Hi all,
I want to know if kuka considerate the posibility of increase the load if you work with the wrist alwais in vertical ,like if it was a paletizing robot.
For example ABB allows you to increase the load +/- 10% like you can watch in the attached picture.
thank you 
Yes. $PAL_MODE should let most 6-axis KRs act as if they are 4-axis palletizing robots. This will also increase the payload capacity by some degree, but exactly how much is a question you would probably need to ask KUKA. IIRC, a KR500 in Palletizing Mode could lift up to 570kg.
