Hi
A visual check of the base cable assembly in motion can spot clues to quickly point out the base cable is the issue. E-Stop controller. Remove the base cover where the air line is (4x T30 screws) and look into the entire base cavity. It is useful to have (3) people, (1) to hold axis 1 manual brake button in, (1) to push axis 1 thru it's range of motion & (1) to view the base cable while it moves. The base cable is bad if:
We did that hand found out the the IRB2 cable was damage and we replace it. Now we have no more error on IRB2 only IRB1. Also when we turn the base with the Manual Brake off button the error change to : Motor over current 39222 IRB1 and then Back to short circuit IRB1. I feel strange that we could damage 2 cables in a single move (no crash just stop in the middle of auto cycle). It's a old robot so i guess anything can happen. When we look at it the IRB1 cable look very hard to replace because it rotate with the base. Any sugestion ? we are going to move it very very slowly to check for cable damage.
