Technical Specifications

Note: Electrical parameters such as supply voltage range, analog input specifications, and communication interface details vary by firmware revision. DriveKNMS will confirm exact hardware revision upon inquiry. No parameters are published here that cannot be verified against physical unit markings.

Solving the Discontinued Hardware Crisis

The VT-HNC100-1-14/134 was designed for closed-loop electrohydraulic axis positioning in heavy industrial environments — press lines, injection molding machines, steel mill roll gap control, and marine steering gear systems. These are not applications where close enough is acceptable. The controller's proprietary command interface and tuning parameters are deeply embedded in the machine's PLC logic. Swapping it for a modern equivalent is not a drop-in exercise; it is a capital project.

Maintaining a strategic spare on the shelf converts a potential six-week production halt into a four-hour swap. For a line producing $50,000 per day, the arithmetic is straightforward.

Key Features for System Maintenance

• Drop-in replacement: The VT-HNC100-1-14/134 installs into the original mounting position using the original wiring harness. No mechanical modification is required.
• No PLC reprogramming required: Provided the replacement unit carries the same hardware revision and the parameter set is restored correctly, the host PLC does not require modification. This eliminates the need for a controls engineer to be present at commissioning in most cases.
• Avoids engineering retrofit costs: A full drive system retrofit on a single hydraulic axis typically requires 3–6 weeks of engineering time, new hardware, and a planned production shutdown. Sourcing the original part eliminates all of these costs.
• Preserves existing safety certifications: Replacing a like-for-like component does not trigger re-certification requirements in most jurisdictions. A platform migration may. This is a compliance consideration that is frequently overlooked in retrofit cost calculations.
