Product Description:

The VT-HNC100-2-3X-P-I-E0-G02 digital axis controller is manufactured by Bosch Rexroth Indramat as part of the VT-HNC Digital Axis Controllers series. It serves as a compact NC platform that supervises two hydraulic axes, converting setpoint data into precise valve currents so cylinders or hydrostatic tables reach commanded positions during automated production. The unit accepts either incremental or SSI transducers, allowing different feedback wiring methods while maintaining two-axis synchronization.

Each axis obtains a stabilized reference of +10 V for sensors, while measured currents are digitized with a resolution of 5 µA. This granularity lets the control loop trim valve magnet current without visible steps. Analog measurement channels also resolve signals down to 5 mV, which supports fine scaling of pressure or position transducers. Up to 11 digital I/O lines per axis accommodate limit switches, enable contacts, and diagnostic bits, and two analog outputs deliver proportional commands to external devices. Incremental feedback tracks edge rates up to 250 kHz, allowing high-speed encoders to pass position data without loss. A designation of without bus connection means fieldbus couplers are omitted, keeping the controller dedicated to local TCP/IP service access.

An SSI channel handles words up to 28 bits, matching modern absolute encoders that convey multi-turn information in one frame. Motion calculation is executed by a 32-bit PowerPC processor, giving deterministic cycle times even when both hydraulic loops run simultaneously. The housing is rated IP20, so the unit must be installed inside a control cabinet, and its 88 mm width with a height of 120 mm helps conserve panel space. The component belongs to series 3 of the HNC100 product family, and the TCP/IP service interface supports parameter access.
