FANUC PNT1-576 (“Max. flow below mid point”): This alarm occurs only during calibration. First check: Increase the fluid pressure.

Updated 2026-09-17 · LogrobotLM reference

Description

This alarm occurs only during calibration. The flow rate measured at the maximum control, and one half of the maximum control output was nearly the same. Less than one half of the control output range is useable. The system might still function even though this alarm has occurred. This might be caused by low fluid pressure, a faulty transducer or regulator, or by having the wrong I/P transducer installed (100 psi range instead of 50 psi range).

Remedy

Increase the fluid pressure. Check that the transducer is functioning properly and that it has the correct pressure range. Change the range if appropriate. The system might operate, but performance can be improved with one of the above remedies.
