Product Description:

Bosch Rexroth Indramat manufactures the VT-HNC100-2-3X-C-I-00-000, a digital axis controller positioned within the VT-HNC Digital Axis Controllers series. Classified under the Digital NC control HNC100 product series, the module is supplied as component series 3 hardware and is intended for 2 hydraulic axes, making it suitable for synchronized ram or clamp positioning in industrial hydraulic machinery. By combining motion control, analog acquisition, and discrete output functions, the unit provides a compact command platform for closed-loop automation.

In the control cabinet, the device installs on a top hat rail and carries a protection rating of IP20, so all terminations remain finger-safe while relying on cabinet sealing for protection. In this two-axis configuration, the controller allocates independent PID channels to each actuator while sharing common resources. Connectivity to higher-level PLCs is optional, and this model ships without a bus connection, so setpoints reach the axis cards through analog references or SSI links. Signal distribution is organized by slot, with each slot providing 2 voltage inputs, 2 voltage outputs, 2 current inputs, and 1 current output. Up to 20 digital outputs can drive valves, contactors, or status lamps, and incremental or SSI position feedback completes the closed loop, while no inductive position sensor is included.

Power distribution inside the module separates low-level logic rails from field power. The encoder interface is stabilized by a dedicated 5 VDC logic line, while transducers draw on a galvanically isolated 24 VDC supply that also serves the sensor terminals. An internal reference source delivers 10 VDC to the voltage input channels, which helps reduce offset drift in proportional-valve control. Overall supply integrity is maintained with a ripple of <1.5 Vpp, ensuring clean current measurements and consistent spool positioning without external filters.
