TwinCAT PLC Hydraulic Positioning

The blocks and functions of this library can be used for positioning and controlling hydraulic axes. Various functions are available for the conversion of sensor signals into actual positions and of control outputs into output data.

Blocks for point-to-point movements are supplied. These blocks operate with time or path-controlled ramps. Optionally, constant or cosine acceleration can be used. In two variants, breaking is optimised by a root calculator or by an adaptive time control. Dead path and dead time compensation are available for the transition to the target position. The behaviour at the target can be selected through parameterisation: position control, pressure output with the correct sign, automatic repositioning.

The motion can be influenced through monitoring functions and aborted prematurely if a limit value is reached. Alternatively, a motion can be slowed down, for example, through a pressure controller.

Apart from the remanence and persistence options of the TwinCAT PLC run-time, axis parameters can also be stored and loaded as files via supplied blocks. The modular configuration of the axis within the PLC application enables the flexible combination of library blocks with customer- and application-specific special functions.
