Product Description:

The VT-HNC100-1-2X-M-24-0-C is a digital axis controller manufactured by Bosch Rexroth Indramat for the VT-HNC Digital Axis Controllers series. Classified in the HNC100 digital NC control series, it is supplied as an electronic module that supervises motion and force on one hydraulic axis in industrial machines. Installed in rack systems, the unit accepts machine-level setpoints and generates precise control signals so hydraulic cylinders track programmed positions or pressures where electronic drives are not practical.

Internally, the controller is the version for 1 hydraulic axis, and the unit is part of component series 2. A 32-bit MC68376 microcontroller executes the closed-loop algorithms while drawing only 8 W of power, which helps thermal management inside crowded cabinets. Program code and parameters reside in 1 MB Flash, 8 KB EEPROM, and 256 KB RAM, giving space for application-specific sequences and nonvolatile backups. For high-resolution feedback, the incremental or SSI encoder port handles frequencies up to 250 kHz, allowing rapid position updates during fast cylinder motion. Two voltage and two current analog outputs provide proportional valve commands, and the single controlled axis is referenced through the calibrated IW9 inductive sensor pair.

At the system boundary, the module accepts 4 voltage, 4 current, and 4 impedance analog inputs for transducers such as pressure sensors, and it exposes 24 input/output digital channels for limit switches, solenoid coils, or status bits. A ±10 V reference voltage standardizes the command range, ensuring consistent scaling between the controller and higher-level PLCs. The mechanical size is 106.5 × 155 × 204 mm, and the card weighs 1.2 kg, which simplifies layout calculations for vibration-sensitive racks. Communication relies on a local RS232 serial interface rather than a fieldbus connection, so wiring remains point-to-point between the controller and the supervisory computer.
