Hello all. I have fanuc robot arcmate 100i with rj2. I want to ask 2 issue of how it operates. . .
Problem 1:
I want to teach robots moving circle. I have reference material is known to teach the circle, the command structure is as follows:
J P [1]
C P [2]: intermediate point
P [3]: destination point
I want to ask is when record point P [3] I have to manipulate how?
Problem 2:
My current robot after about 27s if not scrolling it automatically disconnect the power servo. Which of my robot axes can not break like that are so annoying. I want to know is there any way to increase the timeout or disable this function.
Please help me resolve... Thanks
