Product Description:

The VT-HNC100-3-3X-N-I-00-000 axis controller is produced by Bosch Rexroth Indramat within the VT-HNC Digital Axis Controllers series. It belongs to the Digital NC control HNC100 product group and serves as the electronic command center for hydraulic drives, translating numerical motion profiles into valve currents and monitoring feedback signals in real time. Intended for cabinet installation, the module enables multi-axis synchronization so industrial machines can execute position, velocity, and pressure tasks with repeatable accuracy while maintaining compact dimensions suitable for standard DIN rails and cabinets with limited heat dissipation.

The controller is supplied as a version for 3 hydraulic axes, matching installations that need simultaneous regulation of three cylinders. Because it is delivered without a bus connection, all real-time exchange occurs through a dedicated Ethernet channel that moves 992 bytes of cyclic I/O during each scan. A 32-bit PowerPC processor executes closed-loop code with a minimum cycle time of 2 ms, keeping valve commands coherent with sensor feedback. Every channel provides 11 digital I/O points per axis for limit sensing or safety interlocks, and incremental encoder pulses can be evaluated up to 250 kHz to support fine positional resolution. The hardware designation indicates component series 3, and an SSI port completes the control interfaces.

A 5.25 V encoder supply is provided, and the analog interface offers a +10 V reference for proportional valves. Communication runs at 100 Mbit/s, while absolute position words are 28-bit wide on the SSI channel, which uses an RS485 physical layer. The IP20 housing is 120 mm high and 105 mm wide, allowing installation in shallow cabinets. Because no inductive position sensor is integrated, external LVDT devices can be added when required.
