Common Issues with WEG Drives and Soft Starters
We regularly service issues such as:
-
Software or programming faults
-
Cooling fan failures
-
Loose or damaged electrical connections
-
Drive blowing fuses or tripping breakers
-
Drive not running the motor
-
Circuit board failures
-
Startup faults or soft starter performance issues
-
Overcurrent faults are a common cause of drive shutdowns, which is why troubleshooting should include the drive, motor, and connected operating conditions.
The Control Concepts Repair Process
Inspection
We inspect the drive, soft starter, and terminals for loose, worn, or heat-damaged connections, signs of overheating, vibration-related wear, or other visible issues that may affect performance.
Electrical Testing
We perform diode and IGBT testing on the input and output power sections before applying power to help prevent further damage from a short.
Controlled Power-Up
The unit is powered up gradually while monitoring amp readings and output frequency until rated input voltage is reached.
Functional Testing
When appropriate, we back up existing programs and run the drive through basic jog and motor tests to verify output performance and overall operation.
Final Verification
Each unit is fully tested to confirm proper operation before returning it to service.
Preventive Maintenance Recommendations
To reduce failures and extend equipment life, we recommend:
Keeping drives and soft starters free of dust and debris
Dust buildup can trap heat and affect cooling performance.
Ensuring proper ventilation
Adequate airflow helps prevent overheating and supports reliable operation.
Keeping equipment dry and protected from moisture
Moisture can damage internal electrical components and lead to corrosion or shorts.
Inspecting terminals and connections regularly
Routine checks can help identify loose or heat-damaged connections before they cause downtime.
Scheduling periodic testing and inspection
Regular inspection of power sections, control components, and overall operating condition can help catch problems early and reduce unexpected failures.
Preventive maintenance plays a key role in reducing unplanned downtime and extending equipment life.
