Product overview

The series of BD 550 high-performance inverter adopts the advanced Flux current vector control technology of Anchuan Motor, which  is equipped with various kinds of advanced applications such as speed control, torque compensation, slip frequency compensation, energy-saving control, revolving speed tracking and self-learning that can meet the demands of customers of different industries.

Product features
Suitable for high-end situations such as high precision, quick response, high torque, large inertia, and potential load.
Perfect self-learning function, and ultra-low speed  high starting torque. It can output 150% rated torque when the speed in closed loop vector control status is 0.

RS-485 communication interface is optional. And it completely support MODBUS communication protocol.
Provided with protection function for many malfunction: overcurrent, overvoltage, undervoltage, overheating, default phase and overload, etc.

Self-learning function: completely solve the unsatisfactory problem of vector control and give full play to the performance of motor.

V/F curve: 15 V/F curves, and user-defined V/F curves are available for users.

DWELL (pause) function: the output frequency keeps constant within certain time during the acceleration and deceleration process, and then proceed the acceleration and deceleration motion again. In cases of load with large inertia, such as before hoisting machinery slings weight, the wirerope of lifting hook is generally in loose status. After presetting acceleration pause function, firstly, tensioning the wirerope before lifting; in cases of low environment temperature, the lubricating oil of some machines are easy to freeze, thus it's required to run with a low speed for a short time, and then accelerate after the lubricating oil dilutes; for those electromagnetic braking motors with mechanical braking equipment, during the loosening process of magnetic brake, it's required to run at a low frequency for the purpose of reducing the friction between braking rubber and braking club. Accelerate after the magnetic brake totally loosens.
