FX2NC expansion module can be directly connected to the FX1NC, FX2NC, PLC FX3UC on the expansion of the input and output FR-E740-0.75K-CHT PDF.
Do not need to connect the cable and so on, therefore can carry on the compact expansion. Display: 7 segment digital display + icon display.
Can monitor, change the value of software components FR-E740-0.75K-CHT
Can also be simple to operate, change the value.
Equipped with a button operation can be used (operator certification function) and control through the PLC control function,
Can be used with the function expansion board FR-E740-0.75K-CHT PDF.
Can be installed directly to the FX3S, FX3SA, no wiring. Purpose: to operate, monitor, and change the parameters through the network.
Applicable frequency converter: FR-A700, FR-F700, FR-E700. Power: 37kw.
Voltage: 400V.
The surge voltage of the motor can be suppressed when the 400V motor is driven by a frequency converter FR-E740-0.75K-CHT PDF.
Motor suitable for 5.5 to 37kW. "MITSUBISHI inverter FR-F740P series.
Voltage level: three phase 400V.
Frequency converter capacity: 220KW.
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 Instruction 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 MITSUBISHI Instruction manual.
But there are many control circuit, and no torque is introduced, so the system performance has not been improved MITSUBISHI Instruction manual.
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 FR-E740-0.75K-CHT 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, which is mainlyy 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 FR-E740-0.75K-CHT Instruction 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 FR-E740-0.75K-CHT Manual . "
