Product Description:

The VT-HNC100-1-2X-W-08-I-0-INK2 from Bosch Rexroth Indramat is a digital axis controller within the VT-HNC Digital Axis Controllers series. Designed for closed-loop positioning and force control on hydraulic machinery, this unit coordinates valve signals, sensor feedback, and network data to automate a single hydraulic axis. In industrial automation, the controller acts as the bridge between field-level transducers and higher-level PLCs, ensuring deterministic motion profiles and pressure regulation. The VT-HNC100-1-2X-W-08-I-0-INK2 is intended for wall mounting inside control cabinets where environmental shielding and short cable runs are required.

The unit belongs to component series 2 and uses the version for 1 hydraulic axis, so its scaling ranges and safety interlocks are tuned for a single-cylinder circuit. Fieldbus integration relies on InterBus S, enabling cyclic setpoint exchange with upstream controllers without additional gateway hardware. Analog acquisition is supported by four current channels and four voltage channels; the current paths are digitized at a resolution of 5 µA, while the voltage inputs use a 5 mV step size. Two current outputs generate proportional valve commands, and each voltage command uses a 1.25 mV step size. Processing is handled by the MC68376 microcontroller, backed by 1 MB of flash memory and 8 KB of EEPROM for parameter retention, while 256 KB of fast static RAM buffers runtime variables. A counter interface with two inputs is provided for incremental transducer evaluation when an inductive position sensor is not present.

The controller provides 8 freely assignable digital channels that support homing sensors, travel limits, or start commands. Its enclosure measures 71 x 155 x 204 mm and includes 4 voltage outputs for servo valves. The unit weighs 1.0 kg, which helps keep cabinet loading low.
