◆ P2-17 No-Flow Feedback Delay Time

Setting Range: 0.0 ~ 1000.0 s

Factory Default: 2.0 s

The iQpump drive can be configured to activate a no-flow detection by programming the No-Flow Activation Level (P2-11). When the

no-flow detection process is activated, and the system setpoint has returned to the original value, the feedback will be monitored. If the

feedback level is within the No-Flow Delta Feedback Level (P2-15), a specific delay time can be programmed in the No-Flow Feedback

Delay Time (P2-17) before the drive enters a “sleep” mode.

The No-Flow Feedback Delay Time (P2-17) works in conjunction with the No-Flow Delta Feedback Level (P2-15).

Refer to the No-Flow Activation Level (P2-11) for more details.

◆ P2-18 No-Flow Motor RPM Sample Time

Setting Range: 0.0 ~ 1000.0 s

Factory Default: 2.0 s

The iQpump drive can be configured to activate a no-flow detection by programming the No-Flow Activation Level (P2-11). The no-flow

detection function monitors the motor rpm. The motor rpm monitor sample rate can be programmed in the No-Flow Motor RPM Sample

Time (P2-18).

Refer to the No-Flow Activation Level (P2-11) for more details.

◆ P2-19 No-Flow Feedback Detection Direction

The iQpump drive can be configured to activate a no-flow detection by programming the No-Flow Activation Level (P2-11). When the

no-flow detection process is activated, and the system setpoint has returned to the original value, the feedback will be monitored. The

direction of the feedback upon return of the no-flow detection can be selected by programming the No-Flow Feedback Detection

Direction (P2-19).

The No-Flow Feedback Detection Direction (P2-19) works in conjunction with the No-Flow Delta Feedback Level (P2-15).

Refer to the No-Flow Activation Level (P2-11) for more details.

◆ P2-20 Alternative Sleep Activation Level

Setting Range: 0.0 ~ 6000.0 <0034>

Factory Default: 0.0

The iQpump drive can be configured to activate a “sleep” mode. In addition, the iQpump drive can be configured to activate an alternative

“sleep” mode. When the Sleep Level Type (P2-01) is set for a value of 0 (P2-01 = 0: Output Frequency), the alternative sleep activation

level is set when a value greater than 0 is programmed in the Alternative Sleep Activation Level (P2-20).
