6FX5002-2CA31-1BA0 | Siemens Signal Cable — Incremental Encoder Voltage Signal + C/D Tracks / 10m / MOTION-CONNECT 500 / MC/HP GMC

Voltage Signal Encoder Cable with C/D Tracks — What Distinguishes 6FX5002-2CA31

The 6FX5002-2CA31-1BA0 carries a specific combination of encoder feedback signals: sinusoidal voltage signals (1Vpp) for the main incremental position tracks plus C/D commutation signals from the motor encoder's additional track layers. This cable is the MOTION-CONNECT 500 Basic Line equivalent of the 6FX8002-2CA31 — carrying identical signal types in a static-installation (non-dynamic) cable construction.

Within Siemens' servo encoder cable portfolio, the "voltage signal" designation identifies the encoder output type as sinusoidal analogue (typically 1V peak-to-peak) — distinct from "current signal" encoders (HTL/TTL square wave) which use different cables. Voltage signal encoders offer higher noise immunity and greater interpolation potential at higher signal frequencies than TTL encoders.

Key Specifications

6FX5002-2CA31 vs 6FX8002-2CA31 — Choosing the Right Series

Both carry identical signal types — voltage signal incremental encoder with C/D tracks, with the same conductor configuration and connectors. The difference is the cable construction and application:

6FX5002-2CA31 (this cable): MOTION-CONNECT 500 Basic Line — static or slowly moving installations, cable track traversing up to 5 metres. Cost-effective choice for fixed routing.

6FX8002-2CA31: MOTION-CONNECT 800PLUS Dynamic Line — continuous cable track service up to 50 metres traversing distance, PUR outer sheath, enhanced oil resistance. Required for dynamic cable track applications.

Applications

SINAMICS S120 servo axes — static cable routing: CNC machining centres, turning centres, and grinding machines with fixed cable routes between drive cabinet and motor — where MOTION-CONNECT 500 Basic Line is the appropriate and cost-effective choice.

High-precision servo positioning: Servo axes using 1Vpp voltage signal encoders for fine position resolution — the sinusoidal signal enables high interpolation within each encoder period.

CNC machine tool retrofit: Replacement encoder feedback cables for machines undergoing drive system repair or upgrade — where the fixed-installation routing does not require Dynamic Line cable track capability.

Industrial automation drives: SINAMICS-based servo positioning systems in automated machinery with fixed cable routing between cabinet and motor mounting positions.

FAQ

Q1: What is the difference between 6FX5002-2CA31 (voltage signal) and 6FX5002-2EQ10 (absolute encoder)?

6FX5002-2CA31 carries analogue sinusoidal (1Vpp) incremental encoder signals with C/D commutation tracks — used with optical or magnetic incremental encoders that generate sinusoidal output. 6FX5002-2EQ10 carries EnDat absolute encoder signals — used with digital absolute encoders that transmit position data serially. The motor's installed encoder type determines which cable is required.

Q2: How does the C/D track cable differ from a standard incremental encoder cable without C/D tracks?

A standard incremental cable (e.g., 6FX5002-2CA12) carries only the ABR sinusoidal signals — for motors where commutation is handled by a separate Hall sensor or the drive performs a pole-finding procedure at startup. The 6FX5002-2CA31 with C/D tracks adds the 4×0.22mm² conductor group for the C and D sinusoidal commutation channels — for motors where the encoder assembly integrates both incremental position and commutation information in one device. This eliminates the startup pole-finding sequence.

Q3: Can 6FX5002-2CA31-1BA0 be used in a cable track if the axis travel is under 5 metres?

Yes — MOTION-CONNECT 500 is rated for cable track use with traversing distances up to 5 metres per the MOTION-CONNECT specification. For axis travel within this limit, the 6FX5002-2CA31-1BA0 can be installed in a cable track. For axis travel exceeding 5 metres, the 6FX8002-2CA31 Dynamic Line variant is required.

Q4: Why does 6FX5002-2CA31-1BA0 have a 9.9mm diameter when the resolver cable (6FX5002-2CF02) is 9.2mm?

The 6FX5002-2CA31 carries 16 conductors (including 4×0.22mm² C/D conductors) vs 12 conductors in the resolver cable. The additional conductor bundle increases the cable cross-section and outer diameter. The 0.7mm difference (9.9 vs 9.2mm) must be accounted for in cable tray fill calculations and cable track width specifications when routing both types in the same channel.
