Manufacturer wording — WARN %sCal. table adapted out,output up
The manual prints placeholders; your controller fills them in with the real group, axis or number.
FANUC PAIN-500 (“WARN …Cal. table adapted out,output up”): The relationship of the output command to the flow rate obtained has changed significantly since the last calibration. First check: Check, clean and possibly replace the air cap. Likely part: Air cap (Air cap (paint atomizer)).

Description
The relationship of the output command to the flow rate obtained has changed significantly since the last calibration. There is now a larger output required to get the same flow rate. This can be caused by: a clogged air cap, clogged gun, pinched air lines or large losses of air supply pressure. Note that the system continues to close the loop and generally maintain requested flow rates even after this alarm if there are no other alarms occurring. This alarm can provide early warning of the possible failures. This alarm is controlled by the Adaptive tolerance parameter.
Remedy
Check, clean and possibly replace the air cap. Check for a large loss of air supply pressure. Check for pinched air lines or clogged air passages in the gun. Recalibrate to immediately clear the alarm. Increase the Adaptive tolerance parameter to allow larger changes without alarming
