Product Description:

The Bosch Rexroth Indramat VT-HNC100-1-2X-W-08-0-0-INK2 belongs to the VT-HNC Digital Axis Controllers series. It is a single-axis digital NC control dedicated to hydraulic positioning tasks in industrial automation. Mounted on a wall inside a control cabinet, the unit coordinates motion by reading voltage or current feedback, executing loop calculations on its 16/32-bit MC68376 processor, and driving proportional valves through its analog outputs. The hardware in this release is component series 2.

Physically, the controller measures 71 x 155 x 204 mm, allowing a narrow footprint next to pumps or drives. Its internal electronics draw only 8 W, so forced-air cooling is usually unnecessary. Program code and parameters are stored in 1 MB of flash, while dynamic variables reside in 256 KB of RAM, supporting fast task switching for hydraulic profiles. The analog voltage outputs resolve down to 1.25 mV, giving fine command granularity to servo valves, and the companion inputs are digitized at 5 mV per step for balanced command and feedback handling. Two current output channels, four voltage outputs, four voltage inputs, and eight digital inputs and outputs provide the electrical interface to transducers and actuators. Because the controller is supplied without an inductive position sensor, external LVDTs or magnetostrictive probes can be selected to fit the cylinder stroke.

For high-speed position feedback, the encoder interface accepts signals up to 250 kHz, which matches fast SSI or incremental encoders routed through the two counter channels. Setup and diagnostics pass through an RS232 (9.6 KBaud) port, simplifying direct connection when no fieldbus is present because this model is supplied without a bus connection. Voltage inputs digitize at 5 mV increments, which is suitable for pressure or displacement sensors that emit low-level signals. Despite its functionality, the housing weighs only 1.0 kg, minimizing panel strain during service or retrofit. The combination of compact dimensions, low power draw, and flexible I/O makes the controller suitable for hydraulic axes that require precise closed-loop positioning.
