Product Description:

The VT-HNC100-1-2X-W-08-P-0-ENDA is a digital axis controller manufactured by Bosch Rexroth Indramat within the VT-HNC Digital Axis Controllers series. It is designed to control one hydraulic axis, providing closed-loop motion control for presses, die-casting machines, and other fluid-power modules that require precise position and velocity regulation. By converting target values from a higher-level PLC into analog ±10 V signals or fieldbus commands, the unit drives proportional or servo-hydraulic valves and coordinates hydraulic movement with the surrounding automation.

This controller communicates over DP Profibus, allowing integration into distributed control systems at data rates up to 12 MBaud. The unit provides 8 digital I/O for limit switches, enable commands, and status feedback. It belongs to component series 2 and is supplied without an inductive position sensor, so external feedback devices must be connected to the EnDat or 1 Vss encoder inputs. Incremental encoders can be sampled at a maximum of 250 kHz, while the RS232 service port supports diagnostics at 9.6 KBaud. For analog valve control, the reference output is ±10 V. Gray-coded SSI transducers are also supported, and the controller can process EnDat absolute encoders for single-turn or multi-turn positioning. The wall-mount housing is intended for control cabinet installation within the HNC100 product line.

The mechanical package is compact, with a width of 71 mm, a depth of 204 mm, and a height of 155 mm, so multiple axes can be arranged side by side without exceeding standard panel depths. Net mass is 1.0 kg, which helps reduce load on light-gauge subplates. The SSI receiver supports data words of 28 bits, accommodating fine position resolution when long-stroke cylinders require very accurate feedback. Gray code transmission helps reduce bit errors under electromagnetic interference, and the metal enclosure shields the internal electronics while allowing convection cooling through cabinet airflow.
