Common Issues with Yaskawa Drives
We regularly service issues such as:
-
Drive does not run the motor
-
Drive keeps blowing fuses or tripping breakers
-
Loose or damaged electrical connections
-
Cooling fan failures
-
Software or programming faults
-
Circuit board failures
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 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
When appropriate, we back up existing programs and run the drive through basic jog and motor tests to verify output performance, motor rotation, and overall operation.
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 trap heat and affect cooling performance.
Ensuring proper ventilation
Adequate airflow helps prevent overheating and supports reliable drive operation.
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, cooling 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.
