Product Description:

The VT-HNC100-1-2X-W-24-0-D belongs to the VT-HNC Digital Axis Controllers series from Bosch Rexroth Indramat. It is a digital NC control for hydraulic motion and is supplied as a version for 1 hydraulic axis, so one closed-loop axis can be regulated in presses, injection-molding machines, or test rigs. The hardware is delivered without a bus connection, so external fieldbus hardware can be selected as needed. Wall-mount construction lets the unit fit directly into cabinet layouts for factory automation. This makes it suitable for applications that need precise cylinder positioning and repeatable hydraulic control.

Its computational core is a 16/32-bit MC68376 microcontroller that manages proportional valves and feedback loops in real time. Program code and parameters are stored in 1 MB of Flash EPROM, while dynamic data resides in 256 KB of battery-buffered RAM for axis-tuning tables and diagnostic records. This memory arrangement supports local parameter storage and responsive control during operation. The device draws only 8 W, which keeps heat dissipation modest inside the panel. It also provides 24 digital inputs and outputs for limit switches, interlocks, and status signals. That I/O count supports machine permissives, sensor states, and ready signals without extra interface hardware. The housing measures 155 mm high, 106.5 mm wide, and 204 mm deep, and it weighs 1.2 kg for simple wall installation.

Position evaluation works with incremental encoders up to 250 kHz and with SSI sensors using data words up to 28 bits. Incoming voltage references are resolved to 5 mV at the analog converter. Corresponding analog outputs are generated with a granularity of 1.25 mV, which supports stable command values for servo valves. The controller also supports direct connection of calibrated HR1000 and HR2000 inductive probes for absolute sensing. These feedback options let the unit work with both relative and absolute position sources in hydraulic axes.
