Hello
I'm having a problem with a couple spot welding robots my company is integrating.
When we run the cell in "WELD MODE" everything is fine, PLC gets weld completes from the Bosch timer so I know the BG logic I'm using for the weld completes is correct.
When we try to dry cycle the robot in "NO WELD MODE" some of the robots get "SPOT-008 Weld Complete Timeout Fault".
We noticed if we enable "sim weld IO" under the "TEST CYCLE>SPOT WELD" the robot will continue but this creates another problem. When we enable "sim weld IO" the PLC no longer sees the weld complete signals and puts a hold on the robot because it thinks its missing welds.
We have quite a few other robots in the same cell that don't have this problem. They can run in "NO WELD MODE" with "Sim weld IO" disabled and the PLC gets the weld completes. I have compared everything everything I can think of between the two robots (weld interface, io interconnects, cell interface, spot config, spot equipment, BG logic,) and nothing seems to be different.
Any one ever experienced this or have any ideas on something i might be missing? Any help is appreciated
Thanks
Lucas
