Anonymous users2024-02-15Many inverters are used in the same way! Introduce several common and simple methods of controlling frequency converters.
One. Wiring method of the main circuit of the inverter:
r s t three terminal blocks.
It is the power inlet end of the inverter, and three live wires are connected.
U v w is the motor that needs to be controlled for outlet termination.
Two. Types of control methods:
1.Panel controls. This control method is to start and stop the inverter through the inverter panel, modify the frequency, etc.
2.It can be controlled by an external controller or instrument. This control mode is mainly through the controller such as PLC to the inverter start and stop signal and frequency signal, this control mode can be divided into two kinds according to the different signal types. One type is switching signals and analog signals.
The other is communication digital signals.
Three. Control loop wiring.
Wiring of panel control: The panel control is the simplest and the least wiring, the enabling terminal of the inverter must be wired, no matter what control mode must be enabled inverter first! Potentiometer.
Wiring, if you feel that the panel button is not very convenient, then you can use the potentiometer to adjust the frequency, some of the inverter panel has been installed with the potentiometer, some are not installed, but the reserved potentiometer terminal!
Wiring via external controller or instrumentation: This type of wiring varies depending on the type of signal. 1.
The wiring method that relies on switching and analog control needs to be connected to the enabling terminal, the starting terminal, and the frequency given terminal is generally a current or voltage signal, and if it is a closed-loop control of PLD regulation, it is also necessary to connect the external sensor signal to the signal acquisition terminal of the inverter. 2.Relying on the communication mode to control the wiring mode of the inverter requires the enabling terminal, and the communication cable can be connected to the communication port of the inverter and the communication partner.
Four. Inverter parameter settings.
1.Panel control parameters: motor power; Control mode: panel; Frequency Given: Panel Potentiometer; upper and lower limits of frequency; There are slight differences in the parameters of different frequency converters!
2.Switching and analog control parameters: motor power; Control mode:
Remote; Frequency given: external analogue; External analog channel: depending on the wiring, choose which way to connect; External Analog Channel Signal Type:
According to the analog signal type of PLC output, there are generally current and voltage signals, and the signal range is determined according to the actual PLC analog output channel, commonly used 4 to 20mA, 0 to 10V; The PLC side needs to write the control program.
It can also be said to be the station number; Communication protocols.
Use communication protocols that are supported by both inverter and PLC; The PLC side needs to write a communication program!
Hope it helps!

The construction organization design should first calculate the engineering quantity, consider the construction plan, select the construction machinery and tools, and determine the approximate number of people according to the engineering quantity. Then draw the construction schedule and adjust it continuously until the conditions of reasonable construction period and minimum cost are met. Finally, after the failure of the preparation is determined, the calculation of the material use plan, the personnel and staff species entry plan, and the safety tremor measures are broken.
