A brief description of the selection of Delta inverters

1. The environmental requirements of the inverter Ambient temperature - 10 °C - 40 °C; Ambient humidity: The relative humidity does not exceed 90% (no condensation); Other occasions that require no direct sunlight, no corrosive gas and flammable gas, and less dust, with an altitude of less than 1000m. ...

1: What is the difference between servo motor and general motor? The biggest difference between servo motors and general motors is the motor rotor and reaction equipment. The surface of the servo motor rotor is pasted with a strong magnetic plate, so that the magnetic field generated by the stator coil can control the orientation of the rotor, and the acceleration and deceleration characteristics are ...

The capacity selection of the inverter is based on the rated power of the motor Myth: The capacity selection of the inverter is based on the rated power of the motor Compared with the motor, the price of the frequency converter is the most expensive, so under the premise of ensuring safe and reliable operation, the frequency conversion can be reasonably reduced.

When many engineers debug servo motors, they often have such a problem: why is my servo motor so slow, how can I improve the speed, and how much can the maximum speed reach? The basis for the confirmation of the speed method of the servo motor: the speed of the servo motor. ...

1. Use a vacuum cleaner with a plastic nozzle to completely clean the inside and outside of the inverter cabinet to ensure that there is no excessive dust around the equipment. 2. Check the ventilation and lighting of the inverter room, and the ventilation equipment can work normally. 3. Check the inverter ...

In general, factory motors are based on the additional speed values obtained at a given power frequency voltage (380 V, 50 Hz). If 380V is not reached under actual operating conditions, e.g. as long as 300V, 50 Hz, the voltage is significantly undervoltaged. Fundamentally, it cannot reach the extra rev value, due to the ...

The inverter of Delta's brand A series locks the keypad to correct the parameters, forming that most of the parameters cannot be corrected, and the manual does not clearly explain how to unlock the keypad lock, press MODE and RESET together to display P256 (P256 does not explain what it means in the manual), press ENTER...

The low-voltage fuse cannot be used as an overload maintenance for the motor. It is necessary that the additional voltage of the fuse is greater than or equal to the operating voltage of the distribution line. It is necessary for the additional current of the fuse to be greater than or equal to the additional current of the melt ...

Delta's VFD inverters have established extensive brand awareness in industrial automation stores. Each series of products is designed for different operating needs such as torque, loss, overload, overspeed operation, etc., and is adjusted according to the characteristics of different industrial machinery; It can provide customers with a variety of choices, and a wide range of ...

Delta-B series inverter inverter output module is damaged and the drive circuit is seriously damaged: the drive integrated circuit T250V or burst, or the output terminal and the power supply ground are short-circuited, the filter capacitor is sprayed, the regulator tube is broken down or open, the resistance is open or the resistance value increases, and the circuit board carbonization is damaged.

(1) When the speed of the motor is controlled by the Delta inverter, the noise and temperature rise of the motor are higher than that of the frequency of the motor. When the motor is running at low speed, because the speed of the motor blades is low, the temperature rise of the motor becomes high.

What is the stall prevention function of the inverter? If the given acceleration time is too short, the output frequency of the inverter changes much more than the change of speed, and the inverter will jump due to the flow of overcurrent, and the free operation is stopped, which is stalling. In order to prevent stalling and keep the motor working, ...

Delta inverters still have a certain influence in the industry, but even if the reputation is good, it will inevitably show some failures. Let's take a look. ...

With the continuous development of science and technology, there are more and more types of domestic machinery and equipment, and the upgrading of equipment is getting faster and faster. So what are the characteristics of two-phase electric fan inverter and whether it is worth choosing for enterprises. ...

Automatic: P0-02 Drive Status Display Parameter Function: 07Motor Speed (r/min) P1-01 Control form and control command input source setting parameter function: 02 Select S form (r/min) P1-38: Zero speed detection accuracy (no response below set speed) P1-4 ...

As we all know, the inverter has many maintenance functions, such as overcurrent, overvoltage, overload maintenance and so on. With the continuous improvement of industrial automation, frequency converters have also been widely used. This article will explain to you how to use a multimeter to measure the quality of the inverter. Need...

1. The welding station is actively handed over, and the operator has been loading and unloading parts in a fixed position, which effectively reduces the labor and logistics intensity of the operator, and the welding products of the whole set of equipment have strong compatibility and strong automatic welding scalability. 2. All ...

1. Common faults of motor heating up too high or smoke motor Causes: 1. Excessive load; 2. Two-phase operation; 3. Blocked air duct; 4. The working temperature is too high; 5. Interphase or inter-turn short circuit fault of motor stator winding; 6. Motor stator winding grounding device; 7. The power supply voltage is too high or too low; Overhaul...

Battery Management Solution Factory - Delta released the Mitsubishi Heavy Industries Group's star product, Mitsubishi Heavy Industries Group's three-power transformer hybrid one-power transformer system, proposing a high-quality method. This power transformer system is currently used at Mitsubishi Electric Manufacturing Plant in Aihara City, Kanagawa Prefecture, Japan.

(1) Ambient temperature: The inverter is the same as other electronic equipment, and has certain requirements for the ambient temperature, which is generally "-10-+40°C". Because the inverter is a high-power electronic equipment, it is easy to be affected by the operating temperature, but in order to ensure the safety of the inverter...
