Product Description:

The VT-HNC100-2-3X-P-I-00-G02 is a digital axis controller manufactured by Bosch Rexroth Indramat and supplied in the VT-HNC Digital Axis Controllers series. As a closed-loop device for hydraulic motion, it executes position and velocity commands for two cylinders or motors in industrial automation equipment. It provides deterministic updates and controller-side signal conditioning without an additional fieldbus interface. It is suited to machines that require direct wiring for feedback and discrete control points.

This unit carries two analog processing channels arranged in 2 analog I/O slots; each slot is terminated on a connector that presents 15 analog connector pins for current or voltage feedback devices. Discrete signals are handled by 12 digital connector pins per plug, and the electronics accept 11 digital I/O per slot so machine states, limit switches, or interlocks can be wired directly. The logic backplane offers 2 digital I/O slots, permitting up to 22 simultaneous discrete points, and up to 20 of those can be assigned as outputs for valve solenoids or lamp stacks. The unit is configured for two hydraulic axes, so stroke and pressure loops for both cylinders are computed concurrently without polling delays.

The controller belongs to component series 3 in the product line. Motion feedback is received over two encoder ports, and each port has 15 contacts with a separate card cage that supports both incremental and SSI formats. Power to the internal logic is routed through 3 power connector pins, while host diagnostics can be retrieved through the serial interface that exposes 9 RS232 connector pins. Position sensing is selectable between quadrature or Incremental/SSI protocols, letting the user mix magnetostrictive and optical scales on one station. A dedicated timing circuit maintains 2-axis synchronization so both hydraulic actuators reach commanded targets within the same control cycle.
