The H4U.app SC offers additional flexibility for the implementation of hydraulic control technology. Benefit from Bosch Rexroth's many years of extensive expertise in hydraulic control technology, while remaining within the familiar Siemens Ecosystem, without the need for additional control hardware. It is used for the control of hydraulic axis via valve-controlled and displacement-controlled drives.
Master command value principle, mean value principle, max value principle, minimum value principle, coast-down principle, mean value principle with alternating position/force control and minimum force limitation, mean value principle with alternating position/force control and constant sum force
Position control, velocity control, force control
The target integrator minimizes the variations of the target positions of individual axes when reaching the target position of the synchronized group in all modes of the synchronization controller.
H4U.app SC continuously determines and monitors the lag error based on the modeled and the measured actual position value. If the synchronized group can no longer follow the position command value, the H4U.app SC requests that the higher-level command value generator be stopped.
In case of command value generator stop, the break mechanismp provides the upstream command value generator with a brake acceleration in order to reach the velocity command value "0".
