With KRC1 one can plug motors to different plugs on PM600. make sure your PM600 is connected correctly for your robot arm type. Details are in the controller schematics. Maybe someone just happened to pair this robot + controller for the sale (maybe they both used to work with their respective counterparts but this is now fresh combo).
I will check that. But the weird part is that any axis move A3 axis it's not just inverted.
You should fix the robot on the floor, before you try other things, especially with those silly movements, you're that near to harm yourself or the robot while robot is only 'fixed' on the wooden pallet.
You will not be first who has a robot with a broken arm
Yeah, you're right, I could damage the robot, I will check if I can make a better temporary setup for my tests. For myself, It looks pretty close on the video, but only the phone is close, I'm not, but thx for caring.
Could be also wrong power cable. Kuka uses at least 2 different types of cables. Had also similar problem in the past. Than I changed cable and everything works perfectly
Yeah, that's on my list, I will check that ASAP, it's very plausible, the robot was bought working, but they maybe swapped the cable with another one by mistake.
Thx again for all your replies, I should be working on the robot tomorrow. I will give you some news soon !
