Analog input: 2.
Analog output points: 1 points.
Weight: 0.1kg.
FX3 series can be connected to the 2 channel input (voltage: DC0~10V, or current DC4~20mA), as well as 1 channel output (DC0~10V, or current: DC4~20mA) of the adapter FX3U-4AD PDF.
Each channel can be specified as a current input or voltage input.
Connecting FX3SA, FX3S, FX3GA, FX3G, and FX3U main body, the need to convert the adapter or function expansion board FX3U-4AD MITSUBISHI inverter FR-E720 series.
Voltage level: 3 phase 200V.
Frequency converter capacity: 11KW.
In order to ensure the reliability of production, all production machinery in the design of power with drive, there is a certain amount of surplus FX3U-4AD PDF.
When the motor can not run under full load, in addition to meet the requirements of power driven,
The surplus torque increases the active power consumption, resulting in the waste of electric energy.
Speed control method of fan and pump equipment traditional by regulating the entrance or exit of the baffle, valve opening to regulate air flow and water flow
, the input power is large, and a large amount of energy consumption in the baffle, the valve in the process of closure FX3U-4AD PDF.
When using variable frequency control, if the flow rate is reduced, the speed of the pump or fan can be reduced to meet the requirements MITSUBISHI INSTALLATION MANUAL. Convert connector to screw relay terminal.
2 wire connection, no need to use common terminal.
Positive common end use. "MITSUBISHI inverter FR-F720P series.
Voltage level: three phase 200V.
Frequency converter capacity: 2 MITSUBISHI INSTALLATION MANUAL. 2KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%) MITSUBISHI INSTALLATION MANUAL.
It is based on the overall effect of three-phase waveform generation,
In order to approach the ideal circular rotating magnetic field in the air gap of the motor,
A generation phase modulation waveform control inscribesthe polygon to approach the circle way.
After practice, it has been improved, that is, the introduction of frequency compensation, can eliminate the error of speed control;
By feedback estimation of flux amplitude, eliminating the influence of stator resistance at low speed, the output voltage and current closed loop,
In order to improve the accuracy and stability of the dynamic.
But there are many control circuit, and no torque is introduced, so the system performance has not been improved.
Frequency converter is aa power control device which uses the power of the power semiconductor device to change the power frequency to another frequency,
Can realize the asynchronous motor soft start, variable frequency speed regulation, improve the operation precision, change the power factor, over current / over voltage / overload protection and other functions FX3U-4AD Manual.
The use of frequency converter motor is in order to speed, and reduce the starting current.
In order to produce a variable voltage and frequency,
The equipment to the power of the AC power conversion to DC (DC), the process is called rectification.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter).
General inverter is the DC power supply inverter for a certain fixed frequency and a certain voltage of the inverter.
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter.
Inverter output waveform is simulated sine wave,
Is mainly used in three-phase asynchronous motor speed control, and also called frequency governor.
For the variable frequency inverter, whichh is mainly used in the testing equipment of instrument and meter,
To sort out the waveform, you can output the standard sine wave, called the inverter power supply FX3U-4AD INSTALLATION MANUAL.
The general inverter is 1520 times inverter price.
The main device called "inverter" because of the voltage or frequency of the inverter device ",
Therefore, the product itself is named "inverter", that is: inverter FX3U-4AD Manual. "
