n P1-10: Low Feedback Selection
Selects the drive response to a Low Feedback condition. When the PID feedback falls below the P1-08 setting for the time set
in P1-09, the drive will respond based on the setting in P1-10.
No. Parameter Name Setting Range Default
P1-10 Low Feedback Selection 0 to 2 0
Low feedback detection is enabled when:
• P1-08 > 0.0
• Drive is running in AUTO Mode, including sleep boost and feedback drop detection (standard PID, b5-09 = 0)
• Run Command is present (including sleep and timer operation) (inverse PID, b5-09 = 1)
Setting 0: Fault
When feedback drops below the P1-08 level for longer than the time set in P1-09, the drive will fault on the “LFB – Low
Feedback” fault and coast to a stop.
The digital output programmed to “Low Feedback” (H2-0o = 97) closes. The drive will also display the “Low Feedback –
Low FB Sensed” alarm. The digital output will remain closed until the fault is reset.
Setting 1: Alarm
When feedback drops below the P1-08 level for longer than the time set in P1-09, the digital output programmed to “Low
Feedback” (H2-0o = 97) closes and the drive displays the “Low Feedback – Low FB Sensed” alarm.
When feedback rises above the level determined by P1-08 and P1-14, or when one or more of the conditions that enable low
feedback detection are no longer true, the digital output will open and the alarm will clear.
Setting 2: Digital out only
When feedback drops below the P1-08 level for longer than the time set in P1-09, the digital output programmed to “Low
Feedback” (H2-0o = 97) closes.
When feedback rises above the level determined by P1-08 and P1-14, or when one or more of the conditions that enable low
feedback detection are no longer true, the digital output will open.
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.
