5.3 Pump Protection
◆ P2 Shutdown Pump System When Running at Low Speed (Sleep)
■ P2-01, P2-02, P2-03
To protect the pump from operating at very low speeds causing excessive pump wear the iQpump drive offers a function to shutdown
(Sleep) the pump system.
■ Select Signal to Monitor
The system level to monitor no-flow operation can be selected with parameter P2-01 Sleep Level Type :
Table 5.9
■ Setup Sleep Level (P2-02)
Sleep Detection level can be setup with P2-02 Sleep Level . The Sleep Level units for P2-02 depend on the selection of parameter P2-01
(System Units).

Sleep Level
Sleep Level
Sleep activates when selected level (P2-01) reaches programmed sleep level
for time specified in P2-03. The level type is determined by
P2-01. A value of 0 disables this function. This function is only active
during running while operating in auto mode.
If P1-01 = 3, the function is active when there is only one drive running on
the network.

Display Units for Sleep Level P2-02 when P2-01 is programmed for the
following:
P2-01 = 0: Display based on “Hz”
P2-01 = 1: Display based on “A”
P2-01 = 2: Display based on P1-02 Selection
P2-01 = 3: Display based on “rpm”
<0034>
P2-01 = 4: Display based on P6-02 Selection <0034>
Note: When P2-01 is set for a value of 2, display units will be dependent on
P1-02 setting. If P2-02 = 0, pump will sleep at minimum speed.
