Greetings !
I tackled the System ladder of our robot as i want to learn how it actually functions.
Im having some troubles understanding some adresses, what exactly they are.
Lets take "Line 14" on the bellow picture as an example.
Are adresses #70364 , #70267 and #70243 auxiliary relays which are used to map/save certain signals ( for example wire sticking checking) and are then further used as a signal.
If i understand correctly, the parameters S4C080-S4C095 are used to clear/hold the statuses of theese relays upon powerup/poweroff.
In this line, #70243 is the exit (Q). When the requirements are met does that turn the bit in #70243 into a 1 ?
We would want to implement a signal that would tell us if a welding arc has been established. For example using something like a current Clamp to measure if there is actual current running and then map that signal to one of theese auxiliary relays and use the said signal in the ladder for producing an alarm & stopping the robot.
Currently the problem is as follows: Robot will start a weld, the wire will sometimes get burned off and welded to the nozzle. The robot will continue through the program untill it gets to the next ARCON instruction where it then stops beacuse of alarm 9001 - Missing Arc start confirm ( signal logic that arc start cannot be performed).
Then it is uppon the operator of the robot to guide the robot to the spot where the welding actually stopped and restart the program ( which is a problem because our operators arent really schooled to be doing that).
Thats why we would like to implement a signal that would stop the robot immediately when there isnt an arc established when it should be.
Ty for all the help and clarification on this topic.
