FANUC Alarm PNT2-568 — Max. output has flow < setpoint
Manufacturer wording — %sMax. output has flow < setpoint
The manual prints placeholders; your controller fills them in with the real group, axis or number.
FANUC PNT2-568 (“Max. 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 the gun tip and the whole gun for clogging. Likely part: Transducer (Transducer).

Description
With a maximum control output the flow rate was measured to be lower than the setpoint (requested flow). The gun might be clogging. A fluid or pilot air line might be pinched. The fluid pressure might have become too low. The I/P transducer might be broken. Note, Accuflow automatically changes to Open Loop when this failure occurs.
Remedy
Check the gun tip and the whole gun for clogging. Check the fluid lines for pinching, especially at places where they flex. Check the fluid supply pressure. Check and replace if necessary the I/P transducer.
