YASKAWA TM.iQp.07 iQpump Controller Programming Manual 149
The iQpump drive can be configured to display a Low Feedback (LFB) alarm when the feedback level falls below the programmed Low
Feedback Level (LFB). The “LFB” alarm will turn off when the feedback level rises above P1-07 plus the Hysteresis Level (P1-13).
Setting P1-07 to a value of 0 will disable this function. This function is only active during operation in the Auto Mode.
The Low Feedback Level (P1-07) works in conjunction with Low Level Fault Time (P1-08). The units for this parameter are determined
by the System Units (P1-02).
◆ P1-08 Low Level Fault Delay Time
Setting Range: 0 ~ 3600 s
Factory Default: 5 s
The iQpump drive can be configured to display a Low Feedback (LFB) alarm when the feedback level falls below the programmed Low
Feedback Level (P1-07) for the time programmed in the Low Level Fault Delay Time (P1-08).
Setting P1-08 to a value of 0 will disable this function. This function is only active during operation in the Auto Mode.
The Low Level Fault Delay Time (P1-08) works in conjunction with Low Feedback Level (P1-07).
If P1-01 = 3, the function will stop all drives running on the network when the system fault occurs. <0034>
◆ P1-09 High Feedback Level
Setting Range: 0.0 ~ 6000.0
Factory Default: 155.0 (system units P1-02)
◆ P1-10 High Level Fault Delay Time
Setting Range: 0 ~ 3600 s
Factory Default: 2 s

Low Feedback Level Fault Delay
Time
Low Lvl FLT Time
System will fault LFB/LW “Low Feedback / Water” fault when
feedback level falls below the programmed level for a time specified
in P1-08.
On fault the drive will coast to a stop.
A value of 0 disables this function. This function is only active during
running while operating in auto mode. If P1-01 = 3, function will stop
all drives running on the network when the fault occurs (system
fault).

High Feedback Level
High FB Level
System will show alarm (HFB) when feedback level rises above the
programmed level. The alarm will turn off when the feedback level
falls below the programmed High Feedback Level minus the
Hysteresis Level (P1-13)
This function is active during running in Hand Mode, Auto Mode,
Pre-charge and Thrust bearing Mode. If P1-01 = 3, parameter P9-18
uses this value to calculate the quick de-stage feedback level.
