VT-HNC100-1-14/132
The VT-HNC100-1-14/132 digital axis controller from Bosch Rexroth Indramat belongs to the VT-HNC Digital Axis Controllers family, delivering precise analog and current outputs for demanding industrial automation. This robust controller features 4 differential analog input channels rated at ±10 V (±15 V max) with an input resistance of 200 kΩ ±2% and a resolution of 5 mV. On the output side, it provides an analog output resolution of 1.25 mV and supports both 4–20 mA normative and ±23 mA high-drive current modes with a maximum load resistance of 500 Ω. Operating within a temperature range of 0 °C to 50 °C, this axis controller ensures consistent performance under typical factory conditions.
Technical prowess is evident in its multi-interface design: it supports RS232 at 9.6 kBaud, Profibus DP up to 12 MBaud, CANopen and INTERBUS-S, facilitating seamless integration into existing fieldbus networks. Position feedback is handled by dedicated transducer channels—four differential voltage inputs (0–1 V low, 2.8–5.5 V high, 250 kHz) and two inductive position transducer channels (2 V supply, 30 mA per channel, < 0.1% linearity). An integrated +5 VDC ±5% encoder supply (up to 200 mA) powers transducers directly. Precise voltage reference rails of –10 V / +10 V ±25 mV at 20 mA are available for sensor conditioning, while voltage non-linearity is kept below 15 mV within ±9.5 V and 35 mV beyond. The combination of 100 Ω ±0.2% current inputs (4–20 mA, 5 µA resolution) and the high-resolution analog outputs ensures sub-millivolt and microamp control fidelity.
This controller’s operational features include independent dual-channel control loops for synchronized multi-axis coordination and real-time responsiveness. With <200 kΩ> input impedance on voltage channels and <100 Ω> on current channels, sensor loading is minimized, preserving signal integrity. Built-in fault detection leverages the baseline 4 mA current fault threshold, reducing downtime by distinguishing between valid zero-load and fault conditions. High drive flexibility in the ±23 mA mode accommodates heavy loads or extended cable runs, while low voltage non-linearity guarantees predictable actuator motion and repeatable system response. Robust design and conservative thermal limits allow continuous operation in harsh industrial environments without derating.
Integration into advanced automation systems is simplified through support for major industrial fieldbuses and serial links, enabling direct communication with PLCs, HMIs, and motion controllers. The versatile analog and current I/O—combined with encoder supply and precision reference voltages—allows seamless interfacing with a wide range of sensors, actuators, and transducers. Typical applications include multi-axis gantries, servo valve control, rotary and linear actuator positioning, and other precision motion tasks in packaging, robotics, and machine tooling. With its comprehensive specification set and flexible connectivity, the VT-HNC100-1-14/132 provides a dependable, high-performance solution for demanding industrial motion control.
