6FX8002-2CF02-1AE0 | Siemens Resolver Signal Cable — 4m / M23 + 25-Pin Sub-D / MOTION-CONNECT 800PLUS / DESINA / SINAMICS

Short-Run Resolver Feedback Cable for Compact Drive Installations

The 6FX8002-2CF02-1AE0 is the 4-metre variant of Siemens' MOTION-CONNECT 800PLUS pre-assembled resolver signal cable — the compact-distance cable for drive installations where the servo motor sits close to the SINAMICS drive cabinet. At 4m, this cable serves intra-cabinet connections, short machine axes, and compact machining centres where motor and drive are within short reach.

The cable carries the complete resolver feedback circuit between the motor and the SINAMICS SMC10 Sensor Module or equivalent resolver interface: excitation supply from the drive to the resolver, and the analogue sine/cosine position signals from the resolver back to the drive.

Key Specifications

MOTION-CONNECT 800PLUS Trailable — Cable Track Rated

Despite its short 4m length, the 6FX8002-2CF02-1AE0 carries the full MOTION-CONNECT 800PLUS specification:

Continuous flex capability: The cable is rated for cable track (drag chain) service — finely stranded conductors, flexible PUR outer sheath, and torsion-resistant construction maintain signal integrity through continuous bending cycles.

Enhanced oil resistance: The 800PLUS designation adds resistance to cutting oils and hydraulic fluids beyond standard MOTION-CONNECT 800 — the resolver cable routes near motor surfaces where exposure to machine tool fluids is common.

DESINA compliance: The M23 connector interface and RAL colour coding comply with DESINA standards — ensuring interface consistency with SINAMICS drive hardware across product generations.

Applications

SINAMICS S120 with SMC10 — compact installations: SINAMICS S120 drive configurations using the SMC10 Sensor Module for resolver position feedback, where the motor-to-cabinet distance is within 4m — common in compact machining centres and bench-mounted test equipment.

SINAMICS cabinet-mounted motors: Servo motor positions immediately adjacent to the control cabinet — spindle motors on small CNC turning centres, feed axis drives on compact grinders, and similar short-run installations.

CNC machine tool commissioning spares: The 4m cable serves as a standard commissioning-length cable — useful when the actual cable routing needs assessment before ordering the definitive longer length.

FAQ

Q1: Why choose 6FX8002-2CF02-1AE0 over a longer variant for a short installation?

Using the correct length avoids excess cable in the installation — excess cable coiled or tied in the cable tray creates minimum bend radius violations and reduces EMC performance by creating an unintended antenna loop. For a 4m route, the 6FX8002-2CF02-1AE0 is the right cable. Adding routing allowance only: if the route is actually 3.5m, the 4m cable is appropriate; if it approaches 5m, the next longer length is required.

Q2: Is the resolver cable interchangeable between different SINAMICS sensor module variants?

The 6FX8002-2CF02 is specified for the SMC10 Sensor Module interface. Other SINAMICS feedback modules (SMC20, SMC30, DRIVE-CLiQ encoders) use different cable types. The resolver cable is not interchangeable with encoder signal cables — both physical connectors and pin assignments differ. Confirm from the SINAMICS S120 hardware configuration documentation that the SMC10/resolver combination applies before selecting this cable.

Q3: Does cable length affect resolver measurement accuracy in SINAMICS systems?

Longer cables increase total capacitance and resistance loading on the resolver excitation and signal circuits. Excessive cable length attenuates the sine/cosine signal amplitude reaching the SMC10's ADC input. The SMC10 documentation specifies the maximum cable length for the specific resolver type — the 4m cable is well within any standard resolver cable length limit and contributes minimal signal loading.

Q4: What shielding termination is required for 6FX8002-2CF02-1AE0?

The M23 and Sub-D connectors provide the shield termination at both ends — the connector housings ground the cable's overall shield to the motor frame (M23 end) and to the SMC10 module's chassis (Sub-D end). No separate field shield termination is required. Follow the SINAMICS S120 installation manual for the correct shield ground connection at the module end.
