Product Description:

The VT-HNC100-2-2X-M-16-0-0 is a digital axis controller from Bosch Rexroth Indramat, positioned within the VT-HNC digital axis controllers series and the broader Digital NC control HNC100 product series. Designed for closed-loop coordination of hydraulic motion, the unit executes numeric commands and issues proportional signals to valves or pumps. Inside an automation cell it links a PLC to two hydraulic cylinders, translating program targets into precise current and voltage profiles.

Its hardware variant is the version for 2 hydraulic axes, matching equipment that requires synchronized cylinder positioning. The controller belongs to component series 2 and is intended for rack installation, so it slides into HNC100 backplanes without additional brackets. Four current input channels accept ±10 mA set-points, and the unit samples them with a resolution of 5 µA for fine tracking of analog transducers. Complementing these are four voltage input channels digitized at 5 mV steps. Sixteen bidirectional digital terminals support limit switches and status flags on this two-axis model. Actuation signals leave the board through two current output stages, while reference rails of ±10 V ±25 mV maintain calibration. The controller processes incremental encoder feedback up to 250 kHz, delivering tight loop closure on fast hydraulic slides. Operation is stand-alone because it is supplied without a bus connection.

The controller also handles absolute encoders; its synchronous serial interface accepts data words up to 28 bits, so high-resolution position information is preserved. For voltage-driven actuators the four analog outputs step in 1.25 mV increments, producing smooth proportional valve movements. Power demand stays at 8 W, reducing cabinet heat load, and the assembled board weighs only 1.2 kg, easing maintenance swaps. Two current output channels already described align with four voltage outputs to support hybrid drive layouts. Sensor options remain flexible because the card ships without an inductive position sensor, and diagnostic routines supervise over-range conditions on the sixteen digital lines.
