FR-F740P-75K-CHT In order to improve the accuracy and stability of the dynamic MITSUBISHI FR-F740P-75K-CHT

Brand: MITSUBISHI
Name: 3 phase 400V converter
Model: FR-F740P-75K-CHT
"MITSUBISHI inverter FR-F740P series.
Voltage level: three phase 400V.
Frequency converter capacity: 75KW.
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 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 the testing equipment of instrument and meter,
To sort out the waveform, you can output the standard sine wave, called the inverter power supply.
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 inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 18.5KW.
FR-A700 converter products are suitable for all kinds of high load requirements of the equipment.
Such as lifting, lift, printing and dyeing, printing and dyeing, material coiling and other general occasions MITSUBISHI FR-F740P-75K-CHT.
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-F740P-75K-CHT
With torque control mode,
And in the speed control mode can use the torque limit function.
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 MITSUBISHI FR-F740P-75K-CHT. ) and torque control. MITSUBISHI inverter series: FR-F820.
Voltage level: three phase 200V.
Power: 90kw.
SLD converter rated current: 475A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
PID target value can be set directly from the operator panel. Flexible change settings.
In the 1 inverter, through the PID control of parallel connection pump (up to 4 units) can adjust the amount of water and so on MITSUBISHI FR-F740P-75K-CHT.
1 pumps driven by parallel connection of the pump machine, in addition to the pump for power frequency drive.
The number of power frequency driven pump, according to the automatic adjustment of water MITSUBISHI Three phase 400V level inverter.
The liquid crystal panel options (FR-LU08) can be converted to a more intuitive display unit% units MITSUBISHI Three phase 400V level inverter.
Through the use of wind, temperature and other familiar units can be simple to maintain and adjust the display. Power: 22kw.
Voltage: 200V.
The surge voltage of the motor can be suppressed when the 400V motor is driven by a frequency converter.
Motor suitable for 5 MITSUBISHI Three phase 400V level inverter. 5 to 37kW. Power: 37kw.
Purpose: to suppress the power harmonics.
Connected to the inverter input, can be used to improve the power factor, reduce the input side of the high harmonic current.
According to the motor power used to select AC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.) MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 280kw.
SLD converter rated current: 610A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
The motor efficiency is not changed in the previous optimal excitation control,
At the same time, the newly developed advanced optimal excitation control can obtain larger torque at startup.
No need to adjust the parameters (plus deceleration time or torque, etc.), in a short time to speed up to a certain speed,
Can be carried out to maximize the efficiency of energy-saving drive motor.
The automatic tuning function of the loop constant of the motor is not consistent with the constant of the motor, the motor of other manufacturers, and the length of wiring is too long,
Optimum operating characteristic drive motorr FR-F740P-75K-CHT.
In the state of the sensor can not only drive the high efficiency and energy saving motor and PM motor (MM-EFS), but also can drive other companies induction motor and PM motor (permanent magnet synchronous motor).
Othher manufacturers of induction motors, can also be automatically tuned to achieve the best excitation control, thus expanding the use of energy saving MITSUBISHI FR-F740P-75K-CHT.
