Product Description:

The VT-HNC100-1-3X-E-I-00-000 is a digital axis controller produced by Bosch Rexroth Indramat as part of the VT-HNC Digital Axis Controllers series. It is intended for closed-loop command of a single hydraulic axis, combining motion calculation, valve actuation, and monitoring in one DIN-rail module. Within industrial presses, forming machines, or injection systems, the device executes numeric positioning and pressure regulation so that the main PLC can focus on sequencing and safety rather than time-critical servo tasks.

Real-time performance is set by a minimum cycle time of 2 ms, allowing the controller to refresh internal algorithms five hundred times each second. Data exchanged with the master occupies up to 992 bytes per cyclic frame, giving ample space for setpoints, actual values, and status words. A bank of 11 configurable digital channels handles local limit switches, pump enables, or alarm outputs without extra I/O cards. Integrated sensor excitation delivers a regulated 24 VDC supply for potentiometers and proximity transducers. All telegrams pass through an embedded Ethernet switch that sustains a transfer rate of 100 Mbit/s, keeping bus latency low even under full payload.

For network topology, the board offers 3 RJ45 switch ports so multiple controllers can be daisy-chained without external hardware. Analog measurement is supported by 2 voltage input channels, which are useful for cylinder pressure or servo-valve spool feedback. Axis position can be returned through Incremental/SSI signals that use a drive-provided excitation of 10 VDC, accommodating both quadrature encoders and absolute sensors. Because this HNC variant is ordered without a dedicated fieldbus, higher-level coordination relies solely on standard Ethernet, and multi-axis synchronization is managed by the supervisory PLC rather than by the controller itself.
