FANUC Alarm PAIN-552 — WARN %sDyn. yield > min tolerance band

FANUC PAIN-552 (“WARN %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: 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 d by the use of a flow rate setpoint that is below the value that the air system can accurately provide.

Remedy · Remède

In some way 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%).
