Variable Frequency Drives (VFD’s), also referred to as Adjustable Speed Drives, are prominent in today’s workplace. Motors running at constant speed generate full flow of air , but to reduce the flow we are using dampers , we are using full energy of motor and using low output air flow this causes waste of energy , so we use Vfd for air flow control. The IGBTs have inside an antiparallel diode, so it helps with the measurments as well. at the beginning we thought the VFD was faulty then we replaced with a new one. Check For Shorted IGBT. Now you need to perform the same test for the B+ side of the VFD. The CPX series of variable frequency drives uses advanced 18-pulse clean power technology that significantly reduces line harmonics at the drive input terminals—resulting in one of the purest sinusoidal waveforms available. The student will also receive an electronic copy of the. Check for and correct: † A short-circuit in the motor cable(s) or motor. A variable-frequency drive is a device used in a drive system consisting of the following three main sub-systems: AC motor, main drive controller assembly, and drive/operator interface. These components may have failed if the drive input fuses or circuit breaker opened, or the drive keypad. † Obstructions in the air flow. Switch the probes. 3*600=180 V if the DC voltage is 600 V. The device must be able to clear a fault quickly enough to minimize damage to the drive or soft starter. If the duty cycle is 60%, the mean voltage will be 360 V).
