Applicable motor capacity: 2.2KW.
Rated current: 1.2A.
Power supply voltage: three phase 400V.
Frequency converter and GOT supporting the use, to achieve a higher price.
SIMPLE GOT series can be directly connected to the IS70 series inverter.
GOT can be directly connected with the inverter. After connecting the two, the communication parameters can be automatically set MITSUBISHI FR-A7NL.
In addition, the software can display the soft component of the control function in the GOT, even when the multi frequency converter is connected,
Can also be unified management with 1 GOT FR-A7NL
Through the GOT screen to create software to import the picture data after the GOT,
Only use RS-422 connection GOT and frequency converter,
Can change the inverter speed / direction, monitoring the output frequency / output current and set a variety of parameters MITSUBISHI FR-A7NL. "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 FR-A7NL.
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 Directional control /PLG module MITSUBISHI Directional control /PLG module.
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 MITSUBISHI Directional control /PLG module.
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 iss 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 FR-A7NL.
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 MITSUBISHI FR-A7NL. "
