DR - Pressure control
The pressure control limits the maximum pressure at the pump
output within the pump control range. The variable pump only
supplies as much hydraulic fluid as is required by the consumers.
If the operating pressure exceeds the pressure setpoint set
at the integrated pressure valve, the pump will adjust towards a
smaller displacement and the control deviation will be reduced.
The pressure can be set steplessly at the control valve.
DG - Two-point control, directly operated
The variable pump can be set to a minimum swivel angle by
connecting an external control pressure to port X.
This will supply control fluid directly to the stroke piston; a
minimum control pressure of pst ≥ 50 bar is required.
The variable pump can only be switched between
Vg max or Vg min.
Please note, that the required control pressure at port X is
directly dependent on the actual operating pressure pB in
port B. (See control pressure characteristic).
Control pressure pst in X = 0 bar Vg max
Control pressure pst in X ≥ 50 bar Vg min
