Description

Product Overview

The Rexroth VT-HNC100-1-23W-08-P-0 is a programmable digital axis controller from the VT-HNC100 family, designed for closed-loop control of hydraulic drives. It is configured for one hydraulic axis, wall mounting, eight digital inputs/outputs, and a PROFIBUS DP bus connection. The controller can execute NC programs for position, velocity, pressure, and force control, making it suitable for hydraulic presses, forming machines, injection equipment, and other motion systems requiring coordinated closed-loop regulation. Bosch Rexroth documentation describes the VT-HNC100 platform as a programmable motion controller capable of controlling up to four axes, while the specific ordering code defines the one-axis configuration and PROFIBUS interface. The complete reference is also associated with order number R90095899 in supplier records.

Technical Specifications

Supplier records report approximately 70 mm height, 155 mm width, 200 mm depth, and 0.94 kg weight. The available technical references should be checked against the nameplate for an exact revision.

Key Features and Benefits

• Dedicated control of a hydraulic axis in closed-loop applications.
• Programmable NC functionality for motion and process control.
• Eight configurable digital inputs/outputs.
• PROFIBUS DP connectivity for integration with a higher-level automation system.
• Supports hydraulic position, velocity, pressure, and force control functions.
• Wall-mounted construction suited to industrial control cabinets.
• Suitable for legacy hydraulic automation systems where exact controller replacement is required.

Personally, I would verify the complete ordering code and installed feedback type before selecting a replacement. The VT-HNC100 family contains several variants, and the bus interface and axis configuration directly affect system compatibility.

VT-HNC100-4 Series — Higher-axis configuration for applications requiring coordinated control of multiple hydraulic axes.

Installation and Maintenance

Before installation, confirm the supply voltage, hydraulic-axis configuration, PROFIBUS network parameters, feedback device, sensor wiring, and NC program compatibility. Check the existing controller’s parameter backup before removal whenever possible.

During maintenance, inspect field connectors, encoder wiring, communication cables, mounting points, and cabinet ventilation. Hydraulic control faults should not automatically be attributed to the controller; valve electronics, pressure sensors, position transducers, and wiring can produce similar symptoms.

Follow the plant’s electrical isolation and hydraulic pressure-release procedures before removing the controller. After replacement, verify communication, feedback scaling, valve command direction, limit settings, and closed-loop response before returning the equipment to production.

Product Warranty

Warranty coverage depends on supplier, stock condition, and purchase agreement. Confirm whether the unit is new old stock, refurbished, tested used, or surplus, and request the exact hardware revision and test status before procurement.

The Rexroth VT-HNC100-1-23W-08-P-0 is best managed as a dedicated hydraulic motion-control spare where preserving the original PROFIBUS-based architecture is important.
