Brand:
MITSUBISHI
Name: 3 phase 200V converter
Model: FR-F720P-15K
"MITSUBISHI inverter FR-F720P series.
Voltage level: three phase 200V.
Frequency converter capacity: 15KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%).
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. "
Superior high efficiency IPM motor.

IPM motor MM-EFS series can not be used to run the power frequency power.
The total wiring length of the IPM motor shall not exceed 100m.
1 inverters can not connect multiple IPM motors at the same time MITSUBISHI FR-F720P-15K. Applicable motor capacity: 0.4KW.
Rated current: 1.2A.
Power supply voltage: three phase 400V FR-F720P-15K
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.
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 MITSUBISHI FR-F720P-15K.
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-F720P-15K. Power: 15kw.
Purpose: high frequency braking resistor.
The use rate of the built-in regenerative brake of the transducer can be promoted.
When using the FR-ABR type brake resistor, the short circuit piece between the terminal PR-PX is removed FR-F720P-15K MITSUBISHI. Does not remove the short circuit chip will lead to overheating of the brake resistor.
The utilization rate of the regenerative braking should be less than the allowable brake use rate in the above table FR-F720P-15K MITSUBISHI.
With the operating frequency of the brake resistor to reach 300 degrees C or higgher, it is necessary to take protective measures and cooling FR-F720P-15K.
MYS type resistor can be used. But please pay attention to the allowable brake use rate FR-F720P-15K MITSUBISHI.
Do not remove the terminal P/+ and P1 between thhe short circuit chip, in addition to connecting the DC reactor MITSUBISHI FR-F720P-15K.
The installation of thermal relay, to avoid overheating and burn the braking resistor.
