FANUC Alarm PNT2-556 — Dyn. yield > tolerance band (%s)

FANUC PNT2-556 (“Dyn. yield > tolerance band (%s)”): As a particular flow rate set point is being output, the yield ((cc/min)/cnt) for that flow rate was larger than the tolerance band for it. First check: Decrease the yield.

Updated 2026-08-29 · LogrobotLM reference

Description

As a particular flow rate set point is being output, the yield ((cc/min)/cnt) for that flow rate was larger than the tolerance band for it. It is not likely that the set point will be reached. This might be due to the restricters in the gun being too large.

Remedy · Remède

Decrease the yield. Use smaller restricters in the gun if the high end flow rate can still obtained. Otherwise, accept a larger tolerance band. If the value given in the alarm is equal to the Minimum tolerance band, set the minimum tolerance band equal to the yield for that color. Otherwise, increase the Percent tolerance band.
