Product Description:

The VT-HNC100-1-2X-W-08-C-0 digital axis controller is produced by Bosch Rexroth Indramat as part of the VT-HNC Digital Axis Controllers series. Installed in a wall-mounted housing that is 155 mm high and 204 mm deep, this unit supervises closed-loop motion on hydraulic machinery. By processing feedback and command data, it modulates proportional valves so that a single hydraulic cylinder reaches target positions and velocities with repeatable accuracy. This control method helps presses, test stands, and forming equipment respond consistently when hydraulic load conditions change during operation.

The controller is supplied as the version for one hydraulic axis, and it belongs to component series 2 of the Digital NC Control HNC100 product line. Signal acquisition passes through 4 analog current inputs and four analog voltage inputs that monitor pressure, position, or temperature signals from the machine. Actuator commands are delivered by two analog current outputs and 4 analog voltage outputs for proportional valve electronics. Fieldbus integration is available over CANopen, while an auxiliary RS232 port supports local setup and service access. Because the base hardware is supplied without evaluation electronics and without an inductive position sensor, external conditioners and transducers can be selected to match the application.

The unit has 8 digital I/O points that can be assigned to limit switches, enable signals, or status relays without extra modules. It accepts quadrature, SSI, or RVDT feedback devices at frequencies up to 250 kHz, allowing high-resolution position signals to be tracked during rapid cylinder movement. Internal losses are limited to 8 W, which helps simplify cabinet thermal design. The slim 71 mm profile also conserves panel space beside power supplies and valve amplifiers. This arrangement allows one controller to handle motion feedback and standard machine-state signaling within the same enclosure.
