The V3F20 is a typical VVVF drive unit combined with an external capacitor soft-start module.

The drive is often conjoined with the Kone TMS processor. Also, the V3F20 drive controls a 3-phase geared induction motor with DC tacho feedback. This gives you precision control. Moreover, the V3F Green Power controller includes many inputs that allow the drive to control an elevator (lift) application in an industrial or commercial setting.

The drive is either low or mid-range geared V3F for a TMS control system. It is a 400 V drive with 3 current ratings:
