When P9-08 = 0 and the output frequency rises above this level for
the time set in P9-11, the lead drive will request for a new lead drive
through the iQpump MEMOBUS / Modbus network.
When P9-08 = 2 and the output frequency rises above this level and
the delta feedback (setpoint - feedback) has exceeded the level set in
P9-10 for the time set in P9-11, the lead drive will request for a new
lead drive through the iQpump MEMOBUS / Modbus network.

system through the iQpump MEMOBUS / Modbus network.
When P9-12 = 2 and the output frequency drops below this level and
the delta feedback (feedback - setpoint) has exceeded the level set in
P9-14 for the time set in P9-15, the lead drive will request to be
removed from the system through the iQpump MEMOBUS / Modbus

High Feedback Quick De-stage
High FB De-stage
Determines the feedback level to trigger a quick de-stage, set as a
percentage of parameter P1-09. The quick de-stage ignores
parameters P9-12 to P9-15 and only uses an internal 2 s delay. A
setting of 0 disables the High FB De-stage feature.
