"MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 18.5KW.
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 device is the first power of the AC power conversion to DC (DC), the process is called rectification FR-A820-90K-1 Programming Manual.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter) FR-A820-90K-1
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. "Convert connectors to e-CON FR-A820-90K-1 Programming Manual. Convert connector to screw relay terminal.
According to the location of the connection equipment distribution module. Power: 37kw.
Voltage: 200V.
There are 100% braking torque output in continuous regeneration, which can correspond to the continuous regeneration operation of the pipeline control.
There is no need to install the braking unit for each frequency converter, which can reduce the comprehensive space and reduce the comprehensive cost FR-A820-90K-1 Programming Manual.
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving. 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.
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 motor power used to select the DC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose FR-A820-90K-1 Manual . ) Enter 32 points or 32 points;
Divided into 16 points, 16 points out of the output.
Directly connected to the input and output terminals of PLC;
Can play a role in replacing the terminal row;
Can alsoo be far away from the PLC of the site when the input and output devices;
Use as relay;
In order to reduce the time of the input and output connection FR-A820-90K-1 Manual .
