Capacitor Reforming Procedure
Spare drives sitting on your shelf longer than a year may need to have the caps reformed. The capacitors need to be reformed (re-aged) if the drive has been non-operational for more than one year. The longer a VFD sits without external power, the more rigorous the reforming of the capacitors.

For 220-230V and 380-480V models apply supply voltage of approximately 220Vac, three-phase or single-phase input, 50 or 60 Hz, without connecting a motor to the output. This voltage should be applied for a period of 1 hour. After this energizing process, a wait period of 24 hours before installing or utilizing the drive for motor control is vital. Part of the oxide insulation is formed during this “resting” period. For 500-600V, 500-690V and 660-690V models use the same procedure applying a voltage between 300 and 330Vac to the inverter input.

Load Testing Procedure
Before you receive your drive, verifying its operational integrity is the key to ensuring proper operation and a long service life. We provide full functional load testing, identifying, and repairing failure modes, fully exercising output modules and complete testing of overcurrent circuits to guarantee your motor will spin to capacity when installed. Our staff of drive engineers are industry professionals that have worked with every brand and type of drive, from Allen Bradley and GE to Siemens, Danfoss, and many others.
