A leading beverage manufacturing company experienced an input phase loss fault on a 250kW ABB ACS880 Variable Frequency Drive, resulting in the equipment being unable to operate reliably. As the drive formed part of a critical production process, immediate technical intervention was required to minimize operational downtime.

The drive was subjected to a comprehensive diagnostic assessment Team Teknifix. Detailed inspection of the power section identified multiple defective components. These components were confirmed to be the root cause of the input phase loss condition.

Team Teknifix replaced all faulty components with compatible OEM-grade parts before carrying out functional testing to verify stable operation and ensure compliance with manufacturer performance standards.

The project included:

• Continuity testing to ensure no short circuit between positive and negative terminals
• Comprehensive physical inspection of internal components and electrical connections
• Diagnosis of input phase loss fault within the power section
• Replacement of faulty components with OEM-certified spares
• Functional testing and operational verification of the drive

The work was completed successfully within schedule, restoring the drive to full operational condition and enabling the client to resume production with minimal disruption.
