Advantages of sensorless vector control - Delta inverter

1. Install AC reactor and DC reactor. When the capacity of the inverter is greater than 500kva in the distribution transformer, and the transformer capacity is more than 10 times the capacity of the inverter, an AC reactor is installed on the input side of the inverter. And when the output voltage of the distribution transformer is unbalanced and uneven in three phases ...

Low-voltage circuit breakers, commonly known as active air switches, are one of the primary electrical switches in low-voltage distribution networks. It can not only turn on and off normal load current, motor operation current and overload current, but also turn on and off short circuit current. It is mainly used as a low-voltage distribution line or a switch cabinet that is not often operated ( ...

1. The rated current of the inverter is low As mentioned above, when the rated current of some inverters is less than the rated current of the motor of the same capacity, the inverter with a larger gear should be considered according to the load condition of the motor. 2. The motor may be overloaded for a short time Since the electric motor ...

Reactors are also called inductors, and when a conductor is energized, a magnetic field will be generated in a certain space scale occupied by it, so all electrical conductors that can carry current have inductance in a general sense. However, the inductance of the energized long straight conductor is small, and the magnetic field generated is not strong, so the actual reactor is conductive.

1. VFD-B series This series has a variety of communication voltage standard model options, in addition to providing a variety of I/O signal functions, and can supply the appropriate current and voltage vector value according to the external load torque, to meet the needs of customers with high quality and low price. ...

Fault 1: Overcurrent in acceleration Clarification: Overcurrent in acceleration Solution 1: Check whether the wiring from U-V-W to the motor is poorly insulated; 2: Increase acceleration and deceleration time; 3: Replace the inverter with a larger output capacity; 4: Reduced (P54) torque ...

The external use resistor is an external operation form of the inverter, which controls the inverter through the external operation signal generated by the external starting switch and frequency setting potentiometer. The regular external voltage signal of different inverters is different. ...

If the inverter is to run the equipment again after being shelved for more than half a year, the probability of damage may be greatly increased due to many factors such as the placement environment, the service life of the inverter, and the load rate, and the failure usually presents the following problems: ...

1. One is a triode type photocoupler, such as PC816, PC817, 4N35, etc., which is commonly used in the output voltage sampling and error voltage amplification circuit of the switching power supply circuit, and is also used in the digital signal input loop of the inverter control terminal. The structure is the simplest, and the input side consists of a light-emitting two...

1. The motor is broken shaft 1. The cause of the problem (1) Unreasonable mechanical design leads to excessive radial load force; (2) The load end is stuck or severely overloaded; (3) The motor and reducer are not centered when installed. 2. Eliminate problems (1) Check the ...

1. Harmonic problems The equipment that plays the role of switching in the main circuit of the inverter must generate harmonics in the process of turning on and off the circuit. The lower harmonics generally have a greater impact on the motor load and cause torque ripple; The higher harmonics increase the leakage current of the inverter's output cable, making ...

1. Speed regulation of general motor: By changing the input voltage and frequency of the three-phase asynchronous motor, its speed can be controlled. Generally, when the motor is at low speed, the temperature rise becomes larger due to the decrease in the power of the cooling fan, and the motor load should be reduced according to the frequency. 2 ...

Delta's servo motor system is planned for industrial use, and it is necessary to have a sufficient understanding of the motor standards and operation manuals before operating the motor. For the safety of the operator and equipment, and to ensure that the motor can be used correctly, please read this safety precaution carefully before installing the machine. ...

input/output reactor for frequency conversion speed regulation; Because the inverter is often affected by the impact of inrush current and surge voltage in the process of driving the inverter motor operation governor, which will seriously damage the function and service life of the inverter and the motor, so it is necessary to install a transmission system in front of it.

　　Delta's frequency modulator frequency modulation is mainly operated on the control panel, and the process: 1. Press the Menu button to enter the parameter programming menu, 　　​ 　　2,P0.01=1,Enter this parameter to complete the correction frequency of the panel button, ...

The soft starter is a device used to control the start and stop of the motor, which is composed of a number of components, including the soft starter controller, the soft starter conditioner, the soft starter power supply, the soft starter input and output module, the soft starter interface module, etc. ...

There are many setting parameters of the inverter, and each parameter has a certain selection scale, and the inverter can not operate normally due to the improper setting of a single parameter is often encountered in the application, therefore, the relevant parameters must be correctly set. ...
