ED1/ED2 Electro-proportional displacement control principle
Electro-proportional displacement control: With
pilot-pressure-related control, the pump displacement is adjusted
in proportion to the pilot pressure. Basic position without pilot
signal is Vg min, which includes the mechanically depressurized
basic position Vg min.
With increasing pilot pressure the pump swivels to a larger
displacement.
The necessary control power is taken from the operating pressure or
the external control pressure applied to port P. If the pump is to
be adjusted from the zero basic setting or from a low operating
pressure, port P must be supplied with an external control pressure
of at least 30 bar, maximum 50 bar.
