Product Description:

The VT-HNC100-1-2X-M-24-0-0 is a rack-installable digital axis controller produced by Bosch Rexroth Indramat for the VT-HNC Digital Axis Controllers series. It is a Series 2 unit configured for one hydraulic axis, so it supervises cylinder position and force by combining valve commands with feedback data. In an automation cell, the device serves as the numerical control layer between a machine’s hydraulic drive and the higher-level programmable logic controller. This arrangement allows the controller to process sensor feedback and issue valve commands fast enough for stable hydraulic motion.

The controller’s analog front end provides 4 differential input channels for pressure or position transducers, while two regulated current outputs and four voltage outputs drive proportional valves that modulate flow. Machine states and interlocks are exchanged through 24 input/output points, allowing direct wiring of limit switches, enable contacts, or status lamps without extra interface relays. Internal electronics draw only 8 W, which keeps the load on cabinet power supplies low and helps reduce heat buildup in crowded racks. Motion algorithms run on a MC68376 (16/32-bit) microcontroller with integrated timers and DSP-type instructions suited to real-time position loops. Program code and parameter sets reside in 1 MB of nonvolatile flash memory, so control data remains stored when the unit is powered down.

The enclosure measures 106.5 x 155 x 204 mm, which provides front-panel space for terminal blocks while maintaining a compact footprint beside pumps, drives, and safety modules. Volatile workspace is limited to 256 KB of RAM, which is sufficient for trajectory buffers and diagnostic logs created during operation. A front-mounted RS232 (9.6 kbaud) port supports simple point-to-point communication and data backup without requiring a fieldbus connection. The unit’s steel housing and internal card assembly weigh only 1.2 kg, which reduces mechanical load on the rack guides during handling. Its compact form also helps it fit into mixed-control cabinets where hydraulic, electrical, and safety hardware must share limited space.
