Precautions for storage of Delta inverter VFD-VE

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, ...

Far EasTone Telecommunications, Delta Electronics, and Microsoft Corporation in Taiwan, China, announced today 8 that the three parties will work together to build a 5G smart workshop. With the characteristics of "big things" (network big data, artificial intelligence technology, Internet of Things technology), combined with 5G80MHz continuous network bandwidth, the integration of servo independent innovation and intelligence ...

I. Introduction Some devices will have many transmission organizations, and it is impossible for the transmission organization to achieve 100% speed synchronization, so it is necessary to introduce ------ The final motor speed of the pendulum roller is *** := main speed + (+-auxiliary correction change) Use the site ...

Excellent open-loop speed control without slip compensation There is high torque at low degree, so there is no need to supply too much torque to enhance c. Lower loss, higher power Higher power echoes – especially for stepped loads Big...

Delta's programmable controllers, also known as Delta programmables, delta programmable controllers, delta programmable controllers, etc., are electronic devices specially designed by Delta for the industrial automation category to complete digital operations. Delta's PLC uses programmable memory to store execution logic inside it.

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

In addition to adhering to the high reliability, excellent efficiency and outstanding power of Delta's UPS products, the N1-3kVA series has three obvious core advantages: 1. High availability planning Delta N 1-3kVA series ...

(1) About the synchronous switching function. Now, in addition to the off-line UPS power supply with an additional output power of less than 500VA, the off-line UPS power supply with square wave output is still selected for conversion control without mains synchronization function, and all UPS power supplies with an output power of 1KVA and above are performing the conversion operation of mains power supply to inverter power supply.

Delta inverter is a device that converts the power supply (50Hz or 60Hz) into AC power supply of various frequencies to realize the variable speed operation of the motor.

1. The influence of leakage current on the motor and countermeasures If the wiring length is very long, the stray capacitance between the wires will increase, resulting in leakage current. It will initiate overcurrent maintenance, increase leakage current or not ensure the correctness of the current display. The bad situation is that the inverter will ...

1. Record the operation data and shortcomings of the Delta: The operation data of the Delta inverter and the motor should be recorded every day, including the output frequency, output current, output voltage, DC voltage inside the inverter, radiator temperature and other parameters, and compare them with reasonable data, so as to facilitate early detection of defects.

(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...

1. Vibration circuit: the leakage-source and R4 of the main winding N1 and Q1 of the switching transformer are the channels of the power supply operation current; R1 provides the starting current; The self-powered windings N2, D1, and C1 constitute the power supply voltage of the vibrating chip. The normal operation of these three links is the prerequisite for the power supply to vibrate.

Rectifier circuits It consists of six rectifier diodes from VD1 to VD6 to form an uncontrollable full-wave rectifier bridge. Regarding the rated power supply of 380V, the reverse withstand voltage value of the diode should be 1200V, and the forward current of the diode is 1.414-2 times of the rated current of the motor. ...

1. Initialize parameters Before wiring, initialize the parameters. On the control card: select the control method; Reset the PID parameter to zero; When the control card is powered on, the enable signal is closed by acquiescence; Save this condition to make sure that the control card ...

When you are using the motor, if you simply change the frequency, your motor will most likely be burned out. This problem is especially acute when the frequency is reduced. In order to prevent the motor from burning out, the inverter must change the voltage at the same time as the frequency. ...

There are many models of Delta's power supplies, and the currents and functions supported are also different, so how to choose? 　　VX Series Power Supplies. VX270: Active PFC270w, but 12v is still small and can only be used at low power. Active PFC and 12v output up to 276w at 300...

As far as I know, since the advent of active induction motors, there has been a variable frequency operation in the way of communicating generators. Change the rotational speed of the generator, and change its output frequency. Before the advent of high-speed transistors, this was one of the main ways to change the speed of the motor, but due to the decrease in the speed of the generator ...

Product series: CP/CH/CT/C2000/C200/MS300/MH300/VE/ED/VJ Fault Codes: noCL Fault clarification: The lack of oil is correct Solution: 1. Check the fuel level of the fuel tank 2. Check whether there is any leakage on the oil road.

1. Soft start is energy-saving The hard start of the motor will cause a serious impact on the power grid, and it will also require too high the capacity of the power grid, and the large current generated when the motor is started and the sensation will cause great damage to the baffle and valve, and the service life of the equipment and pipeline will be extremely unlucky. And the use of inverter energy-saving devices ...
