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.
