Product Description:

The VT-HNC100-2-3X-N-I-00-000 is a digital axis controller manufactured by Bosch Rexroth Indramat as part of the VT-HNC Digital Axis Controllers series. It belongs to the Digital NC control HNC100 product family and is intended to regulate hydraulic drives directly from a PLC or industrial PC. By processing setpoint data and feedback in real time, the unit governs valve currents and monitors axis status, providing deterministic motion control for press, molding, or metal-forming machines that rely on hydraulic power transmission. It can therefore manage command handling and feedback evaluation in one compact control platform for hydraulic motion applications.

This card is the version for 2 hydraulic axes and is identified as component series 3. It operates without a bus extension, yet it appears on an Ethernet network as a PROFINET IO RT device that exchanges up to 100 Mbit/s full-duplex. Conformance Class A ensures basic RT communication, while a protection rating of IP20 limits installation to enclosed panels. Closed-loop computations execute every 2 ms, and the controller can forward a cyclic process image of 992 bytes to the supervisory controller during each scan. This arrangement allows the unit to share network infrastructure with other automation devices while maintaining real-time communication for axis control. No synchronization option is provided, and an inductive position sensor is not fitted, so external interfaces must supply any master clock or direct transducer data required by the application.

Per slot, the module offers 11 digital I/O points per slot, from which as many as 20 digital outputs can be mapped for valves, relays, or status lamps. Each slot also carries two analog current inputs, one analog current output, two analog voltage outputs, and 2 analog voltage inputs per slot, allowing simultaneous acquisition of pressure or position signals and command of proportional valves. That mix of signal types supports hydraulic axes that require both continuous feedback monitoring and direct valve actuation from the same controller. When installed as a PROFINET IO RT device, the controller publishes its I/O image within the PROFINET frame, so deterministic axis data travel alongside general machine traffic without a separate fieldbus.
