Servo Motors and Encoder Cables

Choosing Servo Motors and Encoder Cables components

Servo cables are not generic — the connector at each end is brand- and frame-specific, the shielding scheme matches the drive's EMC expectations, and the conductor count and gauge tie to the motor's current and feedback type. Substituting "any shielded servo cable" almost always introduces faults.

Specs to confirm before ordering:

Motor power cable: length, conductor count (3+PE for non-brake motors, 4+PE or 6+PE with brake leads), conductor gauge sized to motor current AND length, shield type (overall braid + foil), and matched connector at each end
Feedback cable: matched to the encoder/resolver type (resolver = different conductor count than absolute serial), drive-end connector specific to the drive family
Continuous-flex rating if the cable runs in a cable carrier — standard installation cable fails quickly in flex applications
Bend radius rating, especially in tight cable carriers
Temperature rating for hot motor locations or cold storage
UL/CSA listing for North American installations

Common gotchas: shorter cable assemblies are often listed by exact length codes — a 5 m and a 7 m Kinetix 2090 cable have different part numbers, and using a 7 m where a 5 m was specified means coiling the excess (which adds inductance) or running it long. Continuous-flex cables look identical to installation cables but use specially stranded conductors and a different shield construction; using non-flex cable in a cable carrier produces shield failures and intermittent encoder faults within months. Connector orientation (straight vs. 90°) is part of the SKU — a straight connector where 90° was specified often will not fit the panel cutout.

Typical replacement scenarios: cable damaged by chafe in a cable carrier, connector damaged by repeated mating cycles, shield failure causing erratic drive faults, and length changes during machine re-layout. On legacy machines, matching the original cable part number preserves the EMC performance the drive was certified with.

For obsolete or specific servo cable assemblies, send the OEM part number for a quote.

Do you stock obsolete Kinetix and Sigma cables?

Yes. Discontinued Kinetix 2090-CPxM7 and 2090-XXNFMP, end-of-life Yaskawa SGMG cable codes, retired MR-PWS and MR-EKCBL variants are sourced through our supplier network.

Can I use a generic shielded cable instead of OEM?

For short runs with proper connectors and termination by an experienced technician, sometimes yes. For long runs, continuous-flex applications, and high-EMI environments, OEM cables are usually the safer choice — they are EMC-qualified with the drive and avoid warranty disputes.

Standard cable vs. continuous-flex — does it matter?

Yes. Standard installation cable used in a cable carrier fails within months — the conductor stranding and shield construction are not built for repeated flexing. Always use continuous-flex (chain-rated) cable in cable carriers and on moving axes.

Can cables be made to custom length?

For most modern OEM cable families, yes — pre-terminated cables are available in many standard lengths and can sometimes be custom-built. Send the drive and motor part numbers along with the needed length.

How are cables shipped?

Coiled in protective packaging from St. Louis. Longer cables ship in shaped cartons to prevent kinking. Free US shipping over $50, international over $350.

What is the warranty?

12 months functional. Damage from chafe, kink, over-bend, or mechanical strain from missing strain reliefs is not covered.
