Add Freq Level
Add Freq Lvl
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 Network.
When P9-08 = 2 and the output frequency rises above this level 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 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 network.
