FANUC Alarm PNT2-585 — CH2:Dyn. yield > tolerance band
Manufacturer wording — CH2:Dyn. yield > tolerance band (%s)
The manual prints placeholders; your controller fills them in with the real group, axis or number.
FANUC PNT2-585 (“CH2:Dyn. yield > tolerance band”): 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: In some way decrease the yield.

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
In some way 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 minimum tolerance band equal to the yield for that color. Otherwise, increase the Percent tolerance band.
