The position controller for one cylinder is suitable for simple positioning tasks in the hydraulics. It accelerates a hydraulic cylinder in the direction of a target position and keeps it within an adjustable target window after reaching it.

The standard ECU for this controller is the HCB controller, which can be used to control 2 solenoids. The PCB controller thus enables the positioning of a cylinder by means of a 4/3-way valve. The operating modes “Analog” and “Digital” are available, through which an analog setpoint and selctable digital fixed values can be controlled. The control function is defined by means of parameterization.

If it is required to integrate the position controller into a machine control system, the porting to another Völkel hardware platform is easily possible. For example, several position controllers can level a vehicle support or interact with other control components.

Possible applications are e.g. height control of a machine, return of a wheel loader shovel to its starting position (return to dig) etc.

Inputs and outputs

• Digital inputs, parameterizable for release, for manual lifting and lowering or with up to 4 fixed values
• Analog inputs for set value position and actual position value (4-20mA or 0-10V)
• Proportional outputs with current feedback measurement (cylinder extension and retraction)
• Status output for error messages or “In position”
