FANUC Alarm PAIN-544 — WARN %sMax. output has flow < setpoint

FANUC PAIN-544 (“WARN %sMax. output has flow < setpoint”): With a maximum control output the flow rate was measured to be lower than the setpoint (requested flow). First check: Check, clean and possibly replace the air cap. Likely part: Air flow sensor (Air flow sensor) +1 more.

Description

With a maximum control output the flow rate was measured to be lower than the setpoint (requested flow). The Max. control out (ms) parameter effects the sensitivity of this alarm. This is likely d by a clogged air cap.

Remedy · Remède

Check, clean and possibly replace the air cap. If air is observed to be flowing (when commanded), possibly replace the air flow sensor. Check for a pinched air line. Check and repair the I/P transducer. Possibly increase the Max. control out (ms) parameter (by about 50%).
