AC Drive for Construction Elevator

The comfortability, safety and reliability of elevators have been improved through applying the internal advanced vector control with sensor and high accuracy intelligent control. The product is mainly used in passenger elevators and automated warehouse, ect.

Technical Features:
1. Compatible with synchronous and asynchronous motor;
2. Starting torque compensation of weighting sensor; easy parameter setting can prevent starting sliding;
3. Starting torque compensation control of non-weighting sensor; control synchronous gearless tractor elevator and start steadily;
4. Synchronization and accurate initial angle identification, for SM, autotuning and debugging simplifying are available in the state, especially for the debugging during the connection between motor and machine;
5. Optimized speed loop: the speed loop applies variable ratio and Integral gain control, provides high dynamic response for starting and stopping and improve the comfort when constant running;
6. Forced deceleration process: prevent shock in up/down running;
7. Emergency-running: stop at the nearest leveling.
