Our Repair Process for the
6DS1621-8AA
Our repair process begins with a comprehensive diagnostic evaluation to pinpoint the root cause of the Siemens 6DS1621-8AA failure. We address capacitor degradation in the power supply by replacing all electrolytic capacitors with high-quality, extended-life components to ensure voltage stability. IGBT failures in the inverter section are resolved through replacement with matched, high-performance IGBTs, accompanied by thorough testing of the gate drive circuitry. Communication errors stemming from the PROFIBUS interface are rectified by repairing or replacing damaged connectors, verifying correct termination, and, if necessary, replacing faulty communication processors. Encoder feedback problems are corrected by repairing or replacing damaged encoder cables, resolving resolution errors, or replacing defective encoder modules. Firmware corruption is resolved by reflashing the device with the correct firmware version, followed by rigorous testing to confirm proper operation.
