Product Description:
The VT-HNC 100-1X-150 is a digital axis controller developed by Bosch Rexroth Indramat and supplied within the VT-HNC Digital Axis Controllers series. It serves as the closed-loop command unit for hydraulic or electromechanical axes, translating fieldbus or operator commands into precise analog and digital setpoints. By integrating measurement inputs, encoder counting, and drive outputs on a single card, the device coordinates position, velocity, and force loops used in presses, plastic machinery, and other industrial motion systems. This arrangement allows one control card to process feedback and issue actuator commands without requiring separate interface modules for each function. It can manage both sensor acquisition and command output for a single controlled axis, which is useful where hydraulic valves and feedback devices must stay tightly synchronized.
Four voltage input channels accept ±10 V signals and are digitized with 5 mV resolution, while four impedance-referenced inputs support bridge transducers over the same input range. A separate group of four current input channels measures 0–20 mA loops with a resolution of 5 µA, giving the controller fine sensitivity for pressure or flow sensors. Two current outputs and four voltage outputs generate reference commands, and their converter granularity is 1.25 mV so small control corrections can be issued smoothly. The incremental encoder interface tolerates count rates up to 250 kHz, which supports fast position feedback on moving axes. Application data is retained in a Flash array of 1 MB, supported by 8 KB of EEPROM for parameter sets. Overall power draw remains limited to 8 W, which helps reduce heat buildup inside the cabinet.
Real-time control algorithms are executed by a 16/32-bit MC68376 processor that combines timer units with on-chip converters to shorten loop update times. Working variables reside in 256 KB of fast SRAM, allowing position and pressure calculations to cycle without constant Flash access. For absolute transducers, the SSI channel supports word lengths up to 28 bits, and an RS-232 service port fixed at 9.6 KBaud provides a direct local connection for setup and diagnostics. These resources support coordinated sensing, computation, and command output across a complete machine axis.
