Elevator Component lift Inverter Drive VVVF AS320

الوصف

Features:
AS**0 series is a new generation of elevator specialized inverter, which is developed  based on elevator driving performance. It applies **-bit MPU to drive inverter type motor, applies programmable and Super-scale logical component-CPLD, and the most advanced power module with closed-loop-vector control technology, compatible for voltage-vector V/F, vector SVC Open loop and the torque control pattern, and integrates the features of potential energy load model to achieve a comfortable ride and improve the efficiency.

Technical Characteristics:
Innovative startup compensation technology without load sensor to ensure comfort feeling at the starting moment without need of installing the weighting device;
Incremental ABZ encoder to realize the control of synchronous motor and startup compensation technology without load sensor to ensure comfort feeling at the starting moment;
New PWM dead-zone compensation technology to effectively reduce motor noises, save energy;
Dynamic PWM carrier commissioning technology to effectively reduce motor noises;
No need of self-tuning for synchronous motor but automatic identification system to get the phase angle of encoder,
No need of self-tuning for asynchronous motor when setting up right paremeter of motor; If the exact parameters can not be accessed at job site, they can be got by inverter automatically by means of simple and static self-learning without need of other complicated job such as lifting car;
Sixth generation of new-type module used for hardware, with junction temperature resistance at maximum **5°C and low consumption of power and energy;
