Product Description:

The VT-HNC100-1-2X-W-08-0-E is a digital axis controller manufactured by Bosch Rexroth Indramat for the VT-HNC Digital Axis Controllers series. It is supplied as a version for one hydraulic axis and fits into the wider Digital NC control HNC100 platform used to synchronize hydraulic motion with electrically driven equipment. Installed beside a proportional or servo valve, the unit converts encoder and sensor feedback into command signals that keep position, speed, and pressure within the tolerances demanded by presses, test rigs, or multi-axis CNC machinery.

This model is tailored for a single hydraulic channel, so processing resources are not divided between multiple loops. Configuration over RS-232 is mandatory because the unit is shipped without a bus connection, and the port communicates at 9.6 KBaud. The unit provides 8 Input / Output terminals for limit switches, interlocks, or status flags. Analog accuracy is supported by a current input resolution of 5 µA, a voltage input resolution of 5 mV, and a voltage output resolution of 1.25 mV, allowing precise valve staging. Position feedback from incremental or absolute transducers can be sampled at up to 250 kHz, keeping closed-loop bandwidth high. Control tasks are executed by an MC68376 microprocessor, and application parameters are retained in 8 KB of EEPROM so settings survive power cycling.

The unit draws only 8 W, keeping cabinet thermal loads low while the 32-bit CPU uses 1 MB of flash memory and 256 KB of RAM for real-time variables. Component series 2 identifies the hardware revision, and wall mounting simplifies installation inside a control panel. The housing measures 71 × 155 × 204 mm, so it occupies little space next to servo drives, and the enclosure weight is 1.0 kg, which reduces handling effort during installation.
