The Undervoltage warning of the inverter is judged based on the voltage of the main circuit as follows. Power failure only at the main circuit: Output an Undervoltage warning power failure only at the control circuit. Not output an Undervoltage warning when the...

If using an inverter with a capacity of 75K or higher, or a motor with a capacity of 75 kW or higher, always select and install the inverter based on the capacity of the motor with a DC reactor.

Nothing. Both terms are used for describing drive inverters. They are prominently being used interchangeably, depending on the manufacturer of the country. (For Mitsubishi FA, the term VFD is mostly used.). VSD (Variable Speed Drive) refers to the motor shaft...

In one word, no. A VFD cannot be used as a replacement for a voltage transformer. If a motor requires 400Vac, then a 400Vac source is required as an input to the 400Vac VFD. The same goes for other voltage classes, The only exception to this rule is with phase number....

There are 4 classes for duty classification purposes. They are: SLD – Super light duty. (startup current: 110% for 60sec and 120% for 3sec – of the FLA value) LD – Light Duty (startup current: 120% for 60sec and 150% for 3sec – of the FLA...

kW (power) alone is not sufficient. One requires the motor nameplate details and the application details. From the motor nameplate, we can find the FLA current, voltage, phase number. From the application details we can determine the duty requirements of the inverter...
