Common Issues with Invertek Drives
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
-
Overcurrent faults and shutdown conditions
These issues can affect performance, reliability, and startup, and often require detailed testing of both the drive and connected motor system.
The Control Concepts Repair Process
Inspection
We inspect the drive and terminals for loose, worn, or heat-damaged connections caused by heat cycles, vibration, or improper torque.
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
We back up existing parameters when possible and test drive operation through basic run or jog functions. If the motor does not run properly, we verify output voltage, current ratings, and overall drive performance.
Final Verification
Each drive 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 free of dust and debris
Dust buildup can restrict cooling and affect internal components.
Ensuring proper ventilation
Adequate airflow helps prevent overheating and supports reliable drive performance.
Keeping drives 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, fans, and 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.
