Product Description:

The Bosch Rexroth Indramat VT-HNC100-3-3X-E-I-00-000 is a digital axis controller in the VT-HNC Digital Axis Controllers series. It belongs to the HNC100 product line and is intended for closed-loop positioning and velocity regulation of hydraulic cylinders in multi-axis machinery. By combining analog interfaces with high-speed digital communication, the module coordinates motion sequences so presses, test rigs, and injection units can synchronize several hydraulic axes with minimal external hardware. That arrangement lets the controller handle synchronized starts, stops, and profile changes while keeping hydraulic response closely tied to command values from the higher-level machine control.

This unit is supplied for 3 hydraulic axes, allowing independent closed-loop control on each axis without additional add-on cards. A configuration without a bus connection leaves the fieldbus slots open for systems that rely on point-to-point Ethernet or discrete wiring. Each of the three I/O boards has 2 current inputs per slot for feedback signals, 1 current output per slot for proportional valve actuation, and 3 digital I/O slots for local logic tasks. This layout gives the unit onboard signal handling for valves, transducers, and discrete status devices without requiring separate interface hardware for every channel. The internal hardware is marked as component series 3, supports two voltage inputs per slot for pressure or position transducers, and omits an inductive position sensor when external displacement transducers are used.

For communication with the machine controller, the card supports a 992-byte cyclic I/O limit while maintaining a 2 ms minimum bus cycle so hydraulic control loops remain responsive. Two integrated Ethernet ports operate at a 100 Mbit/s transfer rate, which allows line topology without a separate switch. A dedicated 24 VDC sensor supply powers external encoders, and the module also provides 10 VDC reference and 5 VDC excitation for incremental feedback devices. In addition, the controller offers 20 digital outputs for signaling and control functions within mid-scale hydraulic automation systems.
