Product Description:

The VT-HNC100-1-30/S-I-30/000 is a digital axis controller manufactured by Bosch Rexroth Indramat and supplied under the VT-HNC Digital Axis Controllers series. Within the Digital NC control HNC100 platform, it supervises a single hydraulic axis and serves as the central NC unit inside a press or forming machine. The device interprets sensor feedback, drives proportional valves through voltage or current outputs, and coordinates axis positioning functions in industrial automation.

The control logic is executed by a 32-bit PowerPC that handles motion profiles and internal diagnostics. Two differential voltage input channels with a resistance of 200 kΩ ±5% capture command or feedback signals, and the signals are digitized with a resolution of 5 mV. Rotary encoders connect through an incremental interface that supports frequencies up to 250 kHz, enabling high-speed position capture. For ancillary functions, the board provides 11 configurable digital I/O points, and each digital output can source 20 mA. Analog instrumentation is powered by an integrated sensor rail limited to 200 mA, so external supplies are often unnecessary. Voltage outputs deliver ±10 mA into loads of 1 kΩ or higher, while the current channel can drive valves with loads as low as 500 Ω. The module is supplied without a bus connection, so all commands are processed locally.

The analog current output has a resolution of 0.625 µA, which supports precise valve metering. The voltage output has a step size of 1.25 mV for drives that accept voltage commands. An inductive position sensor is not installed, so an external LVDT or incremental encoder must provide position feedback. The IP20 housing protects against accidental contact with internal components but requires installation in a suitable control cabinet. The electronics package weighs 585 g, so it adds little mass to the panel and can be mounted directly on DIN rail hardware.
