This file type includes high resolution graphics and schematics when applicable. Determine if a VFD is right for your application. The primary function of a variable frequency drive is to vary the ...
Variable-frequency drives (vfd’s) go by a number of different names, such as variable-speed drives, adjustable-speed drives, and adjustable-frequency controllers. It doesn’t really matter what you ...
A VFD reports a low-volts fault when the drive's dc link voltage drops below 62% of the nominal level for the high setting (480 Vac) and 50% of nominal for the low setting (400 Vac). The +10% and -15% ...
For retrofits Electro Static Technology’s AEGIS® Shaft Voltage Test Kit makes it easier than ever to measure and document damaging VFD-induced voltages while there is still time to head off bearing ...
