General Product Overview
The VT‑HNC100‑1‑2X/W‑08‑0‑0 is a compact programmable NC‑style motion controller dedicated for single electro‑hydraulic axis closed‑loop regulation. It executes position, velocity, pressure and force control for hydraulic actuators, supporting incremental / SSI absolute encoder feedback and valve drive output for proportional hydraulic valves. This 2X‑series variant adopts wall‑mount housing design and integrates 8‑channel digital I/O, without onboard fieldbus interface. It runs Rexroth NC‑style motion sequence programs, delivers comprehensive axis monitoring, following‑error alarm and travel‑limit supervision. Widely deployed in presses, injection‑molding machines and special‑purpose hydraulic machinery; original manufacturing has been discontinued, used for spare‑part replacement of existing installed‑base equipment.
