FANUC Alarm PNT1-634 — %sDyn. yield > min tolerance band
FANUC PNT1-634 (“%sDyn. yield > min 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: 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 might be caused by the use of a flow rate setpoint that is below the value that the air system can accurately provide.

Decrease the yield. Use larger diameter air lines to supply air to the cap. Use a smaller ratio booster. Otherwise, accept a larger tolerance band. Increase the minimum tolerance (by about 50%).
