Cylindersynchronous control
HCB-CSC (Cylinder Synchronous Control)

The cylinder position and synchronization controller regulates up to 20 cylinders in synchronization.

The cylinders are moved in the direction of the specified target position. A braking characteristic reduces the speed depending on the distance to the target position, thus ensuring a smooth stop.

The standard hardware for this control system is the HCB controller, which can be used to control 4 solenoids (two 4/3-way valves). If the CSC control unit is to control more than 2 cylinders in synchronization, several control units are networked via CAN bus. The operating modes “Analog”, in which a variable set value is controlled, and “Digital”, in which adjustable fixed values are controlled, are available. The positions are approached via adjustable ramps. The maximum speed at which the system moves into position can be set via an analog value.

Another method of positioning more than 2 cylinders per controller in synchronization is to port the function to another hardware platform. The same applies to the interaction of the CSC software with other Völkel standard control systems or the integration of the functionality into a Völkel machine control system.

installation, it is possible to have the cylinders move with different offsets to each other. The advantage over purely hydraulic control is the variability of the control.

The synchronization controller is used as part of an electronic track rod (special control with offset dependent on steering angle), when lifting platforms, in material feed with cascaded pushers, etc.

Inputs and outputs

• Digital inputs for mode switching, for fixed values, manual operation. Can be parameterized as release for position control with fixed position difference between cylinder 1 and 2, release for fine adjustment of the target position, etc.
• Analog inputs for position and speed set values, speed in manual mode, fine adjustment of target position, actual position of cylinders 1 and 2
• Proportional outputs with current feedback measurement for 2 cylinders
• Status outputs, for displaying input/output errors, position errors, in position, limitation on/off active
• CAN interface for communication between the axles
