FR-A700 converter products are suitable for all kinds of high load requirements of the equipment FR-A740-55K-CHT PDF.
Such as lifting, lift, printing and dyeing, printing and dyeing, material coiling and other general occasions.
High level driving performance.
Unique sensorless vector control mode,
A wide variety of mechanical equipment can be operated at high precision in the super low speed region without the need of the encoder FR-A740-55K-CHT
With torque control mode,
And in the speed control mode can use the torque limit function FR-A740-55K-CHT PDF.
With vector control function (with encoder),
Frequency converter can achieve position control and fast response, high precision speed control (zero speed control, servo lock, etc.) and torque control. Purpose: to operate, monitor, and change the parameters through the network.
Applicable frequency converter: FR-A700, FR-F700, FR-E700 FR-A740-55K-CHT PDF. Length: 1.5m.
Specification: FX round connector. "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 PLC FUNCTION PROGRAMMING 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 PLC FUNCTION PROGRAMMING MANUAL.
But there are many control circuit, and no torque is introduced, so the system performance has not been improved MITSUBISHI PLC FUNCTION PROGRAMMING 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-A740-55K-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 maiinly 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-A740-55K-CHT PLC FUNCTION PROGRAMMING 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-A740-55K-CHT Manual. "
