Product Description:

The VT-HNC100-1-2X-W-08-0-0 is a digital axis controller manufactured by Bosch Rexroth Indramat for the VT-HNC Digital Axis Controllers series. It is configured for one hydraulic axis and supplies closed-loop control signals that coordinate position and pressure in presses, test stands, and forming equipment. By integrating set-point generation, servo control, and diagnostics, the unit streamlines automation panels that would otherwise require separate valve drivers, counter cards, and PLC logic. It is suited to hydraulic applications that need repeatable axis motion together with pressure-based process control.

From a hardware standpoint, the controller provides 8 digital I/O points that can link directly to limit switches, pump interlocks, or alarm relays. The feedback stage processes incremental encoder signals up to 250 kHz, maintaining count integrity on fast linear scales. Control algorithms execute on a 16/32-bit MC68376 microcontroller, allowing floating-point calculations for hydraulic tuning while keeping power draw to just 8 W. The aluminum housing is sized at 71 × 155 × 204 mm and attaches to a back panel by wall-mounting brackets. This version carries no fieldbus card and can drive 500 Ω current loads or 1 kΩ voltage loads. It also operates without an inductive position sensor, so axis referencing relies on the connected external transducer. These interfaces support direct connection to the switches, relays, and feedback devices commonly used in hydraulic control systems.

Installation is eased by a shipping mass of 1.0 kg, which keeps panel handling straightforward during assembly. All analog command and feedback channels center on a symmetrical ±10 V reference, so common servo valves and pressure transducers connect without level shifting. The input amplifiers present 200 kΩ ±2 % of resistance, minimizing loading on upstream controller outputs. Parameter files, oscilloscope traces, and diagnostic messages are transferred through the front-panel serial port at 9.6 KBaud. As a component in series 2, the unit shares parameter structures with other 2X releases, which helps maintain consistent operation across multiple hydraulic axes.
