Q1: What is the Siemens 6SL3352-6TG31-5AA3?
It is a Control Interface Board (CIB) replacement spare part for SINAMICS S120/S150 chassis drives. It sits between the Control Unit and the IGBT power stage, managing gate drive signals and current feedback .
Q2: Is this product still available from Siemens?
No. It is listed under PM490: Start of final year of support, indicating it is in the final phase of its lifecycle . It is available only through the industrial aftermarket.
Q3: What is the voltage class of this CIB?
It is designed for 3 AC 500–690 V motor modules. The "TG" prefix in the part number identifies the 690 V class .
Q4: Does replacing the CIB require re-parameterization?
No. The CIB does not store drive parameters—all configuration resides in the Control Unit (CU). After replacement, the drive reads its parameters from the CU and resumes operation without re-commissioning .
Q5: What fault might indicate a failed CIB?
F30021 (IGBT overcurrent) at standstill can be caused by a failed current measurement circuit on the CIB. Check whether phase current displays non-zero values at standstill as a diagnostic step .
Q6: How do I confirm the correct CIB part number?
The correct CIB is specific to the current rating of the Motor Module. Check the Motor Module type plate and cross-reference the Siemens spare parts documentation for that exact module variant. Do not rely on voltage class alone .
Q7: What are the net weight and country of origin?
Net weight is 0.400 kg . Country of origin is Germany .
Q8: What should I verify before ordering?
Always verify the exact part number (6SL3352-6TG31-5AA3), confirm the Motor Module current rating matches this CIB variant, check the condition and warranty of the specific unit offered, and ensure the supplier has experience with SINAMICS chassis drive components.
