MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 162KW.
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 FX3U-48MT/ES-A HARDWARE MANUAL.
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit FX3U-48MT/ES-A
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 FX3U-48MT/ES-A HARDWARE MANUAL. MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 75KW.
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 FX3U-48MT/ES-A HARDWARE MANUAL.
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).
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. Input and output form: DC input, relay output.
Input points: 4 points.
Output points: 8 points.
Because all models of FX series are built in high speed counter,
So the high speed control can be realized by the simple procedure.
The input of the basic unit is built in the anti jitter filter,
One part as digital filter,
Sensitivity adjustment unit can reach 1ms.
Using high speed counter automatically adjusted to the minimum value.
Through the high cost of the built-in positioning function and the expansion function to increase the number of control axis.
Extended function expansion board and special adapter,
Data links and communication with external serial devices.
FX2N extension module.
The expansion module is an input and output expansion device off the power supply from the basic unit or the expansion unit,
Can choose the relay or crystal output models, to 8 points for the unit to connect FX3U-48MT/ES-A Manual.
Can be extended to FX3GA/FX3G, FX3GE, FX3GC, as well as FX3U, FX3UC series,
When connecting to FX3UC or FX3GC, you need FX2NC-CNV-IF or FX3UC-1PS-5V FX3U-48MT/ES-A Manual.
The number of connection points depends on the basic unit and the expansion unit.
