◆ PI Feedback via Network
The Network PI Feedback comes from an iQpump drive on the network with a valid analog PI feedback source and can be used as the primary or
secondary feedback source for a networked iQpump drive.
• Set P9-02 to 0 if an iQpump drive has an analog PI feedback device installed and switching to network as a back-up is not desired.
• if an iQpump drive has an analog PI feedback device installed and the network PI feedback is considered as a back-up, set P9-02 to 1 for no alarm
message when switched and set P9-02 to 2 for an alarm.
• Set P9-02 to 3 if an iQpump drive has no analog PI feedback device installed and relies solely on the analog PI feedback of another networked
iQpump drive.
Note: Connect an analog PI feedback device to each iQpump drive for best performance.

Drive is in Auto Mode and waiting for a run
command from the iQpump Memobus network.
Drive is in Auto Mode, Lead operation and is
currently regulating the system using PI control.
Drive is in Auto Mode, Lag operation and is
holding the speed at the time it made the switch
from being a lead drive to a lag. Speed is held
until P9-07 time expires. U1-01 will display
Frequency instead of System Units.
