The KEA26800ABS8 is a dedicated inverter drive board for Otis elevators, belonging to the core control component of the inverter. Its main functions are as follows:
* **Receive Main Control System Commands:** Receives operating commands from the elevator mainboard/inverter CPU, including signals for elevator start, acceleration, deceleration, leveling, and stop, acting as the inverter's command execution unit.
* **Drive IGBT Power Modules:** Outputs drive signals to control the on/off state of the IGBTs and power modules within the inverter, achieving the conversion between DC and three-phase AC power to provide stable power to the elevator motor.
* **Regulate Elevator Motor Speed ​​and Torque:** By precisely controlling the output voltage, current, and frequency, it adjusts the speed, torque, and operating curve of the elevator traction motor, ensuring smooth elevator start-up, quiet operation, and precise stopping.

Real-time monitoring and feedback signals: Operating parameters such as current, voltage, and temperature are collected in real time and fed back to the inverter control system to achieve closed-loop regulation, ensuring stable and reliable motor operation.

Protection functions: Monitoring and controlling abnormal states such as overcurrent, overvoltage, undervoltage, overload, overheating, and short circuits. In the event of a fault, the drive signal is immediately blocked to protect the power module, motor, and inverter from damage.

Ensuring safe and stable elevator operation: As the core drive hub of the inverter, it directly determines the comfort, smoothness, and safety of elevator operation, and is a key electronic component for the normal operation of the elevator.
