"MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 0.75KW.
The use of frequency converter motor is in order to speed, and reduce the starting current FX3G-14MT/DSS PDF.
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.
The direct current (DC) is transformed into alternating current (AC) and its scientific term is "inverter" (inverter) FX3G-14MT/DSS
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 FX3G-14MT/DSS PDF. "Output points: 8 points.
Output form: relay output.
Input signal voltage: DC24V.
FX2N series expansion unit
Expansion unit is an input and output expansion device with a built-in power supply.
As with the basic unit, the extension unit can be connected to a variety of input and output and special extension equipment FX3G-14MT/DSS PDF.
Can connect to FX3GA/FX3G, FX3GE and FX3U.
AC power model, the built-in maximum DC24V 250mA/460mA supply power.
Because all models of FX series are built in high speed counter,
So the high speed control can be realized by the simple procedure MITSUBISHI USER'S MANUAL.
The input of the basic unit is built in the anti jitter filter,
One part as digital filter,
Sensitivity adjustment unit can reacch 1ms FX3G-14MT/DSS Manual.
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 MITSUBISHI USER'S MANUAL.
Extended function expansion board and special adapter,
Data links and communication with external serial devices. MITSUBISHI inverter FR-D720S series.
Voltage level: single phase 200V.
Frequency converter capacity: 0 MITSUBISHI USER'S MANUAL. 2KW.
VVVF frequency control, vector control frequency conversion, direct torque control is a kind of AC - DC - AC frequency conversion.
The common drawback is that the input power factor is low, the harmonic current is big, and the DC circuit needs large energy storage capacity,
Renewable energy and can not be fed back to the power grid, which can not be carried out in the four quadrant operation. To this end, the matrix type of AC - AC variable frequency arises at the historic moment.
Because the matrix type alternating current frequency saves the intermediate DC link, thereby, the electrolytic capacitor with large volume and high price can bbe omitted FX3G-14MT/DSS USER'S MANUAL.
It can achieve a power factor of L, the input current is sinusoidal and can run in four quadrant, the power density of the system is large.
Although the technology is not yet mature, but still attract a large number of scholars in-depth study FX3G-14MT/DSS Manual.
In fact, the quality is not the indirect control current, flux, but the torque is directly used as the control to achieve.
