FX Series in the compact body built in superior performance, and strive to operate simple FR-A740-2.2K-CHT INSTRUCTION MANUAL.
In addition, rich options can meet the various needs of customers FR-A740-2.2K-CHT
In the virtual factory will be rich in the function of a part of the introduction.
It is easy to control the analog quantity of the application.
Can be extended to all models in the FX series analog devices.
Function extension board, special adapter without programming can be used for communication.
FX2N extension module FR-A740-2.2K-CHT INSTRUCTION MANUAL.
The expansion module is an input and output expansion device of the power supply from the basic unit or the expansion unit,
Can choose the relay or crystal output models, to 8 points for the unit to connect.
Can be extended to FX3GA/FX3G, FX3GE, FX3GC, as well as FX3U, FX3UC series,
When connecting to FX3UC or FX3GC, you need FX2NC-CNV-IF or FX3UC-1PS-5V.
The number of connection points depends on the basic unit and the expansion unit FR-A740-2.2K-CHT INSTRUCTION MANUAL. "MITSUBISHI inverter FR-F720P series.
Voltage level: three phase 200V.
Frequency converter capacity: 37KW.
When the ring is opened, the frequency converter is provided with a load of the motor when the motor is operated with a load at a given frequency,
The range of the motor speed in the rated slip ratio (1%~5%) changes MITSUBISHI FR-A740-2 MITSUBISHI FR-A740-2.2K-CHT Manual. 2K-CHT Manual.
For the requirements of relatively high precision, even if the load changes are also required to operate at a given speed of the occasion,
Inverter with PG feedback function can be used (selection).
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 MITSUBISHI FR-A740-2.2K-CHT Manual.
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 a 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.
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, which is mainly used in tthe testing equipment of instrument and meter,
To sort out the waveform, you can output the standard sine wave, called the inverter power supply FR-A740-2.2K-CHT BASIC.
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 FR-A740-2.2K-CHT INSTRUCTION MANUAL. "
