Maintenance and Testing

Preventive Maintenance and Testing of a Variable Frequency Drive (VFD) 

• Equipment: Danfoss VLT-5016 Variable Frequency Drive.

• Actions: I performed scheduled preventive maintenance on the VFD to ensure its reliable operation and to prevent potential future faults.

• Testing: As part of the maintenance, I conducted functional tests by simulating various loads. The motor was tested with both star (Y) and delta (Δ) connections to verify its performance and ensure optimal efficiency under different operating conditions.

• Result: The VFD was confirmed to be in optimal condition, securing continuous motor speed control and maintaining the full functionality of the system, thus preventing unscheduled downtime.
