Italy SIEI special elevator inverter has been promoted in China's elevator industry and crane industry for many years, because of its excellent cost performance has also been favored by many users, such as in China's Hangzhou Xizi Otis, Shenyang Bolint, Xi'an Andis, Wuxi Zhongxiu, Shanghai Best and other large elevator industries have been successfully applied.
Italy SIEI dedicated elevator inverter has powerful programmable functions
1. Door area position control and early door opening function
After the inverter detects the leveling photoelectric action, it will decelerate and stop at the leveling point according to its internally set curve; at the same time, the inverter output will make the door bypass conductive and the elevator will open the door in advance, greatly improving The efficiency of the elevator operation.
2.Brake feedback detection function
Regardless of whether the elevator is in standby or running state, the inverter will detect the brake status. Once the brake is found to be abnormal, the inverter will alarm.
3. Contactor feedback detection function
Whether the elevator is in standby or running state, the inverter will detect the state of the output contactor. Once the contactor is found to be in an abnormal state, the inverter will alarm.
4.Speed detection function
Once the inverter detects that the actual speed does not match the given speed, it will also open the safety circuit and issue an alarm.
5. Grid voltage fluctuation detection
In a period of time, if the grid voltage fluctuates continuously, the inverter will alarm automatically.
The SIEI inverter has a torque output, which makes the starting of the elevator more comfortable.
7. Power-off self-leveling function
Elevator automatic leveling can be achieved with UPS or DC
8. Motor self-learning or encoder positioning function
Motor self-learning or encoder positioning can be realized without removing the wire rope and opening the brake.
