Bosch Rexroth VT-HNC100 Series Technical Notes

The Bosch Rexroth VT-HNC100 series represents a dedicated line of digital axis controllers engineered for high-precision hydraulic motion control in heavy industrial environments. Deployed extensively across chemical processing plants, nuclear power facilities, steel mills, offshore platforms, and petroleum refineries, the VT-HNC100 platform provides closed-loop position, velocity, and force control for electrohydraulic servo and proportional valve systems. Its compact Euro-card form factor and standardized EURO rack mounting make it a long-term fixture in control cabinets where replacement cycles span decades. The series is fully compatible with Rexroth proportional valves (4WRPH, 4WRKE, 4WRPEH families) and servo valves (4WSE, 4WS2EM families), making it a universal interface layer between PLC/DCS command systems and hydraulic actuators in safety-critical processes.

VT-HNC100 Full Catalog & Functionalities (SKU List)

The following SKUs represent verified, commonly deployed modules within the Bosch Rexroth VT-HNC100 digital axis controller family. Each unit is a single-axis controller occupying one Euro-card slot:

VT-HNC100.C-30/P-S-00/000: Single-axis digital controller, PROFIBUS-DP, standard I/O, 30V supply rail, base configuration — the subject unit of this listing.
VT-HNC100.C-08/P-S-00/000: Single-axis controller, PROFIBUS-DP, 8A valve output current rating, standard I/O configuration.
VT-HNC100.C-30/P-S-00/001: Variant /001 — extended parameter set with additional ramp function generator options.
VT-HNC100.C-30/P-S-00/002: Variant /002 — modified enable logic for safety relay integration in SIL-rated circuits.
VT-HNC100.C-30/0-S-00/000: Non-PROFIBUS variant; RS-232 commissioning only, no fieldbus slave capability.
VT-HNC100.C-08/0-S-00/000: RS-232 only, 8A output, standard I/O — common in legacy standalone hydraulic press control.
VT-HNC100.C-30/P-S-01/000: Extended I/O variant; additional analog input channel for external position transducer (SSI or analog ±10V).
VT-HNC100.C-30/P-S-02/000: Dual-transducer input variant for redundant position feedback in nuclear and offshore applications.
VT-HNC100.C-30/P-S-00/010: Factory-configured for servo valve drive; higher current resolution, tighter deadband compensation.
VT-HNC100.C-08/P-S-00/010: Servo valve variant, 8A output, PROFIBUS-DP — used with 4WSE2EM servo valves in rolling mill applications.
VT-HNC100.C-30/P-S-03/000: Extended diagnostics variant; onboard fault logging to EEPROM, retrievable via RS-232.
VT-HNC100.C-30/P-S-00/020: High-speed variant; 2 kHz control loop execution for fast-response injection molding hydraulics.
VT-HNC100.C-30/P-S-04/000: Pressure/force control primary mode; position control secondary — for forging press force regulation.
VT-HNC100.C-30/P-S-05/000: Synchronization variant; electronic gearing function for multi-axis hydraulic synchronization without master PLC.
VT-HNC100.C-30/P-S-06/000: CANopen slave variant — alternative fieldbus for mobile hydraulics and non-PROFIBUS plant architectures.
VT-HNC100.C-30/P-S-07/000: DeviceNet slave variant — deployed in North American automotive stamping lines with Allen-Bradley PLC infrastructure.
VT-HNC100.C-30/P-S-08/000: Ethernet/IP variant — later-generation fieldbus option for integration with Rockwell ControlLogix systems.
