MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 280KW.
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 FX2N-1RM-E-SET PDF catalog.
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit FX2N-1RM-E-SET
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 FX2N-1RM-E-SET PDF catalog. Function: AnyWireASLINK master station.
DC5V internal consumption current: 130mA. Connecting cable for handheld GOT and PLC.
Cable length: 10 meters.
Application: RS-422 connection and RS-232C connection. MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 110KW FX2N-1RM-E-SET PDF catalog.
When the ring is opened, the frequency converter is provided with a load of the motor when the motor is operated with a load at a given frequency,
The range of the motor speed in the rated slip ratio (1%~5%) changes MITSUBISHI Modular PDF catalog.
For the requirements of relatively high precision, even if the load changes are also required to operate at a given speed of the occasion,
Inverter with PG feedback function can be used (selection) MITSUBISHI Modular PDF catalog.
If the given acceleration time is too short, the output frequency of the inverter is far more than the change of the speed (electric angular frequency),
Converter will be due to flow over the current trip, the operation stopped, which is called stall MITSUBISHI Modular PDF catalog. "Power: 15kw.
Voltage: 400V.
Brake resistor, a kind of ripple resistance, is mainly used in the mechanical system of the inverter to control the speed of the motor,
Help the motor to be converted into heat energy due to the regenerative power of the motor.
Brraking unit principle: the brake unit is composed of a high power transistor GTR and its driving circuit FX2N-1RM-E-SET PDF datasheet.
Its function is to link the discharge current braking resistor capacitor voltage or not in the range of the time connsumed and the DC part "overpressure",
Need to add external braking components, in order to speed up the speed of the consumption of renewable energy FX2N-1RM-E-SET PDF catalog. "
