No−load startup compensation

When the elevator load is unknown, the system compensates the appropriate torque for the motor according to the running direction of the elevator, so as to make it start smoothly, minimize the car sliding at the moment of starting, and increase the comfort of elevator starting.

Special functions

Protecting anti−plug 

Perfect protection circuit design, any wrong insertion will not damage, and will not affect other controller.

Unique communication anti−interference

In order to improve the anti−interference performance, the car top board and the main control board use the enhanced CAN communication technology, without shielding wire.

Energy saving operation of standby power supply

When the normal power supply is interrupted and the emergency power supply is used, the system reduces the running speed of the elevator in the prerequisite of guaranteeing the smooth running curve and stop at the nearest floor.Open the door first, close door after delay for a period of time, press any key in the car to open the door.

Troubleshooting based on fault level

Faults are classified into different levels based on the severity. Different levels of faults are rectified using different methods, improving the system operation efficiency.

Auto−leveling

The system implements automatic accurate leveling based on the floor pulse counting and up/down leveling feedback signals.

Door pre−open function

In automatic running state, when the elevator speed is smaller than 0.25 m/s and the door zone signal is active, the system shorts the door lock by means of the shorting door lock circuit relay and outputs the door open signal, implementing door pre−open. This improves the elevator use efficiency.

Micro−leveling

After landing at a floor, the elevator may move upward or downward due to the load change and the car door is not aligned with the ground, which is inconvenient for passengers and goods in and out. In this case, the system allows the elevator to run to the leveling position in the door open state at the re−leveling speed.
