FST-100 Door crane dedicated frequency converter

The FST-100 series door controller is a specialized variable frequency door drive controller for elevator doors, cold storage doors, subway doors, and other door systems. It integrates door opening and closing logic control and motor drive control. The external system only needs to provide door opening and closing commands to achieve control of the entire door system. This controller can drive AC asynchronous motors and permanent magnet synchronous motors, and supports two modes: speed control and distance control. The product has a wide range of applications and can meet the control and driving needs of most door systems.
