Control devices
HD – Proportional control hydraulic
The proportional hydraulic control provides infinite setting of the
displacement, proportional to the pilot pressure applied to port X.
Beginning of control at Vg max (maximum torque, minimum speed at
minimum pilot pressure)
End of control at Vg min (minimum torque, maximum permissible speed
at maximum pilot pressure)
EP – Proportional control electric
The proportional electric control provides infinite setting of the
displacement, proportional to the control current applied to the
solenoid (sizes 28 to 200) or proportional valve (sizes 250).
For size 250, the pilot oil supply at port P requires an external
pressure of pmin = 30 bar (pmax = 100 bar).
Beginning of control at Vg max (maximum torque, minimumspeed at
minimum control current)
End of control at Vg min (minimum torque, maximum permissible speed
at maximum control current)

Features
––Variable plug-in motor with axial tapered piston rotary group of
bent-axis design, for hydrostatic drives in open and closed
circuits.
––Far-reaching integration in mechanical gearbox due to a recessed
mounting flange located on the center of the case (extremely
space-saving construction).
––Easy to install, simply plug into the mechanical gearbox (no
configuration specifications to be observed).
––Tested unit ready to install.
––For use especially in mobile applications.
––The displacement can be infinitely changed from Vg max to Vg min
= 0.
––The wide control range enables the variable motor to satisfy the
requirement for high speed and high torque.
––The output speed is dependent on the flow of the pump and the
displacement of the motor.
––The output torque increases with the pressure differential
between the high-pressure and low-pressure side and with in
