MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 185KW.
Frequency converter is the application of frequency conversion technology and micro electronics technology, by changing the motor operating power frequency mode to control the AC motor power control equipment MITSUBISHI QD63P6.
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit QD63P6
Inverter by the internal IGBT to adjust the output power supply voltage and frequency,
According to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition to the,
Inverter has a lot of protection functions, such as over current, over voltage, overload protection and so on MITSUBISHI QD63P6. Power: 2.2kw.
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 MITSUBISHI QD63P6. 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.
With the operating frequency of the brake resistor to reach 300 degrees C or higher, it is necessary to take protective measures and cooling.
MYS type resistor can be used. But please pay attention to the allowable brake use rate.
Do not remove the terminal P/+ and P1 between the short circuit chip, in addition to connecting the DC reactor.
The installation of thermal relay, to avoid overheating and burn the braking resistor. Input / output points: 4096 points.
Number of input and output elements: 8192.
Program capacity: 130 K step.
Processing speed: 0.0095 s.
Program memory capacity: 520 KB.
Support USB and RS232.
Support installed memory card.
Providing high speed communication between multiple CPU.
High speed and high precision data processing.
The processing speed of the real number (floating point) arithmetic has been greatly improved,
Addition instruction reached 0.014 mu s,
Therefore, it can support the request of high-speed, high-precision processing data processing.
In addition, the new addition of double pprecision ffloating point arithmetic instructions,
Simplify the programming, reduces the computational error when executing complex formula QD63P6.
Shorten the fixed scan interrupt time, high precision device.
The minimum interval of the fixed period interrruupt program is reduced to 100 s QD63P6.
The high speed signal can be accurately obtained, which makes the contribution to the higher precision of the device.
