◆ P2-12 No-Flow Detection Bandwidth
Setting Range: 0 ~ 1000 rpm
Factory Default: 15 rpm
The iQpump drive can be configured to activate a no-flow detection by programming the No-Flow Activation Level (P2-11). The no-flow
activation can have a programmed bandwidth before the no-flow condition is activated by programming the No-Flow Detection
Bandwidth (P2-12).
The No-Flow Detection Bandwidth (P2-12) sets the motor rpm fluctuation bandwidth. The no-flow detection activates when the motor
rpm is below the No-Flow Activation Level (P2-11) and remains within the programmed No-Flow Detection Bandwidth (P2-12) for a
time specified by the No-Flow Detection Time (P2-13).
The No-Flow Detection Bandwidth (P2-12) works in conjunction with the No-Flow Activation Level (P2-11).
Refer to the No-Flow Activation Level (P2-11) for more details.
Note: Sleep function P2-02 is enable (P2-02 > 0)
