Product Description:

The VT-HNC100-1-1X-130-3 digital axis controller is produced by Bosch Rexroth Indramat and forms part of the VT-HNC Digital Axis Controllers series. Within the Digital NC control HNC100 product series, this unit serves as the closed-loop control core for hydraulic positioning tasks, delivering command, feedback, and sequencing for servovalves, transducers, and pump drives on a single machine axis. The axis version is configured for one hydraulic axis, which keeps valve and sensor control on a dedicated channel for predictable motion behavior in presses, die-cushion systems, and molding equipment.

Analog command quality is supported by an output resolution of 1.25 mV, enabling fine valve current modulation. For current feedback channels, the module presents a precision shunt of 100 Ω ±0.2%, paired with 5 µA resolution so differential-pressure sensors or load cells on a 4–20 mA loop are sampled accurately. Voltage feedback lines see 200 kΩ ±2% impedance and 5 mV resolution, while high-impedance sensor inputs exceed 10 MΩ to avoid loading delicate signal sources. Incremental encoder ports accept edge rates up to 250 kHz, and SSI links handle 28-bit absolute data for position acquisition. Program and nonvolatile data storage are secured in 1 MB of flash plus 8 KB of EEPROM, both identified as component series 1, and total board demand stays at 8 W for compact control cabinets. Digital inputs use 3 kΩ ±10% pull-ups.

Execution speed is supplied by a 16/32-bit MC68376 processor that accesses 256 KB of RAM for cyclic interpolation and error handling during closed-loop operation. Each transistorized output can deliver up to 50 mA, enabling direct drive of indicator lamps or pilot valves without external amplifiers. Serial commands and software downloads are routed through an RS-232 interface that operates at 9.6 KBaud, supporting parameter transfer and service communication.
