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 only pump displacement Vg1 (F4.30) will be
used for the calculation, Vg2 (F4.31) will not, so for double pump application
please only consider the main pump for pump power F4.35.
