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 ...

1. The touch screen is controlled by PLC inverter 1. Now the general control of the inverter needs to use PLC to communicate with the inverter, read the information of the inverter, and then the touch screen communicates with the PLC in order to complete the control of the inverter to start, stop, and monitor the operation of the inverter.

There are three speed regulation methods for DC motors: armature loop string resistance, armature voltage regulation and speed regulation, and weak magnetic field speed regulation. The three speed regulation methods can achieve stepless speed regulation. 1. Armature loop string resistance The applied resistor is connected into the armature circuit to achieve the purpose of speed regulation. Speed Direction: Add ...

1. Acceleration and deceleration time The acceleration and deceleration time is usually confirmed by the rise and fall of the frequency setting signal. In the commissioning of Delta inverters, it is often used to set a long acceleration and deceleration time according to the load and experience value, and the frequency rise rate of the motor must be constrained when it accelerates to avoid overcurrent. When slowing down, ...

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 ...

Delta's touch screen consists of a contact detection component and a touch screen controller. The contact detection component is installed in front of the display screen to detect the user's contact orientation and is sent back to the touch screen controller; And Delta's touch screen controller's ...

1. Touch screen download program (1) Device software DOPSoft; (2) The communication line uses a square port data line; (3) device drive; (4) Configuration screen; (5) In the Stuff, select Download All Materials. 2. Communication settings (1) Touch screen settings ...

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 ...

How to wire the internal control and external control of Delta's inverter? Internal control: connect the main circuit power supply RST motor UVW, press the inverter panel to start and stop. Both the command source and the frequency frequency should be selected in the panel. External ...

1) Brief planning. Only one battery module, paired with several discrete components, is able to obtain a battery. 2) Shorten the development cycle. It is generally equipped with a variety of input, output, and battery module options. Users are also able to repeat or cross-stack, combined with modular batteries, to complete multi-channel ...

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 ...

All electronic equipment (including frequency converters) will generate some high-frequency or low-frequency noise during normal operation, and disturb the peripheral equipment through conduction or radiation. If the right EMC filter can be configured and the correct device method can be used, the disturbance can be reduced to a minimum. ...

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...

For those who are familiar with Delta's automation, they 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 MS300 (standard general-purpose type), MH300 (high power ...

(1) The harmonic current will directly cause the additional heating of the motor, so that the stator of the motor will exceed the rated temperature rise of the motor itself, so that the rated output capacity of the motor will be greatly reduced. ​ (2) The current wave output of the inverter ...

Project Background At present, electronic products such as mobile phones, computers, and IPads have become the standard in people's lives, which also promotes the rapid development of the electronic manufacturing industry. PCB (printed circuit board) is an important component in electronic products, with the trend of electronic products towards high-end, miniaturization ...

The rapid development of the national economy has opened up a broad shopping mall space for the growth of the civil aviation industry. In order to meet the surge in the number of flights, an international airport in Northwest China has invested in the third phase of the expansion project, and has been listed as the "number one project" for civil aviation development and the "benchmark demonstration project" for national civil aviation.

1. Check the operating status of the inverter, whether the voltage and current value during operation are within the normal range. 2. Carefully monitor and record the ambient temperature of the frequency conversion room, and the ambient temperature is generally between -10 °C and 40 °C. The temperature rise of the phase-shifting transformer should not exceed 130°C. 3. Avoid ...
