8.FAQ

Q1. The basics of variable frequency drive installation?

A1: Starting and stopping a motor can be done with three common methods: a motor starter, soft start or variable frequency drive (VFD). As of late, the use of a VFD is becoming more popular than ever due to its claimed efficiency benefits, but be sure it is needed. And, once specified, it must be properly installed to ensure reliable operation.


The VFD, often called an ac drive or inverter, takes a single- or three-phase signal and varies the speed of a three-phase ac induction motor. This is its main benefit. Running a motor more slowly can save significant energy, and speed changes may be useful to the application. Another big benefit is adjustable acceleration and deceleration. Less acceleration can soften the mechanical forces at motor start and reduce inrush current. The VFD also has built-in overload protection and motor start/stop control functions.


Electrically, proper run/stop control of the VFD is important. Many manufacturers do not recommend using contactors or disconnect switches on the line or load side of a VFD for run/stop control of the ac drive and motor, except for emergency situations. Opening a contactor at the line or load side of a VFD while the motor is running can cause failures in the inverter section of the drive or reduce its life. Even if it doesn't cause failure, it can take several seconds for a VFD to power on once power is applied.
