The equipment was received in an inoperative and visibly dirty condition.

A careful disassembly was performed for a detailed visual inspection.

The technical analysis identified a fault in the IGBT (Insulated Gate Bipolar Transistor), a critical component for power conversion.

The circuit boards underwent a thorough general cleaning to remove dirt and debris that could cause overheating and future failures.

The damaged component (IGBT) was replaced with a new part, ensuring the integrity of the power circuit.

After reassembly, the inverter underwent a series of rigorous bench tests. The ATV312 drive was configured using the SoMove software.

The final test was performed directly on a motor, validating the inverter's functionality and correct frequency conversion.

The equipment was approved, operating efficiently and within factory specifications.
