6FX5002-2CG00-1AG0 | Siemens MOTION-CONNECT Signal Cable — 810D/611D to Incremental Encoder / 7m / DESINA / UL/CSA

Pre-Assembled Encoder Signal Cable for 810D/611D Drive Systems

The 6FX5002-2CG00-1AG0 is Siemens' pre-assembled signal cable for connecting the encoder (feedback) circuit from a SINUMERIK 810D CNC controller or SIMODRIVE 611D servo drive to the servo motor's incremental encoder. At 7m, it serves the medium cable run distance between the drive cabinet and the motor installation position.

The encoder signal cable carries the incremental encoder feedback data that the drive uses to determine motor speed and rotor position — the continuous, real-time feedback that enables closed-loop servo control. Signal integrity in this cable is critical: noise coupling, impedance mismatch, or contact resistance in the encoder circuit directly degrades servo system accuracy and can cause drive faults.

Key Specifications

Conductor Configuration — Signal Pair Engineering

The 4×2×0.34mm² + 4×0.5mm² conductor configuration is engineered for the specific signal types in an incremental encoder connection:

4 twisted pairs at 0.34mm²: The primary encoder signal conductors — carrying the A, A*, B, B* differential signal pairs (A and A-bar, B and B-bar). Twisted pair construction cancels common-mode noise, maintaining encoder signal integrity in the electrically noisy environment near servo drives.

4 individual conductors at 0.5mm²: Auxiliary conductors for encoder power supply, reference (Z) pulse, and cable shield connection — the supporting functions beyond the main incremental signal pairs.

Overall shield: The DESINA cable construction includes an overall screen — grounded at the drive end to divert induced noise away from the encoder signal conductors.

Applications

SINUMERIK 810D CNC machine tools: Machining centres, turning centres, and grinding machines using the 810D/611D drive platform — this cable connects each motor's incremental encoder to its 611D drive module.

SIMODRIVE 611D servo installations: Any 611D-equipped machine tool installation using incremental encoder motors that requires the CG00-type encoder cable between drive and motor.

Machine retrofit: Older machine tools being retrofitted or maintained — the 6FX5002-2CG00-1AG0 provides the correct pre-assembled cable for drive system repair without field assembly.

FAQ

Q1: What is the difference between 6FX5002-2CG00 and 6FX5002-2CA12 in encoder signal cables?

6FX5002-2CG00 is for 810D/611D drive systems with incremental encoders using the CG00 connector interface. 6FX5002-2CA12 is for HTL and TTL encoder types with a different connector configuration. Both carry incremental encoder feedback but for different encoder connector styles and drive interface types. Confirm the specific encoder type and drive connector from the SINUMERIK or SIMODRIVE system documentation before selecting the encoder cable type.

Q2: What is the maximum cable length for incremental encoder signals in a SINUMERIK 810D system?

Maximum encoder cable length depends on the drive system and encoder type. The 811D/611D documentation specifies maximum cable lengths to ensure signal integrity — typically in the range of 25–50m for standard incremental encoders, depending on encoder signal frequency and cable capacitance. The 6FX5002-2CG00-1AG0's 7m length is well within typical maximum cable length limits. For longer runs, confirm maximum length from the SIMODRIVE 611D technical manual.

Q3: Does 6FX5002-2CG00-1AG0 comply with UL/CSA requirements for North American installations?

Yes — the UL/CSA designation in the cable specification confirms compliance with UL (Underwriters Laboratories) and CSA (Canadian Standards Association) standards. This compliance is required for machine tools and industrial automation equipment installed in North American facilities under NEC and CSA electrical code requirements. UL/CSA compliance simplifies approval of SINAMICS/SINUMERIK machine installations by certified inspectors.

Q4: Can 6FX5002-2CG00-1AG0 be used in continuous cable track (drag chain) applications?

The 6FX5002-2CG00 MOTION-CONNECT 500 Basic Line cable is designed for static or slowly moving installations, not continuous cable track flexing. For applications requiring continuous cable track use with encoder feedback cables, use the MOTION-CONNECT 800 Dynamic Line equivalent — rated for the number of flex cycles required by the specific cable track application.
