SIEMENS 6SL3350-6TK00-0EA0 – Drive Control Module | SINAMICS S120 Platform
Engineering Background: The SIEMENS 6SL3350-6TK00-0EA0 (board revision A5E02144966) is a factory-original Drive Control Module (DCM) designed for the SINAMICS S120 modular drive platform. SINAMICS S120 is Siemens’ flagship multi-axis servo and vector drive architecture, widely deployed in precision manufacturing, CNC machining centers, robotics, and high-dynamic motion control applications worldwide.
Product Positioning: This module serves as the central intelligence unit within the S120 drive system, coordinating closed-loop speed and torque control, DRIVE-CLiQ topology management, and real-time communication with higher-level SIMATIC PLC controllers. It is the authoritative replacement or spare part for OEM machine builders and end-user maintenance teams requiring exact form-fit-function compatibility.

- Long Service Life: Siemens industrial-grade components rated for continuous 24/7 operation in demanding factory environments.
System Architecture & Signal Flow
Within the SINAMICS S120 booksize topology, the 6SL3350-6TK00-0EA0 interfaces as follows:
- Upstream: Receives setpoints and safety commands from SIMATIC S7 PLC via PROFIBUS DP or PROFINET IO.
- Internal: Executes closed-loop vector or servo control algorithms at high sampling rates; manages DC bus energy exchange between Motor Modules.
- Downstream (DRIVE-CLiQ): Communicates with Motor Modules, Sensor Modules (SMC/SME), and Active Line Modules for real-time feedback and synchronization.
- Safety Channel: Dedicated fail-safe signal path for STO/SS1 functions independent of the main control channel.
Sourcing & Quality Verification
- All units sourced from authorized industrial distributors or verified OEM surplus channels.
- Each module undergoes visual inspection, label authenticity check (hologram, MLFB barcode), and functional power-on verification prior to dispatch.
- Serialized traceability records maintained for every shipment.
- Packaging: original Siemens ESD-safe anti-static bag + foam-lined export carton.

Technical FAQ
Q: Is 6SL3350-6TK00-0EA0 compatible with SINAMICS S120 CU320-2 DP/PN?
A: Yes. This Drive Control Module is designed to operate within the S120 ecosystem and is compatible with CU320-2 series Control Units subject to firmware version alignment.
Q: Can this module be used as a direct replacement for a failed unit without re-commissioning?
A: In most cases, yes — provided the replacement unit carries the same MLFB and the drive project file (STARTER/TIA Portal) is re-downloaded to the new module. DRIVE-CLiQ auto-detection handles encoder and motor data automatically.
Q: Do you provide the Siemens firmware file for this module?
A: We can advise on the correct firmware version. Firmware files are available through Siemens Industry Online Support (SIOS) under your Siemens account.
Q: What is the lead time for stock items?
A: In-stock units ship within 1–2 business days. For non-stock items, typical lead time is 5–15 business days depending on sourcing channel.
Q: Is a test report available?
A: Yes. A functional test report can be provided upon request for units that have undergone our pre-shipment verification process.
