6FX5002-2EQ10-1BA0 | Siemens Absolute Encoder Signal Cable — 10m / 30V / M23 + Sub-D / MOTION-CONNECT 500 / MC/HP GMC / SINAMICS

Standard-Length Absolute Encoder Cable for SINAMICS Servo Systems

The 6FX5002-2EQ10-1BA0 is the 10-metre pre-assembled absolute encoder signal cable from Siemens' MOTION-CONNECT 500 range — the most widely used length in this cable type, covering the majority of standard drive cabinet-to-motor cable run distances in industrial servo applications. The 10m length suits typical CNC machine tool and industrial automation installations where drive cabinets are positioned at standard separation distances from machine axes.

Catalogued in Siemens' MC/HP - Cables GMC (Motion Control / High Performance, General Motion Control) product family, the 6FX5002-2EQ10-1BA0 is the specified encoder cable for SINAMICS S120 and related drive systems using absolute encoder-equipped SIMOTICS servo motors in static cable routing configurations.

Key Specifications

MC/HP GMC — Motion Control Cable Family

"MC/HP - Cables GMC" identifies the 6FX5002-2EQ10-1BA0 within Siemens' Motion Control / High Performance cable product family for General Motion Control:

MC/HP: Motion Control / High Performance — the cable category for SINAMICS drive system encoder and signal cables.

GMC (General Motion Control): The cable sub-family covering SINAMICS S120, S110, and related motion control platforms — encompassing both power and signal cables for the full SINAMICS drive-motor cable system.

Applications

SINAMICS S120 direct axis position feedback: CNC machining centres, turning centres, and grinding machines using SINAMICS S120 with absolute encoder SIMOTICS motors — direct homing-free axis position at startup.

CNC machine tool production environments: Production CNC facilities where eliminating startup axis homing cycles reduces non-productive machine time — each axis with absolute encoder feedback avoids its reference travel at every power cycle.

Industrial automation servo positioning: SINAMICS-controlled servo positioning in automated assembly, material handling, and precision automation — where absolute position retention through power-off events simplifies controller state management.

Machine tool retrofits: Replacement absolute encoder cables in machines undergoing SINAMICS drive or encoder system upgrades — the 10m length covers the majority of standard CNC machine tool axis cable runs.

FAQ

Q1: Why does the 6FX5002-2EQ10 encoder cable have more conductors than a resolver cable?

A resolver (3 signal pairs + supply = 8 conductors) is an analogue device requiring only excitation and sine/cosine channels. An absolute encoder with EnDat interface is a digital device communicating a serial protocol — requiring dedicated clock, data, and enable signal pairs alongside high-resolution analogue tracks and encoder supply. The additional function requires additional conductors, resulting in the 16-conductor design of the EQ10 cable vs. 12 conductors in simpler encoder cables.

Q2: How does the 10m (6FX5002-2EQ10-1BA0) and 15m (6FX5002-2EQ10-1BF0) differ in application?

Both cables are identical in specification — same conductors, diameter, connectors, and standards compliance. Length is the only difference: 10m for cable routes within 10m, 15m for routes between 10m and 15m. Measure the actual routing path and select the appropriate length. Using a 15m cable where 10m is sufficient creates excess cable that must be managed in the installation.

Q3: What is the maximum cable length for EnDat encoder feedback in SINAMICS systems?

The SINAMICS S120 SMC20 documentation specifies the maximum encoder cable length for EnDat absolute encoders. EnDat is a clock-synchronous protocol — at longer cable lengths, the transmission line delay and cable capacitance affect timing margins. Siemens specifies the maximum cable length to ensure reliable data transmission. Both the 10m and 15m variants are within typical maximum length specifications; confirm for specific EnDat clock rates from the SMC20 documentation.

Q4: Is 6FX5002-2EQ10-1BA0 compatible with SSI absolute encoders as well as EnDat?

The 6FX5002-2EQ10 cable construction (conductor count, shielding, and connector) is designed for the absolute encoder (EnDat) interface specific to SIMOTICS motors with integrated absolute encoders. SSI encoders use a different interface protocol and may have different pin assignments — the 2EQ10 cable is not automatically compatible with SSI encoder types. For SSI encoder connections, confirm from the specific encoder's interface documentation which MOTION-CONNECT cable type applies.
