SYHNC-SEK-22A/M-24-0-C-E24-A035

The SYHNC-SEK-22A/M-24-0-C-E24-A035 axis controller is produced by Bosch Rexroth Indramat for the VT-HNC Digital Axis Controllers series. It supervises proportional valves, feedback sensors, and control logic for as many as two hydraulic cylinders in presses, molding stations, and other motion systems. By combining command processing, signal conversion, and error handling, the module provides closed-loop positioning for industrial automation applications. Its two-axis architecture supports hydraulic processes that require coordinated movement or separate motion sequences within the same machine.

The controller provides 4 analog differential inputs for connecting pressure and position transducers without external signal conditioning. Two analog V/I outputs and two analog voltage outputs generate drive currents or reference voltages for proportional valves. For discrete signals, the board includes 24 digital inputs and an equal number of digital outputs, allowing direct connections to limit switches, solenoids, and other field devices. It operates from a single 18 to 36 VDC supply, simplifying its connection to common industrial control power systems. The power section is enclosed in an HF-proof housing that shields the internal circuits from electromagnetic interference. Motion parameters are retained in nonvolatile EEPROM, while an error-code diagnostic output sends internal status information to the machine PLC. These interfaces allow the controller to process sensor feedback, issue valve commands, and exchange discrete operating signals without separate interface modules.

Parameter setup is performed through the Windows-based WIN-PED tool, which uploads and downloads parameter sets over a service interface. During operation, velocity is maintained through closed-loop speed control, while torque can be regulated in either an open or closed loop according to process requirements. The assembly can be stored at temperatures from -20 to +70 °C and contains two swivel sensor modules for feedback pickup. Its two-hydraulic-axis version can synchronize a pair of cylinders or manage two independent movements with common timing. The available control modes support applications that require consistent cylinder speed, controlled force, or coordinated positioning. Error reporting helps the connected PLC identify controller faults and respond through the machine’s existing logic.
