can you set the speed on a variable speed driver
Adjustable speed drive (ASD) or variable-speed drive (VSD) describes equipment used to control the speed of machinery.Many industrial processes such as assembly lines must operate at different speeds for different products.here speeds may be selected from several different pre-set ranges, usually the drive is said to be adjustable speed. If the output speed can be changed without steps over a range, the drive is usually referred to as variable speed.
