0: Fixed Speed
2: Turn Off
3: Follow Lead Spd
Determines the functionality of the lag drives.
0: Fixed speed. The drive runs at the P9-06 setting after the time
set in P9-07 expires.
2: Turn off. The drive stops running when it switches to a lag
drive after the time set in P9-07 expires.
3: Follow Lead Speed. The drive will follow the speed of the
current lead drive, applying P9-30 gain and P9-31 bias.
Default: 0
Range: 0, 2, 3

Lag Fixed Speed Lag Fixed Speed
Sets the speed at which the drive will run when the drive changes
from a lead to a lag and the time set in P9-07 has expired.

(0DFC)
Add Frequency Level Add Freq Lvl
When P9-08 is set to 0, this parameter sets the level above which
the output frequency needs to rise for the time set in P9-11 before
the lead drive will send a request for a new lead drive via the
iQPump MEMOBUS network.
When P9-08 is set to 2 and the delta feedback (setpoint minus
feedback) has exceeded the level set in P9-10 for the time set in
P9-11, this parameter sets the level above which the output
frequency needs to rise before the lead drive will send a request
for a new lead drive via the iQPump MEMOBUS network.
Default: 59.5 Hz
Min.: 0.0
Max.: 400.0

(0DFD)
Add Delta Level Add Delta Lvl
When P9-08 is set to 1, this parameter sets the level above which
the delta feedback (setpoint minus feedback) must rise for the
time set in P9-11 before the lead drive will send a request for a
new lead drive via the iQPump MEMOBUS network.
When P9-08 is set to 2 and the output frequency has exceeded
the level set in P9-09 for the time set in P9-11, this parameter
sets the level above which the delta feedback (setpoint minus
feedback) needs to rise before the lead drive will send a request
for a new lead drive via the iQPump MEMOBUS network.
Default: 0.0 PSI

Remove Freq Lvl
When P9-12 is set to 0, this parameter sets the level below which
the output frequency must fall for the time set in P9-15 before
the lead drive will send a request to be removed from the system
via the iQPump MEMOBUS network.
When P9-12 is set to 2 and the delta feedback (feedback minus
setpoint) has exceeded the level set in P9-14 for the time set in
P9-15, this parameter sets the level below which the output
frequency must fall before the lead drive will request to be
removed from the system via the iQPump MEMOBUS network.
