld program that calculates a perfect circle. It uses 2 Position registers that are set on each side of the circle. The Y data from these 2 points are used to calculate the center point and radius. I made a formula that will use the information to calculate all the coordinates for 9 points around a perfect circle. My 9th point being the overlap. My goal was to make a program that does not need to be adjusted on X,Y, W,P, or R. Team leaders can only adjust the Z. I am using a PR offset for each point that gets the offset data from a register. My plan is to set this up on the HMI screen so they wont even have to touch the controller. But to test it out I'm offsetting by putting numbers directly into the registers. I'm not using Lock/Unlock PREG because I want them to have the option to use the controller if something were to happen. So at start up, when i run the first part, the robot moves to the point before the first point (PR) of my circle and stops. It says UOP signal lost and will not advance. The only way to get it to run is to take it back to home position, reset everything and run again. It will work the rest of the time unless the controller is used during the program to teach a point and it is restarted from the beginning of the weld. I'm thinking that if I used Lock/Unlock PREG this might fix the problem but I'm looking for a way around this.
This is an example of my points:
89:L PR[10] WELD_SPEED FINE
: Arc Start[1] Offset,PR[20] ;
90:C PR[11] Offset,PR[21]
: PR[12] WELD_SPEED CNT100 Offset,PR[22] ;I appreciate any input. Thank You.
