Product Description:

The VT-HNC100-3-3X-N-I-00-G03 is a digital axis controller produced by Bosch Rexroth Indramat and placed within the VT-HNC Digital Axis Controllers series. Designed as a compact motion unit for hydraulic machinery, it converts numeric trajectory data into valve-level commands that drive cylinders, presses, or gantry elements. Its control concept is derived from the Digital NC control HNC100 platform, enabling deterministic multi-axis interpolation inside the cabinet rather than in a separate PLC. It is intended for hydraulic applications that require coordinated position and pressure control across multiple moving elements.

This unit is supplied in a version for 3 hydraulic axes. The control loop runs with a minimum cycle of 2 ms, so command latency stays inside servo tolerances. Field wiring is simplified by 11 configurable digital inputs or outputs per axis, and two voltage input channels with 200 kΩ ±5% impedance capture analog references. Real-time traffic is handled through a PROFINET IO RT device interface at 100 Mbit/s full-duplex. No plug-in SERCOS or CAN bus card is included. Incremental encoder tracks are accepted at up to 250 kHz, and three-axis synchronization keeps cylinders phase-aligned. The controller follows conformance class A guidelines, and diagnostic telegrams are transmitted in deterministic network slots.

Computation is handled by a 32-bit PowerPC that completes position, velocity, and pressure loops during every scan. The controller publishes a cyclic process image of 992 bytes, giving the supervisory PLC direct access to setpoints and status bits without fragmented packets. An internal reference of +10 V ±25 mV supplies ratiometric sensors, while absolute position devices connect through an SSI channel that accepts words up to 28 bits. This arrangement allows sensor values and command data to be exchanged in a consistent format during synchronized hydraulic motion.
