SETPOINT
SET-POINT NOT MET
P1-16
Setpoint-LOP Time
The drive will display a “Setpoint Not Met” fault when the drive is unable to maintain the
programmed system setpoint due a problem with the pump system.Set P1-15 to the maximum allowed difference
between setpoint and feedback level.
P1-15 Maximum Setpoint Diff
8.6 Low/High Feedback Level Detection
The drive continuously monitors the system feedback signal. Set the low feedback level parameter P1-08 to the minimum feedback level
allowed for your system to display a “Low Feedback” fault. Set the high feedback level parameter P1-11 to the maximum feedback level
allowed to display a “High Feedback” fault.
