. ◆ Provide overload, Various alarm functions
such as abnormal parameter setting ◆ With automatic adjustment of carrier frequency function, more stable and reliable
operation ◆ With speed tracking and restart function: to achieve smooth start
without impact on the rotating motor ◆ With automatic voltage adjustment function, it effectively solves the problem of low-frequency oscillation of
high-power motor ◆ It has the function of instantaneous power loss without
◆ 0.75~22kW built-in brake unit in each specification, if you need to stop quickly, you can directly connect to the brake resistor
◆ Self-learning function: completely solve the problem of unsatisfactory vector control, can give full play to the motor function
◆ V/F curve: There are 15 kinds of V/F curves for users to choose from, and they can also be customized by users V/F curve
◆ PID proportional, integral, differential control: it can realize the speed control using pulse generator and other speed detectors, independent of load and keep the speed consistent or synchronous operation with other motors; The flow sensor is used in flow control, which can be applied to flow situations with high control accuracy requirements. During pressure control, the detection value of the pressure detector is used as a feedback quantity to ensure that its pressure is constant; During temperature control, the temperature detector detection value is used as feedback, so that the fan speed can be changed to the predetermined control requirements

◆ DWELL (pause) function: the output frequency is maintained for a certain period of time during acceleration and deceleration, and then the acceleration and deceleration action is performed. In loads with large inertia, such as lifting machinery before lifting heavy objects, the wire rope of the hook is usually in a relaxed state, and after the pause and acceleration function is preset, the wire rope can be tightened first and then raised; Some machinery is easy to solidify the lubricating oil at low ambient temperature, so it is required to run at low speed for a short time to dilute the lubricating oil and then accelerate; For the electromagnetic brake motor with mechanical brake device, in order to reduce the friction between the brake skin and the brake roller during the release of the magnetic brake, it is required to run at low frequency first, and then increase the speed after the magnetic brake is completely released

◆ Low noise design: The output loop adopts an insulated base bidirectional transistor and a high carrier frequency sine wave PWM method, which greatly reduces the metal of the motor

Sound
◆ Real-time monitoring function: it can monitor the output frequency, output current, motor speed, output voltage, DC bus voltage, output power, and output force
