Siemens 6SL3350-6TK00-0EA0 | SINAMICS Control Interface Module (CIM) — Spare Part for Air-Cooled Drives

Part Number: 6SL3350-6TK00-0EA0

Manufacturer: Siemens AG (Germany)

Product Type: CIM — Control Interface Module (Spare Part) 

Inside the Drive's Communication Bridge

The 6SL3350-6TK00-0EA0 is the Control Interface Module (CIM) for air-cooled SINAMICS drives — the internal assembly that connects the drive's power section to its Control Unit via DRIVE-CLiQ. It transmits PWM switching commands from the Control Unit to the power semiconductors, returns current and temperature measurement data, and manages the electronic nameplate handshake that identifies the module to the drive system.

The 24VDC / 3A output confirms the CIM also distributes control-level power within the drive chassis. Its 4.5 kg weight reflects a multi-board assembly with internal connectors and signal conditioning components — not a single PCB card. Replacement involves access to the drive's internal chassis and reconnection of multiple cable assemblies.

Key Specifications

FAQ

Q1: The drive shows F30600 or a DRIVE-CLiQ topology error. Could the CIM be the cause?

Yes. A failed CIM disrupts DRIVE-CLiQ communication between the power section and Control Unit. The drive cannot complete its topology scan, triggering F30600 or similar faults. Check the DRIVE-CLiQ LED on the CIM — steady green is normal; red or unlit indicates a fault.

Q2: Is there a separate CIM for liquid-cooled SINAMICS drives?

Yes. Siemens produces distinct CIM variants for liquid-cooled and air-cooled configurations. Confirm the drive's cooling method from its rating plate before ordering — fitting the wrong variant will not work.

Q3: Does replacing the CIM require drive recommissioning?

No. The CIM holds no drive parameters. After replacement, the Control Unit reads the new module's electronic nameplate via DRIVE-CLiQ and automatically identifies it. No parameter re-entry is needed.

Q4: The drive failed during a mains surge. Should anything else be checked before fitting a replacement CIM?

Yes. Check the Control Unit's 24V power rail after fitting the new CIM. A severe surge can damage both the CIM and the Control Unit simultaneously. If DRIVE-CLiQ errors persist after CIM replacement, investigate the CU.

Q5: The CIM weighs 4.5 kg. What does that mean for the installation procedure?

It indicates a substantial multi-board assembly. Replacement requires methodical disconnection of multiple internal cables and bus connectors. Follow Siemens' service documentation for the specific drive model to ensure connectors are re-seated in the correct sequence.
