Product Description:

The VT-HNC100-2-2X-W-16-Z-0 digital axis controller is manufactured by Bosch Rexroth Indramat and belongs to the VT-HNC Digital Axis Controllers series. Within the wider HNC100 digital NC control series, this module executes closed-loop control for hydraulic cylinders and valves, translating motion commands from an automation host into precisely timed flow and pressure signals. By integrating measurement, computation, and drive command generation inside a compact wall-mounted housing, it reduces panel wiring and shortens response times in presses, forming machines, and general test benches.

The controller is supplied as a version for 2 hydraulic axes, and each axis can be monitored with 4 analog input channels that accept voltage or current signals. A current feedback path uses an input resistance of 100 Ω, while voltage feedback uses a 200 kΩ impedance and 5 mV resolution for accurate transducer scaling. Command generation benefits from 16 digital input / output lines that capture limit switches or trigger auxiliary functions, plus 2 current and 4 voltage output channels that drive servo amplifiers directly. The on-board 1 MB Flash EPROM stores parameter sets and application code so updates survive a power cycle. Component series 2 hardware is built around the 32-bit arithmetic of a 16/32-bit MC68376 processor, and the absence of an inductive position sensor interface simplifies wiring when LVDT transducers are not required.

The module draws 8 W of power, allowing convection cooling, and the 16/32-bit MC68376 CPU maintains deterministic cycle times under that load. The aluminum enclosure measures 204 mm deep, 155 mm high, and 106.5 mm wide, yet weighs only 1.2 kg, easing installation on crowded backplates. Wall mounting slots are pre-machined, and the depth clearance helps protect field wiring routed underneath. The aluminum housing also provides a rigid structure in applications where nearby hydraulic equipment can transmit vibration to surrounding electronics.
