No.
P1-11
<1> Range is 0.0 to 999.9 with sign-bit "+" indicating Delta to Setpoint.
Range is 0.0 to 6000.0 in drive software versions PRG: 8551 and earlier.
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.
P1-12
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.
P1-13
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.
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"
(H2-0o= 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"
(H2-0o= 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.
n 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).
Note: 1. Parameter available in drive software versions PRG: 8552 and later.
2. Parameter not available in drive models 4A0930 and 4A1200.
No.
P1-40
n P2-01: Sleep Level Type
Selects which data source the drive will use to determine if it should activate the sleep function. This parameter is application-
dependent and should be set in conjunction with the type of system data is available. Choose the data type that best represents
a low-activity condition for the system.
Note: Set this parameter prior to changing other parameters related to the Sleep Function, as internal scaling is based on P2-01.
