Designed around the operating characteristics of elevator traction systems, the GK620E Elevator Dedicated AC Drive provides dedicated motor control for passenger and freight elevators. As an elevator AC drive, GK620E supports open-loop operation, smooth S-curve acceleration and deceleration, and elevator-specific control functions to improve ride comfort and leveling performance.
The drive supports power ranges from 3.7 kW to 30 kW and is designed for integration with elevator control units, main contactors, brake contactors, and traction motors. Its simplified parameter configuration, preset emergency maintenance mode, and fault diagnosis functions help streamline installation, commissioning, and maintenance.
With its dedicated control algorithms and integrated brake unit, the GK620E elevator VFD can be applied to passenger and freight elevator systems in residential buildings, shopping malls, office buildings, and other commercial buildings.
The GK620E elevator control solution combines a dedicated AC drive for elevators with the elevator control unit, traction motor, contactor control, and braking circuit to provide coordinated control of elevator movement.
In the system, the control unit sends operating commands such as upward, downward, enable, and emergency-speed signals to the GK620E. The drive then controls the elevator motor through the U/T1, V/T2, and W/T3 output terminals, while the main and brake contactors provide corresponding motor and braking control.
This drive-centered architecture allows the elevator motor control system to coordinate starting, acceleration, deceleration, leveling, inspection operation, and fault output according to the elevator control logic.
The GK620E elevator drive is designed for elevator applications where stable motor control, smooth acceleration and deceleration, and simplified commissioning are required.
For passenger elevators in residential and commercial buildings, the elevator AC drive provides smooth speed transitions and flexible S-curve control to improve ride comfort during starting, running, and stopping.
For freight elevator applications, the drive provides strong torque performance and stable motor control for elevator systems transporting goods and equipment.
GK620E can be used in elevator systems installed in:
The following system diagram illustrates how the GK620E Elevator AC Drive interfaces with the elevator control unit, AC power supply, traction motor, main contactor, brake contactor, and braking components.
The control unit provides key commands including Enable, Upward, Downward, Emergency Speed, High Speed, Low Speed, and Inspection Speed. GK620E processes these commands and controls the elevator motor accordingly.
The system also provides fault output and contactor control interfaces, allowing the drive to communicate its operating status with the elevator control system.
The control architecture includes:
This configuration makes GK620E suitable for integration into an elevator control system where coordinated motor, speed, braking, and fault control are required.
GK620E is designed to work with an external elevator control unit rather than functioning only as a standalone general-purpose motor drive.
The control interface shown in the system diagram includes:
Control Inputs
Status and Output Signals
This interface structure allows the elevator motor control and elevator control unit to work together, while the drive manages the motor speed and torque according to the commands received from the control system.
The GK620E Elevator Dedicated AC Drive is designed for passenger and freight elevators in residential, commercial, and office buildings. It supports sensorless vector control, flexible S-curve operation, high starting torque, and elevator-specific functions for smooth motor control and simplified commissioning.
