SIEI Escalator-Specific Vector Frequency Converter Features
The Italian SIEI-specific elevator variable-frequency drives have been widely adopted in China’s elevator and crane industries for many years. Thanks to their excellent cost-performance ratio, they have won the favor of numerous users. For instance, they have been successfully applied in major elevator companies across China, such as Xizi Otis in Hangzhou, Bolinte in Shenyang, Andis in Xi’an, and Zhongxiu in Wuxi, as well as Best in Shanghai.
The Italian SIEI dedicated elevator VFD features powerful programmable functions.
1. Door zone position control and early door-opening function
After detecting the leveling light switch activation, the variable-frequency drive will decelerate according to the curve preset internally and come to a stop at the leveling point. At the same time, the output of the variable-frequency drive will enable the door bypass to conduct, allowing the elevator to open its doors ahead of schedule, thereby significantly improving the elevator’s operational efficiency.
2. Braking Feedback Detection Function
Whether the elevator is in standby mode or running, the variable frequency drive will monitor the brake status. Once it detects that the brake is in an abnormal state, the VFD will trigger an alarm.
3. Contactor Feedback Detection Function
Whether the elevator is in standby mode or running, the frequency converter will monitor the status of the output contactor. Once the contactor is detected to be in an abnormal state, the frequency converter will trigger an alarm.
4. Speed detection function
Once the inverter detects that the actual speed does not match the set speed, it will also disconnect the safety circuit and trigger an alarm.
5. Grid Voltage Fluctuation Detection
For a period of time, if the grid voltage experiences continuous fluctuations, the inverter will automatically trigger an alarm.
6. Pre-torque function
SIEI variable-frequency drives provide smoother elevator starts thanks to their torque output.
7. Power-off auto-leveling function
Elevator automatic leveling can be achieved using either UPS or DC power.
8. Motor self-learning or encoder positioning function
Motor self-learning or encoder positioning can be achieved without removing the steel wire rope or opening the brake.

SIEI (Westway) Technical Specifications of Vector Frequency Converters Dedicated for Escalators
1. Offline/Online Automatic Tuning: Self-tuning of speed, current, and magnetic field regulators and motor parameters (can be performed using both static and dynamic methods); motor parameters are automatically compensated according to temperature variations.
2. Torque Control: Through its built-in functionality, the system gradually communicates and controls between the speed and torque regulators, with an instantaneous overload capacity of up to 200%.
3. High-reliability protection: Thermal protection for the motor and driver at 12°C.
4. Rich parameter options: dedicated startup directory, 7 preset speeds, and 5 sets of independently programmable ramp curves, among others.
5. Excellent additional features: electronic potentiometer function, restart-on-run function, load-sharing function, PID module function, and power-failure detection and operation management.
6. Optimized control: Simulation and remote I/O management, as well as logical/mathematical operation functions for internal LINs.
7. Rich selection of optional modules: I/O expansion cards, auxiliary encoder management cards, fieldbus expansion cards, programmable cards, and safety protection cards.
