Siemens 6SL3260-4MA00-1VB0 is a pre-assembled I/O cable designed to simplify wiring between a SINAMICS V90 PROFINET servo drive and the rest of your control system. In real-world motion projects, the “small parts” (cables, connectors, terminations) often decide whether commissioning is smooth or turns into a week of intermittent faults and finger-pointing. This cable exists to remove variables: it is built to a defined Siemens accessory specification, delivered as a finished assembly, and intended to provide a predictable interface for I/O connectivity in V90 PROFINET applications.
From a system-integration perspective, an I/O cable like this is not about bandwidth or fancy features. It’s about reliability, traceability, and repeatability. Servo drives live in electrically noisy environments: fast switching edges, motor cables, braking resistors, contactors, and grounding topology all compete to inject noise into low-level signals. Using a correct, purpose-built assembly helps keep the I/O side tidy and mechanically secure, reducing the chance of loose terminations, wrong pinouts, or improvised connector choices. The 6SL3260-4MA00-1VB0 is specified as a 1 meter pre-assembled I/O cable for SINAMICS V90 PROFINET, making it a good fit for cabinet layouts where the drive and I/O interface are relatively close, such as compact single-axis machines or multi-axis panels with short internal harness runs.
A practical detail that matters: this cable is commonly described with a 20-pin MDR connector on one side (with free pins/termination on the controller side, depending on the application approach). That style is widely used for compact, higher-density signal interfaces, giving you a robust mechanical connection and clear mating orientation—useful when you want consistent servicing procedures across machines.

What this cable helps you achieve in a V90 PROFINET motion system
In a V90 PROFINET setup, motion commands and feedback travel over PROFINET, but practical machine operation still relies heavily on discrete signals: enabling logic, interlocks, safety-related permissives (as designed by your safety architecture), brake control strategies, and auxiliary status signals. Your drive may be perfect on the network side and still behave “mysteriously” if I/O wiring is inconsistent or mechanically weak. The goal of the 6SL3260-4MA00-1VB0 is straightforward: provide a known-good physical layer for the I/O connection so you can focus on commissioning logic, not troubleshooting harness improvisations.
Typical application scenarios
This accessory is a strong fit when you are building or maintaining:
-
Compact servo cabinets where the V90 PROFINET drive sits near the PLC I/O interface or terminal blocks (1 m length keeps routing clean).
-
Standardized machine platforms where service teams expect consistent, repeatable wiring interfaces across multiple machines and customer sites.
-
Retrofit projects where you want to replace a non-original or unknown cable assembly with something that matches a recognized Siemens accessory reference.
Installation and engineering notes that save time
Cable accessories look simple, but treating them as engineered parts pays off:
Cable routing: Keep signal cables separated from motor power cables where possible. If you must cross, cross at right angles and avoid long parallel runs. This reduces induced noise and helps prevent intermittent I/O behavior during high acceleration moves.
Strain relief: Use proper strain relief at the cabinet entry and near the drive. A robust connector is only as reliable as the mechanical support around it.
Labeling discipline: Put the Siemens part number on the harness label or BOM notes. When machines return for service after two years, the ability to identify “exactly which cable assembly” you used becomes surprisingly valuable.
Quality, compliance, and procurement-friendly details
From the purchasing side, small accessories are easiest to manage when they are traceable. The 6SL3260-4MA00-1VB0 is presented with standard logistics identifiers such as EAN 4042948674451, and is commonly listed with commodity code 85444290, which helps align shipping documents and HS-related paperwork.
For global shipments, some listings also note AL: N / ECCN: N, and indicate RoHS compliance, supporting common industrial procurement requirements.
Bottom line
If you are working with SINAMICS V90 PROFINET and want a tidy, repeatable I/O wiring approach, the Siemens 6SL3260-4MA00-1VB0 is the kind of accessory that quietly improves build quality. It is a short, pre-assembled 1 m I/O cable intended for V90 PROFINET systems, and it’s typically referenced with clear logistical data (weight, origin, commodity code) that makes sourcing and documentation easier across projects and regions.
