FANUC Alarm PNT1-247 — Min output has flow > setpoint
Manufacturer wording — %sMin output has flow > setpoint
The manual prints placeholders; your controller fills them in with the real group, axis or number.
FANUC PNT1-247 (“Min output has flow > setpoint”): With a minimum control output, the flow rate was measured to be higher than the flow rate setpoint. First check: Calibrating the resin will establish a new cracking pressure (minimum control output) for a changed fluid pressure.

Description
With a minimum control output, the flow rate was measured to be higher than the flow rate setpoint. The resin fluid pressure might have become too high. The I/P transducer or fluid regulator might be stuck open. Or, there might be a fairly large fluid leak. Note: Accuchop automatically faults the robot and enters into Open Loop when this failure occurs.
Remedy
Calibrating the resin will establish a new cracking pressure (minimum control output) for a changed fluid pressure. Check the resin fluid regulator and I/P transducer, and replace them if necessary.
