OTIS Elevator Lift Circuit Main Mother PCB Board Panel MCB3X PCB GCA26800KV4
Description of Elevator Lift Circuit PCB Board
The Function of Elevator main board
A control system includes light, machine, electricity, and calculation. The main board is mainly responsible for calculation, which is equivalent to the human brain. It collects the running state of the elevator, outputs the corresponding analog signal, and controls the correct and safe operation of the elevator.

The reason why the elevator circuit board is burned out,
The parameter setting of the inverter deceleration time is relatively small and the deceleration over voltage self-processing function of the inverter is not used. When the inverter drags a large inertia load, its deceleration time is set relatively small. During the deceleration process, the output frequency of the inverter decreases faster, but the load inertia is relatively large, and the deceleration is relatively slow due to its own resistance, so that the load drags The speed of the motor is higher than the speed corresponding to the frequency output by the inverter, the motor is in the power generation state, and the inverter has no energy processing unit or its function is limited, which leads to the increase of the intermediate DC circuit voltage of the inverter and exceeds the protection value. An over voltage trip fault occurs.
