This variable speed/frequency drive (VSD/VFD) is designed for simple industry and commercial machines and appliances, such as conveyors, pumps, extractors, access barriers and treadmills. Its slim footprint allows for mounting within frames of simple non-industrial appliances. It can be configured before while still in its packaging without even using a power supply, thus minimizing installation time. So move software compatibility enables saving and transferring of configurations to spare drive, reducing maintenance downtime.
