Product Description:

The VT-HNC100-2-3X-P-I-00-000 is a digital axis controller produced by Bosch Rexroth Indramat and belongs to the VT-HNC Digital Axis Controllers series. Designed for hydraulic motion equipment, the module serves as the central NC unit that executes closed-loop position and force control on machine tools, presses, or handling stations. It interprets sensor feedback, generates valve commands, and coordinates two hydraulic axes so that motion sequences follow programmed setpoints with the timing accuracy required in industrial automation. This arrangement supports repeatable axis behavior during clamping, forming, transfer, and positioning cycles where motion and pressure must remain closely coordinated.

The axis version is tailored for two hydraulic axes, and the controller offers 4 analog current inputs, four analog voltage inputs, two analog current outputs, and four analog voltage outputs so that both motion channels have independent feedback and command paths. For discrete signals, the unit provides 22 digital I/O channels, and up to two encoder channels capture incremental or absolute position data. These interfaces let the controller process separate feedback and command signals for each hydraulic channel without sharing analog paths. Because the device is supplied without a bus connection, fieldbus communication must be realized through external gateway modules or the front-side service port. Parameterization and diagnostics are handled over the RS232 service interface, and the housing carries a protection rating of IP20 for installation inside a control cabinet.

For cabinet assembly, the unit clips onto a 35 mm mounting rail manufactured to the EN 60715 standard, allowing quick removal from the cabinet when needed. Rail mounting also helps keep the controller aligned with adjacent cabinet modules. Internal electronics are powered by a sensor supply of 24 V DC, which also feeds external transducers that share common return lines with the controller. This supply helps simplify wiring for connected measurement devices on the hydraulic system. Up to 20 digital outputs can drive solenoid valves or relays without additional output modules, and the Series 3 hardware supports this channel density.
