I am pretty new to Industrial Robots (6 months working in this field) and I am currently working on a Robotic Milling plant for Foundry with a Fanuc M900iB400L.
We build complex processes by using small TPP as building blocks and combining them with KAREL programs; we got this problem where, in automatic mode, one of those TPP stops and gives error MOTN-018 Position not reachable.
We checked most common causes like changes in configuration or outside of robot envelope, but everything seems ok.
When we try to reach the same point in manual (starting in the same settings) the robot moves normally to the point and gives no alarm.
The same happens if we try to execute the same TPP in automatic mode but with reduced override speed.
Anyone has any idea?
Thanks in advance!
