Product Description:

The VT-HNC100-1-1X-160-1 is a digital axis controller manufactured by Bosch Rexroth Indramat and included in the VT-HNC Digital Axis Controllers series. Derived from the HNC100 digital NC platform, its embedded electronics execute closed-loop control routines that convert programmed setpoints into valve currents while monitoring sensor feedback in real time. Installed in a control cabinet, the unit supports coordinated hydraulic motion in presses, assembly stations, and endurance test equipment where repeatable response and stable feedback processing are required. Its purpose is to manage axis behavior directly at the control level, so command processing, feedback evaluation, and output correction occur inside one compact module.

This controller is supplied as the axis variant for one hydraulic axis and belongs to component series 1. For cabinet power budgeting, it dissipates only 8 W. The analog reference range reaches ±10 V, giving symmetric headroom for command and feedback scaling in both directions of motion. Absolute position signals are accepted over SSI with 28 bits of data, while incremental encoders can be read at up to 250 kHz. Two current output channels can each drive proportional valves or servo amplifiers across loads up to 500 Ω. The analog acquisition path resolves 5 µA on current loops and 5 mV on voltage lines, which helps the controller react smoothly to small changes in pressure, force, or displacement signals.

System wiring is simplified by 4 current input channels that present 100 Ω impedance, which keeps the input burden low for connected transmitters. An equal number of voltage input channels terminate at 200 kΩ resistance to avoid loading position transducers, and four voltage outputs can source or sink up to ±10 mA per channel for drive or pilot functions. A transistorized switch output delivers 50 mA for auxiliary valve actuation, while the RS232 interface communicates at 9.6 kBaud for diagnostics and parameter transfer. Separate current, voltage, switching, and encoder connections allow the controller to handle sensing and actuation tasks within the same hardware without requiring an additional motion control module.
