Product Description:

The Bosch Rexroth Indramat VT-HNC100-1-2X-W-24-P-0-INK2 belongs to the VT-HNC Digital Axis Controllers series. It is a digital NC control that governs motion on a single hydraulic axis in presses, testing rigs, or metal-forming equipment where repeatable positioning and pressure regulation are needed. By combining bus communication, analog command channels, and discrete I/O inside one enclosure, the unit replaces traditional analog card stacks and allows deterministic position or pressure control from a higher-level PLC. This makes it suitable for mid-size machinery where closed-loop accuracy is required and control logic must coordinate valve behavior with machine sequencing.

Internally, the controller is configured for one hydraulic axis, so its closed-loop routines target valve-controlled cylinders rather than electric servos. Four analog voltage inputs and four analog voltage outputs provide ±10 V command and feedback channels for pressure or position transducers. These channels support direct interfacing with hydraulic valves and sensor signals used in feedback loops. Field communication takes place over the DP Profibus interface, with telegrams exchanged at up to 12 MBaud. A bank of 24 input/output terminals handles limit, enable, and alarm contacts without extra relays. Nonvolatile data reside in a 1 MB flash EPROM, the housing measures 106.5 × 155 × 204 mm, and a counter interface is present for incremental encoders.

Daily operation draws only 8 W, so the thermal load in the cabinet remains low. Motion parameters are processed in 256 KB of RAM, and diagnostics can be accessed through a RS232 (9.6 KBaud) port without taking the fieldbus offline. This arrangement allows status access while the main bus connection remains in place. The assembly weighs 1.2 kg, and its brackets support wall mounting to preserve panel depth. No inductive position sensor is included, so external LVDT or SSI hardware can be selected to match cylinder stroke.
