Position controller
HCB-PCB (Position Control Basic)

The position controller for a cylinder is suitable for simple positioning tasks in hydraulics. It accelerates a hydraulic cylinder towards a target position and holds it within an adjustable target window once it has been reached.

The standard hardware for this control system is the HCB controller, which can be used to control 2 solenoids. The PCB control unit thus enables the positioning of a cylinder by means of a 4/3-way valve. The operating modes “Analog”, in which a variable set value is controlled, and “Digital”, in which adjustable fixed values are controlled, are available. The controller function is defined by means of parameterization.

If the position controller needs to be integrated into a machine control system, it can easily be ported to another Völkel hardware platform. For example, several position controllers can level a vehicle support or interact with other control parts.

Possible applications are, for example, height control of a field sprayer, the return of a wheel loader bucket to its starting position (return to dig), etc.

Inputs and outputs

• Digital inputs, parameterizable for release, for manual raising and lowering or with up to 4 fixed values.
• Analog inputs for position setpoint and actual position value (4-20mA or 0-10V)
• Proportional outputs with current feedback measurement (extend and retract cylinders)
• Status output for error messages or “In position”
