FANUC Alarm PNT2-246 — 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 PNT2-246 (“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 resin gun may be clogging. The resin or pilot air line might be pinched. The resin fluid pressure might have become too low. The I/P transducer might be broken. Note: Accuchop automatically faults the robot and enters into Open Loop when this failure occurs.
Remedy
Check the gun tip and the whole gun for clogging. Check the resin lines for pinching, especially at places where they flex. Check the resin supply pressure. Check and replace the I/P transducer if necessary.
