What is the difference between Developmental Coordination Disorder (DCD) and Dyspraxia? Developmental Coordination Disorder (DCD) refers to a condition in which a person has severe difficulties in learning everyday motor skills, which cannot be explained by physical, sensory or intellectual impairments. The main features of the condition are clearly described in DSM-5.
A variable-frequency drive (VFD) (also termed adjustable-frequency drive, variable-speed drive, AC drive, micro drive or inverter drive) is a type of adjustable-speed drive used in electro-mechanical drive systems to control AC motor speed and torque by varying motor input frequency and voltage.he VFD controller is a solid-state power electronics conversion system consisting of three distinct sub-systems: a rectifier bridge converter, a direct current (DC) link, and an inverter. Voltage-source inverter (VSI) drives (see 'Generic topologies' sub-section below) are by far the most common type of drives.
