Tab. 7-18: Parameter list of pump power limitation
Pump power limitation function can be activated via bit0 of F4.03.
The real-time pump power can be calculated from pressure feedback, the actual
speed and pump displacement. If the calculated pump power output exceeds
the pump power limitation [F4.35] then the speed will be reduced to keep the
pump power output within the limit.
In pump power limitation function pump displacement "Effective Pump Vg"
(F4.38) will be used for the calculation, for application with constant pump dis-
placement F4.38 = F4.30, for application with 2 point pump or double pump,
F4.38 will be calculated with F4.30 and F4.31 according to pump switching log-
ic.
