Product Description:

The VT-HNC100-2-20-W-16-0-0 digital axis controller belongs to the VT-HNC Digital Axis Controllers series produced by Bosch Rexroth Indramat. Designed for hydraulic motion control, the unit supervises up to two closed-loop axes by generating precise command signals and evaluating sensor feedback in real time. In an automation cell, it replaces analog servo cards, allowing pumps, cylinders, or valves to reach programmed positions and velocities with repeatable accuracy. Mounted inside a machine cabinet, it coordinates press rams, mold-opening sequences, or synchronized gantry movements using proportional or servo-hydraulic hardware.

With an analog output resolution of 1.25 mV, the module drives valve electronics with reduced quantization error during pressure or flow adjustments. Incoming current loops are sampled at 5 µA, while voltage feedback is digitized at 5 mV to support accurate transducer evaluation. Encoder signals are processed up to 250 kHz, enabling high-speed position capture, and the internal CPU is a 16/32-bit MC68376 with a mathematical unit that executes axis algorithms without external hardware. Overall consumption stays at 8 W, which helps limit panel heat buildup. The controller manages two hydraulic loops, mounts on a wall plate, uses discrete wiring because it has no bus connection, and fits a 106.5 mm by 155 mm footprint suitable for compact electrical enclosures.

Cabinet layout is simplified by the controller depth of 204 mm, and stored parameters are retained in 1 MB of flash memory during power-off conditions. Machine signals terminate on a single terminal strip that provides 16 input/output points, so auxiliary limit switches or solenoids can be wired locally without extra interface boards. With a mass of 1.2 kg, the device places minimal load on mounting brackets during retrofits. The unit is supplied without an inductive position sensor, allowing the use of LVDTs or magnetostrictive probes as required for each hydraulic cylinder.
