6FX2002-5DA31-1AK0 | Siemens MOTION-CONNECT Power Cable with Brake — 12m / 4×2.5mm²+2×1mm² / SIMODRIVE 1FT6 / Trailing Type

Combined Power and Brake Cable for SIMODRIVE 1FT6

The 6FX2002-5DA31-1AK0 is a pre-assembled combination cable carrying both servo motor power conductors and electromagnetic motor brake conductors in a single outer sheath. For SIMODRIVE 1FT6 servo motors with an integrated electromagnetic holding brake, this single cable replaces what would otherwise require separate power and brake cables — simplifying installation, reducing cable routing complexity, and minimising the number of connectors in the motor junction box.

The 6FX2002 series is the earlier generation of Siemens MOTION-CONNECT pre-assembled cables, designed specifically for the SIMODRIVE 611 servo drive and 1FT6 servo motor platform.

Key Specifications

Two Functions in One Cable — Power and Brake Combined

Motor power conductors (4×2.5mm²): Three phase conductors and one protective earth — the complete motor supply for three-phase servo motor operation.

Brake conductors (2×1.0mm²): The DC supply circuit for the motor's electromagnetic holding brake. The 1FT6 motor's internal brake releases when DC voltage is applied and re-engages automatically on power removal, providing fail-safe axis locking without additional external brake circuitry.

Combining both cable functions eliminates the need to route separate brake cables alongside the power cable — reducing cable tray fill, simplifying connector interfaces, and lowering installation time compared to separate cable systems.

Applications

SINUMERIK CNC machine tool axes: All servo axis drives using the SIMODRIVE 611/1FT6 combination on machining centres, turning centres, grinders, and other CNC machine tools.

Industrial automation positioning: Servo positioning systems using SIMODRIVE 611 amplifiers and 1FT6 motors — gantry systems, linear transfer machines, and precision positioning tables.

Handling and robotics: SIMODRIVE-based handling equipment where the trailing cable type supports axis travel.

FAQ

Q1: Why is the connector size important for 6FX2002-5DA31 cables?

The connector size (1.5 in this case) matches the physical size of the motor and drive connectors — different current classes of 1FT6 motor use different connector sizes (1, 1.5, 2, 3...). An incorrect connector size will not mechanically mate with the motor's power connector, regardless of electrical specifications. Confirm from the motor nameplate or technical documentation that connector size 1.5 is specified for the specific 1FT6 motor being connected.

Q2: Can 6FX2002-5DA31-1AK0 be used in static (fixed) cable installations as well as cable track?

Yes — a trailing-type cable is always suitable for static installation (the cable exceeds the requirements of a static application). The converse is not true: a static-type cable should not be used in a continuously moving cable track. For a static installation, both static and trailing types are acceptable; for a cable track, only the trailing type is appropriate.

Q3: What is the brake conductor (2×1.0mm²) rated for in terms of current?

The 2×1.0mm² conductors supply the motor's electromagnetic holding brake coil — typically requiring 0.5 to 1.5A DC at 24V to release the brake. The 1.0mm² cross-section is matched to this low brake current. The brake circuit uses a separate 24V DC supply, not the motor power supply — the conductor sizing is appropriate for the brake's DC coil load rather than the motor's AC power draw.

Q4: How does the 6FX2002 series relate to the newer 6FX5002 series cables?

6FX2002 is the earlier generation MOTION-CONNECT cable series designed for the SIMODRIVE 611 and older drive systems. 6FX5002 is the later generation designed for SINAMICS S120 and newer drives. Both use DESINA connector standards, but connector interface details and cable specifications may differ between generations. Always confirm the correct cable series from the specific motor and drive system's installation documentation.
