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.

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.

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

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” (H2-0
o
= 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.
Setting 1: Alarm
When feedback rises above the P1-11 for longer than the time set in P1-12, the digital output programmed to “High Feedback”
(H2-0
o
= 96) closes and the drive displays the “High Feedback – High FB Sensed” alarm.
When feedback falls below the level determined by P1-11 and P1-14, or when one or more of the conditions that enable high
feedback detection are no longer true, the digital output will open and the alarm will clear.
Setting 2: Digital out only
When feedback rises above the P1-11 for longer than the time set in P1-12, the digital output programmed to “High Feedback”
(H2-0
o
= 96) closes.
When feedback falls below the level determined by P1-11 and P1-14, or when one or more of the conditions that enable high
feedback detection are no longer true, the digital output will open.

P1-40: Maximum Pump Speed
Sets the maximum pump speed determined by the smallest value among P1-40, E1-04, and d2-01. This parameter is not
effective when set to 0 or when set higher than E1-04 x d2-01.
When this parameter
≠
0, maximum pump speed is internally lower limited to the minimum pump speed (largest setting among
P1-06, P4-12, and d2-02).

Parameter available in drive software versions PRG: 8552 and later.
