Der Volumen-, Druck-, Leistungsregler regelt je nach Parametrierung auf einen Volumen-, Druck-, oder Leistungssollwert der Hydraulik.
According to the parameterization, this controller regulates the volume, pressure or power of the hydraulics according to the setpoint.
According to the parameterization, this controller regulates the volume, pressure or power of the hydraulics according to the setpoint. The control characteristic can be freely parameterized. In addition it is possible to switch between different control characteristics dependent on the application or dynamically adjust the amplication factor depending on the magnitude and sign of the regulation deviation. To prevent the hydraulic system from reacting too aggressively setpoint jumps can be limited by freely adjustable ramps.
If the controller is set as a power regulator, the power reserve of the engine can be calculated from its torque and speed and taken into account. For this purpose, the torque characteristic curve of a diesel engine is parameterized tabularly while the speed is measured. Alternatively, for electric motors, it is possible to parameterize the drive power via fixed values for torque and speed.
The standard ECU for the VPP is the HCB controller. The VPP supports the operation of a tandem pump. If it is integrated into a machine controller, it can easily be ported to another Völkel hardware platform. The volume, pressure and power controller is used, for example, in bow thrusters, in the power control of spray pumps and screw conveyors.
