EMC Filter Installation Considerations – Delta

After the inverter is installed, disconnect the output of the inverter, use the diode file of the digital meter to measure the input and output of the inverter before the power is not turned on, ensure that there is no short circuit, and then turn on the working power supply of the inverter.

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. After the equipment is powered on, it becomes ...

The thermometer method and resistance method can be used to measure the temperature rise of each part of the reducer. 1) Thermometer method: This is the easiest way to measure the temperature directly, and it is commonly measured by an alcohol thermometer. When measuring, the thermometer can be placed close to the ...

Delta's thermostat is a commonly used temperature control device, which can adjust the temperature according to the user's needs, and then achieve the intention of saving energy. The effect and use of Delta thermostats are also very widespread, so let's introduce the effects and uses of Delta thermostats. ...

Industrial control automation products inverters are depicted as power-saving, energy-saving control automation products, therefore, many people will think that as long as the equipment is installed with inverters, it will be able to save energy, but this is not the case. The inverter of industrial automation products itself produces energy-saving ...

1) When taking out or placing the servo motor, it is not possible to only pull the wire and drag the motor or only hold the rotating shaft core. 2) Do not hit the shaft directly, e.g. by tapping or hammering, as this may cause damage to the shaft and the encoder attached to the opposite side of the shaft. 3) Give the shaft core ...

With the increasing demand for system switching power supply by computer technology, Delta UPS uninterruptible power supply R-2K series products have been paid more and more attention, and gradually developed into a kind of electrical engineering with the effects of voltage stabilizer tube, frequency stabilization, filtration, anti-electromagnetic and frequency emission influence, anti-operation voltage swimming, etc.

The inverter is the pioneering work of Delta Automation, and it is also the largest selling product of Delta Automation. In the highly competitive market, Delta inverters have always maintained a strong growth momentum and made great achievements in the high-end product market and the economic product market. Delta continues to launch high-end products ...

1. Set temperature: Press the SET button to set or view the temperature set point. Press the SET key digital tube character beginning flash, indicating that the appearance has entered the setting state, press the △ key to increase the set value, press the ▽ key to decrease the set value, press and hold the △ key or ▽ key The data will change rapidly, press the SET key again The appearance back ...

1. Overvoltage The output of the inverter has the function of voltage detection, and the inverter can actively adjust the output voltage so that the motor does not withstand overvoltage. Even when the output voltage adjustment fails and the output voltage exceeds 110% of the normal voltage, the inverter will be shut down and the motor will become infected. ...

Delta's Ultron HPH series UPS has an AC-AC efficiency of up to 96%, and can reach 99% in ECO mode, with significant energy savings. The flexible airframe provides a compact footprint (40kW / 0.15 m2) and reduces space waste. With an interface-friendly 5-inch colorful touch screen, ...

Daily inspection item 1 of Delta's inverter problem repair: Check whether there is any abnormal change in the sound of the motor during operation, including whether oscillation occurs during the operation of the motor. Delta's daily inspection of inverter problem repair ...

1. Visually inspect the UPS and battery (or other energy storage) equipment for obstacles, and properly cool the surrounding area. 2. Ensure that there is no abnormal operation or positive warning on the UPS panel, such as: overload or overdischarge of the battery close to it. 3. Check if there is battery corrosion or other shortcomings ...

Delta's VFD series of inverters has established a wide brand awareness in the industrial automation market. Each series of products is designed for different operation needs such as torque, loss, overload, overspeed work, etc., and is adjusted according to different industrial machinery attributes; It can provide customers with the most diversified choices ...

1. The inverter must be selected correctly. 2. Read the product manual carefully, and wiring, device and application in accordance with the requirements of the manual. 3. The inverter device should be firmly grounded to suppress radio frequency disturbance and avoid electric shock caused by leakage of the inverter. 4、 ...

The servo system is mainly composed of a servo controller, a drive circuit, a servo motor and the corresponding reaction testing equipment. (1) Servo motor Servo motor refers to the motor that controls the mechanical components in the servo system, and the servo motor has an encoder inside, which can respond to the movement in real time.

1. The main reason for VFD overload (1) Mechanical overload. The main characteristic of overload is the heating of the motor, which can be detected by reading the operating current on the display. (2) The three-phase voltage imbalance leads to excessive running current in a certain phase, resulting in overload tripping. It is characterized by uneven heating of the motor ...

Those who know more about Delta's automation know that Delta's inverters have two main series: "M300" and "C2000". "Compact Inverter M300 Series": This series has been introduced many times before, including ...

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...

1. After the inverter is repaired, the power number needs to be corrected, don't forget it Generally, an inverter corresponds to a power number (also known as the number of horsepower), for example, a 75 kilowatt inverter is set under heavy load, and 100 kilowatts is set under light load. In this way, the customer will not use it to present ...
