Somewhere last week i had a problem with one of our robots (kr150 +krc2). It gave a axis overload on axis 1,3 en 6 during a circular movement. Now i know that this can happen during fast circular movements, especially in small cirkels so at the time i didn't worried about it. When i thought about it some more though is was wondering why a programmed motion that has been run for maybe 500 times or more suddenly gives a overload error. after i got the overload last week I have not seen it return since either so for now it is limited to a single event.
Some more information about the circmovement:
$APO.CVEL = 50
$VEL.CP = 0.3
LIN{z -20} C_VEL
CIRC{x 72,z -96},{x 0,z -168}, CA 360 C_VEL
during this movement the robot uses a circular saw to cut the end of piece of plastic pipe.
Bases on this information, is there something i should worry about? or do these things sometimes just happen?
