■ If P2-01 = “3: Output Speed (rpm)”
<0034>
The iQpump drive can be configured to enter a “sleep” condition based on the feedback signal. The drive will enter the sleep mode when
the feedback signal rises above the programmed Sleep Level (P2-02) for a time specified by the Sleep Delay Time (P2-03).
■
If P2-01 = “4: Low Flow (Terminal A1 - Flow meter required)”
<0034>
The iQpump drive can be configured to enter a “sleep” condition based on the feedback signal. The drive will enter the sleep mode when
the feedback signal rises above the programmed Sleep Level (P2-02) for a time specified by the Sleep Delay Time (P2-03).
