Manufacturer wording — WARN %sDyn. yield > % tolerance band
The manual prints placeholders; your controller fills them in with the real group, axis or number.
FANUC PAIN-532 (“WARN …Dyn. yield > % tolerance band”): As a particular flow rate set point is being output the yield (slpm/cnt) for that flow rate was approximately larger than the percent tolerance. First check: In some way decrease the yield.

Description
As a particular flow rate set point is being output the yield (slpm/cnt) for that flow rate was approximately larger than the percent tolerance. It is not likely that the set point will be reached within the specified tolerances. This may be caused by the use of a flow rate setpoint that is above the value that the air system can provide.
Remedy
In some way decrease the yield. Use larger diameter air lines to supply air to the cap. Use a larger ratio booster (2:1 instead of 1:1) booster (if the system can not supply the high flow rates provided). Use a smaller ratio booster. Otherwise accept a larger tolerance band. Increase the Percent tolerance band (by about 50%).
