Flexpicker arm check point limit

We have a IRB360 pickmaster setup where the robots intermittently will fault by "50138: Arm check point limit, The robot ROB_1 has reached the limit for arm check point."

- What defines the arm check point? Is this a axis / arm limitation or is the TCP out of its work area?
- Are the limits for the arm check point adjustable?
- Is it possible to programmatically recover from this error without halting the IRC5 robot controller?

When i look at the controller topic "Arm Check Point" under "Motion" in RobotStudio i find that this topic is empty. Is this a topic reserved for articulated robots? Why is it still failing "arm check point"?
