n P1-11: High Feedback Level
Sets the level at which a High Feedback alarm or fault will occur. When the PID feedback rises above the P1-11 setting for
the time set in P1-12, the drive will respond based on the setting in P1-13.
No. Parameter Name Setting Range Default
P1-11 High Feedback Level 0.0 to 6000.0 155.0 PSI
n P1-12: High Feedback Level Fault Delay Time
Sets the delay time after which a Low Feedback alarm or fault will occur. When the PID feedback rises above the P1-11 setting
for the time set in P1-12, the drive will respond based on the setting in P1-13.
No. Parameter Name Setting Range Default
P1-12 High Feedback Level Fault Delay Time 0 to 3600 s 5 s
n P1-13: High Feedback Selection
Selects the drive response to a High Feedback condition. When the PID feedback rises above the P1-11 setting for the time
set in P1-12, the drive will respond based on the setting in P1-13.
No. Parameter Name Setting Range Default
P1-13 High Feedback Selection 0 to 2 0
High feedback detection is enabled when:
• P1-11 > 0
• Run Command present, including sleep & timer operation (standard PID, b5-09 = 0)
• Drive is running in AUTO Mode, including feedback drop detection (inverse PID, b5-09 = 1).
Setting 0: Fault
When feedback rises above the P1-11 for longer than the time set in P1-12, the drive will fault on the “HFB – High Feedback”
fault and coast to a stop.
The digital output programmed to “High Feedback” (H2-0o= 96) closes. The drive will also display the “High Feedback –
High FB Sensed” alarm. The digital output will remain closed until the fault is reset.
