How to Identify Your Siemens Servo Motor or S120 Drive
Correct identification of your Siemens servo motor (1FK2, 1FK7, 1FL2, 1FL6) or SINAMICS S120 drive module begins with the complete order number. This guide explains where to locate it and what information to provide when requesting a quote.
Step 1: Locate the Nameplate
The full order number is always printed on the original nameplate of the motor or drive. It typically appears as a single line starting with 1FK, 1FL, or 6SL.
- Servo motors: The label is usually located on the housing near the mounting flange or cable entry.
- SINAMICS S120 drives: Check the front or side of the power or control module.
Do not rely on handwritten notes, partial numbers, or unclear photos. The complete order number, exactly as printed on the original nameplate, is required for accurate identification.
You can browse the listed order numbers in the 1FK2, 1FK7, 1FL2, and 1FL6 servo motor sections and the SINAMICS S120 drive modules.
Provide the Full Order Number for Accurate Matching
To ensure correct identification, please include:
- The complete order number as printed on the nameplate
- A clear photo of the nameplate
- Any existing documentation you may have (e.g., purchase records, maintenance logs, equipment manuals)
Catalog entries provide model and series only. Physical similarity does not establish compatibility. Confirm the complete order number and the requirements for your equipment before ordering.
Common Questions When Identifying Parts
Can I replace a 1FK7083-2AF71-1CA1 with a 1FK7083-2AF71-1RA0?
Consult the machine manufacturer or a qualified technician using the equipment documentation. Catalog entries provide model and series only. Physical similarity does not establish compatibility. Confirm the complete order number and the requirements for your equipment before ordering.
My motor has no visible nameplate—what should I do?
Check your existing purchase records, maintenance logs, equipment manuals, or external labels. If the original order number cannot be confirmed, compatibility cannot be verified. Do not attempt to open terminal boxes or remove covers unless authorized by qualified personnel.
Are S120 drive modules interchangeable within the same series?
Consult the machine manufacturer or a qualified technician using the equipment documentation. Catalog entries provide model and series only. Physical similarity does not establish compatibility. Confirm the complete order number and the requirements for your equipment before ordering.
Do you supply documentation to verify specifications?
Documentation availability must be confirmed during the inquiry process. If you already have relevant technical files, please include them with your request.
