Product Description:

The VT-HNC100-1-2X-W-08-S-0-ENDA is a digital axis controller produced by Bosch Rexroth Indramat within the VT-HNC Digital Axis Controllers series. It supervises hydraulic servo-driven machinery by processing numerical commands and driving valves so a single actuator moves to precise positions and forces. Used inside presses, die-casting cells, or plastic-molding equipment, the module provides closed-loop motion control and industrial networking capabilities that replace discrete analog cards with one integrated platform.

Internally, the controller is configured for 1 hydraulic axis, so its control logic and feedback loops expect a single linear or rotary cylinder. Sensor and actuator signals are routed through eight analog channels: there are 4 analog current inputs with a 100 Ω ±0.2% shunt suited to ±20 mA transducers, and 4 analog voltage inputs that present 200 kΩ ±2% impedance to minimize loading. Current measurement has a 5 µA resolution, while voltage sampling is specified at 5 mV. Two configurable current outputs modulate proportional valves, and four voltage outputs can reference valve electronics or pressure transducers. For on/off logic, the board provides 8 digital I/O channels, allowing interlocks or limit switches to be read without external relays.

Communication and processing resources support complex motion sequences. The integrated SERCOS interface exchanges real-time setpoints with higher-level PLCs, while the 16/32-bit MC68376 microcontroller executes position and pressure algorithms at deterministic cycle times. Program code and axis parameters reside in 1 MB of Flash EPROM, ensuring retention during power loss. A built-in EnDat interface plus a 1 Vss sinusoidal channel accepts high-resolution encoders, while an inductive position sensor is not included. The enclosure measures 71 × 155 × 204 mm and weighs 1.0 kg, so it can be mounted on a cabinet wall. The unit belongs to component series 2 in the HNC100 product line.
