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 ...

The inverter used in industry is divided into two types: single-phase and three-phase, which is distinguished from the voltage supplied by the main circuit, which is the main circuit to be connected to RST three-phase 380 volt alternating current, and the output is connected to the UVW three-phase line to the motor; And the single-phase is the main circuit connected to the single-phase 220 volt LN alternating current, the output is the same ...

1. The transmitter does not return to zero under no pressure? Answer: The cleaning method is to remove the transmitter from the device position, investigate whether the zero position is normal, and replace the pipeline sealing ring if it is normal. Check together whether the transmitter is perpendicular to the piping assembly, and if not, adjust the transmitter zero. ...

1. Before the inverter is energized The temperature and humidity of the surrounding environment should be detected first. Too high a temperature will cause the inverter to overheat the alarm. When severe, it will directly lead to damage to the power supply device of the inverter and short circuit of the circuit; Excessive humidity of the air can lead to a direct short circuit inside the inverter. When the inverter is in operation ...

The main way to use the inverter is to change the output frequency to achieve the controllability of the motor speed, so do you know what steps are required to complete the output frequency controllability? One of the main points is how to complete the change of the frequency signal supplied by the inverter equipment.

This example is an example of the equipment used to connect a Modbubs to Profinet gateway to a Delta inverter, and the equipment used is a Siemens 1200 PLC, a Delta inverter, and a DJI Modbus to Profinet gateway. 1、Mo ...

1. No-load energizing test of inverter 1. Ground the grounding terminal of the inverter. 2. Connect the power input terminal of the inverter to the power supply through the leakage maintenance switch. 3. Check whether the factory display window of the inverter is normal, if it is incorrect, it should be reset, no ...

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 ...

Programming equipment: simple programmer, most only accept mnemonic programming, and some can also be programmed graphically (such as Japan's Toshiba EX programmable controller). The cluttered one has a graphical programmer, which can be programmed in the trapezoidal language. Some also have dedicated computers that can be used for other ...

Inverter is a modern factory in the use of a very ubiquitous equipment, this is a new type of equipment, the price is very noble, and the price of inverter repair is also very expensive, so in the process of using inverter, pay attention to the use of inverter, on the one hand, inverter, delay inverter ...

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 necessity of braking resistance If the regenerative energy that occurs during deceleration and descent in the application is too large, there is a possibility that the voltage of the main circuit inside the inverter will rise, causing damage. Due to the built-in overvoltage maintenance function in the inverter, the overvoltage of the main circuit (O ...

Daily View Item 1: Check whether the sound of the motor changes abnormally during operation, including whether there is vibration during the operation of the motor. Project 2: Check if the environment of the inverter unit has changed. For example, whether the ambient temperature is normal. Familiar with Delta's inverter ...

High power means increased cost The use of high-power fan inverter can indeed meet the various production needs of enterprises, but high-power also means an increase in production costs. Because the more power, the more power will be consumed. Assuming that a 20KW fan inverter can ...

1. The necessity of braking resistance If the regenerative energy that occurs during deceleration and descent in the application is too large, there is a possibility that the voltage of the main circuit inside the inverter will rise, causing damage. Because usually the inverter has a built-in overvoltage maintenance function, the main circuit overvoltage (O...
