Product Brand & Model Title
Official Product Name: VT‑HNC100 Single‑Axis Programmable Electro‑Hydraulic Digital Axis Controller Brand: Bosch Rexroth (Indramat) Model No: VT‑HNC100‑1‑23W‑08‑P‑0 Material Number: R900959001Indramat U… Product Grade: Legacy wall‑mount NC‑type hydraulic motion controller with PROFIBUS‑DP interface; original production discontinued, available as spare‑part stock for existing installed‑base machineryGK-DCS
General Product Overview
The VT‑HNC100‑1‑23W‑08‑P‑0 is a programmable single‑axis digital controller dedicated for electro‑hydraulic closed‑loop regulation. It executes position, velocity, pressure and force control for hydraulic actuators, supporting TTL incremental encoders and SSI absolute position transducers for position feedback, and provides analog output to drive proportional hydraulic valves. This 23‑series variant adopts wall‑mount housing, integrates 8 configurable digital I/O channels, and is equipped with native PROFIBUS‑DP fieldbus interface for PLC / DCS higher‑level system interconnection. It supports standalone NC‑motion sequence programming, comprehensive axis monitoring, following‑error alarm and travel‑limit supervision. Widely deployed on hydraulic presses, forming machines and special‑purpose hydraulic equipment; used for spare‑part replacement and retrofit of legacy hydraulic machineryGK-DCS.
