STEP elevator integrated controller is an all-in-one controller and drive concept pioneered. The solution reduces cost and enhances reliability, and is suitable for passengers, freight and private residential elevators, as well as escalators and peripheral elevator devices. Key benefits include a small footprint; a single programming interface; fast, easy set-up; ride comfort with time-efficient direct landing, and enhanced safety. Prefect integration of control and drive of elevator leads to compact structure, few wiring, high reliability, easy operation and cost efficiency Double 32-bit MCU combines the elevator control and motor control Redundant safety design , double safety protection for control and drive CAN bus communication make the whole system easily, fast and reliable. Support traditional group control and destination dispatching control Support one main contactor solution Support gear and gearless motor Use PIM module, lower loss in switch on and off and longer lifetime, Creative Zero-speed torque compensation technology provides the elevators with good starting ride quality without installing weighing devices Close-loop vector brings higher performance in control New PWM dead-zone compensation technology brings less energy loss Dynamic PWM carrier modulation technology brings less motor noise
