Mir robot moves joint with pallet off limits for no good reason


I have few mir robots in my layout, that feed palets to respektive works processes. But when it takes pallet from conveyor next to robot on the left, it moves its join too low. When it picks up pallet from the conveyor with the pallet feeder on the right, it works normally. Has anyone encountered same problem? Any help is greatly appreciated. Thanks in advance.
