This hydraulic control unit precisely controls and synchronizes two axes and offers a PROFINET interface. It combines robust position control functions with flexible synchronization modes and supports both analog and SSI sensors.
The POS-124-U-PFN hydraulic control unit is designed to control two hydraulic positioning axes that can operate either independently or in synchronized mode.
The unit is designed for installation within a shielded EMC enclosure (control cabinet) and mounts onto a standard DIN rail. It has an IP20 protection rating.
The two axes are controlled via analog outputs (+/-10 V or 4–20 mA). Feedback can be provided by either analog displacement sensors (0–10 V or 4–20 mA) or digital SSI sensors. The setpoint is specified via the Profinet interface.
Key parameters include VMODE (defining the type of position control) and SYNCMODE (defining the type of synchronization). SYNCWIN defines the tolerance for synchronization errors. Braking distances (D:A/D:B) or loop gain (V0) determine the dynamic behavior of each axis.
Parameterization is performed via PC using WPC software - either through the integrated USB interface or, alternatively, via the Profinet interface.
A special feature of the POS-124-U-PFN is its PT1 synchronization controller.
