Robot contactors are noisy? Cause: It is likely that the joint contact surface of the contactor is uneven, and the surface is sand or rust. The result will constitute a phase loss, which will lead to the burnout of contactors, switch frequency conversion and other components. Solution: will control the ...

Investigation of the function of the inverter system Before debugging the inverter, it is necessary to carefully read the instruction manual and related information of the inverter to be debugged to understand the use environment and precautions. Especially before the inverter is energized, it is necessary to carefully investigate and check whether the inverter has obvious problems.

The external terminals of the inverter, RH, RM, RL, are speed control terminals. Through the combination of these terminals, three-speed and seven-speed control can be completed. In addition, the other terminals can be redefined, and the fifteen-speed speed can be controlled. ...

In order to thoroughly implement the spirit of General Secretary Xi Jinping's important instructions that the economic power must be a maritime power, a shipping power, economic development, a strong country, and transportation, especially shipping, and the implementation of the outline for the construction of a transportation power, the port ship shore power system has become the standard for green ports.

It is important to set the torque to improve the function. When the power frequency of the motor decreases, the speed of the motor will also decrease, and if the load torque remains unchanged, the output power will also decrease. According to the principle of conservation of energy, if the rotation of the load ...

1. The capacitance is generally indicated by "C" plus a number in the circuit (e.g., C25 indicates the capacitance numbered 25). A capacitor is a component consisting of two metal films close to each other and separated by an insulating material in the center. The characteristic of the capacitor is mainly to communicate through the DC block. The size of the capacitance is ...

First of all, we need to understand a truth, that is, many times the good and bad of things are relative. The variable frequency drive (VFD) is used as a power source to drive the operation of the motor, and its fundamental role is to regulate the speed. If the wiring is normal, the parameters are reasonable, and the load is not ...

The gantry milling machine is a machining equipment for processing larger workpieces, and its electrical control system includes two parts: the main transmission of the workbench and the logical control of the feed organization. Henan Jiaozuo Maike Company has a gantry milling machine, which has been used for many years since the 70s. The main drive of the operating table of the gantry milling machine is selected ...

1. Whether it has perfect maintenance function There will be many problems in the production process of the equipment, and if you want to prevent accidents, the equipment must have a perfect maintenance function, so as to prevent the loss of the enterprise. Therefore, when buying an exhaust fan inverter, you need to understand the safety function of the equipment first.

1. Step-by-step decreasing method The so-called gradual reduction method is to gradually reduce the scale of the problem through the analysis of the problem phenomenon and the identification of measurement parameters, and finally implement it to the specific circuit or component that causes the problem. In essence, it is a certainty, a negation, a negation, a negation, a final ...

1. Obtain accurate motor parameters from low to high parameters at different frequencies, and establish motor models of corresponding frequency bands in different frequency segments, so that the inverter can control the motor from low to high. 2. V/F control (1) It is possible to select 15 pre-set V/...

It is necessary to separate the signal line from the power line: when using analog signals for long-distance control of the inverter, in order to reduce the disturbance of the analog amount from the inverter and other equipment, please separate the signal line of the control inverter from the strong current circuit (main circuit and sequential control circuit). Inverter ...

Planning specifications: The planning of inverter cabinets should conform to relevant national norms and industry norms, such as GB/T15576-2018 "Low-voltage Distribution Cabinet", GB7251.1-2017 "Low-voltage Complete Switchgear and Control Equipment", etc. Material specifications: The materials of the control cabinet should conform to the relevant codes and regulations.

What is a frequency converter? Variable Frequency Drive (VFD) uses inverter technology and microelectronics to change the operating power frequency of the motor to control the power control unit of the communication motor. The inverter is mainly composed of rectifier (from communication to DC), inverter, inverter (from DC to communication) ...

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

1. Do a good job of moisture-proof operations, clean up water and oil stains on site, insist on the boring environment of electrical equipment, and pay attention to preventing the inverter from being exposed. 2. Do a good job of maintenance and maintenance, take advantage of the shutdown for maintenance, clean the frequency conversion dust, and clean the frequency conversion air duct; Tighten the frequency conversion cable joint to prevent loosening, ...

The motor is able to rotate, but the operating current exceeds the rated value, which is called an overload. The fundamental reflection of overload is that although the current exceeds the rated value, the fluctuation of the excess is not large, and it generally does not constitute a large inrush current. 1. The main reason for overload (1) Excessive mechanical load ...
