MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 18.5KW.
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%) FX3S-20MT/DS PDF FX3S-20MT/DS
Starting with power frequency power supply, the starting current is 6~7 times of the rated current, therefore, the impact on the mechanical and electrical.
The inverter drive can be smoothly start (start time longer).
The starting current is 1.2~1.5 times of the rated current, and the starting torque is 70%~120% rated torque;
For the inverter with the torque automatic enhancement function, the starting torque is more than 100%, which can start with full load FX3S-20MT/DS PDF. Series Name: small F930GOT.
System screen display language: chinese.
Display: 4.4 inches.
Display color: monochrome (blue / white).
Display device: LCD STN.
Resolution: 240 * 80.
Installation type: panel mounting FX3S-20MT/DS PDF.
The built-in communication port: RS-422 (1ch) /RS-232C (1ch).
Power supply voltage: DC24V.
Touch screen also known as user interface or user interface,
Is a communication interface between human and computer,
Is an important part of the computer system.
Is a medium for interaction and information exchange between the system and the user,
It realizes the transformation between the internal form of information and the acceptable form of human being.
Where there is a touch screen to participate in the field of human-computer information exchange. Power: 1.5kw.
Purpose: to suppress the power harmonics.
Improve the power factor, reduce the input side of the high harmonic current.
Make sure that this option is installed in the FR--A820-03800 (75K) and FR-A840-02160 (75K) and above capacity and above capacity FX3S-20MT/DS datasheet.
At the same time the installation options in the use of 75kW and above motor. (the IP55 series has a built-in DC reactor.)
According to the motorr power used to select the DC reactor FX3S-20MT/DS datasheet.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.)
