REXROTH VT-HNC100-1-23/M-08-P-0 | Hydraulic Axis Module

Description

• Model: VT-HNC100-1-23/M-08-P-0
• Brand: Bosch Rexroth / Rexroth
• Part Type: HNC100 Digital Axis Control
• Axis Configuration: 1 hydraulic axis
• Installation: Rack mounting
• Digital I/O: 8 inputs/outputs
• Bus Interface: PROFIBUS DP

Technical Introduction

The Rexroth VT-HNC100-1-23/M-08-P-0 is a programmable HNC100 digital axis controller configured for one hydraulic axis, rack installation, eight digital inputs/outputs, and PROFIBUS DP communication. It belongs to the HNC100 family developed for closed-loop control of hydraulic drives and related machine-control applications.

For maintenance teams, the suffix is important. The /M identifies the rack-mounted variant, while 08-P-0 corresponds to the eight-channel digital I/O and PROFIBUS DP configuration reported for this specific version. Similar HNC100 variants use different mounting arrangements or bus interfaces, so a generic HNC100 replacement should not be assumed compatible.

Best Suited For

• Hydraulic motion-control systems and machine tools
• Replacement of an installed HNC100 rack controller
• Legacy automation spare inventory where PROFIBUS DP remains in service

Core Technical Specifications

The exact model is described by current aftermarket documentation as a rack-mounted HNC100 digital axis control for one hydraulic axis with 8 digital I/O and PROFIBUS DP. Bosch Rexroth maintains a product documentation and data-sheet portal, but detailed historical information for this specific legacy variant may require searching by material number or document ID.

Field Engineer’s Tech Notes

1. Verify the /M rack version before ordering.
The HNC100 family contains wall-mounted and rack-mounted variants. A unit with the same base controller designation but a different installation suffix is not necessarily a mechanical replacement. Check the existing rack, connectors, and cabinet layout before releasing the spare.

2. Treat the hydraulic control loop as part of the replacement check.
After replacing the controller, verify the axis feedback arrangement, proportional/servo output configuration, limit signals, and NC program before enabling hydraulic motion. An incorrect parameter set can cause an apparently healthy controller to command the wrong axis response.

Adaptive QA & Testing Protocol

For an HNC100 digital axis controller, incoming inspection should verify the complete VT-HNC100-1-23/M-08-P-0 identification, housing and rack-interface condition, connectors, switches or configuration elements where fitted, and evidence of corrosion or storage damage.

Functional testing should use an appropriate HNC100 test arrangement. The controller should be powered up and checked for initialization and diagnostics, followed by verification of the available digital I/O. The PROFIBUS DP interface should be checked for node communication and stable data exchange with the test master. Where the test setup supports it, the hydraulic-axis control path should be simulated with appropriate feedback and command signals rather than applying uncontrolled hydraulic motion.

The HNC100 family supports PC-based programming and NC-language functions, so the installed application’s program and configuration should be verified before the replacement is returned to service.

Test reports, inspection photographs, configuration records, and available test videos can be provided upon request.

Buyer’s FAQ

What is the REXROTH VT-HNC100-1-23/M-08-P-0?

It is an HNC100 Digital Axis Control configured for one hydraulic axis, rack installation, 8 digital inputs/outputs, and PROFIBUS DP.

Is it interchangeable with VT-HNC100 wall-mounted versions?

Not automatically. The /M version is identified as the rack-mounted configuration, while other HNC100 variants use wall mounting and may have different physical arrangements or interfaces. Verify the complete type designation before substitution.

Can this controller replace an existing HNC100 directly?

Only after checking the exact variant, installed hardware, PROFIBUS configuration, hydraulic-axis application, I/O mapping, and stored NC/control program. A matching base model alone is not sufficient.

What condition and warranty are available?

Depending on stock, the unit may be available as New Surplus (NSFP) or tested/refurbished inventory. Request confirmation of the exact condition, test scope, warranty period, and shipping lead time with the quotation.
