2 times the power consumption of the wind turbine and pump and the speed of the 3 power consumption is proportional to the speed of the rotating speed FX2N-80MT-ESS/UL PDF.
Through the speed control of the frequency converter to adjust the air flow, can reduce the power consumption FX2N-80MT-ESS/UL
Give full play to the performance of the motor.
The excitation current is always adjusted to the best state, which can improve the efficiency of the motor.
Load torque is smaller, can further improve energy efficiency.
For example, when a general motor is used, the optimal excitation control mode in the 4% motor load torque is about 30% more than that of the V/F control FX2N-80MT-ESS/UL PDF. Input / output form: relay output.
Output points: 8 points.
Input and 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 FX2N-80MT-ESS/UL PDF.
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 of 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.
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.
The number of connection points depends on the basic unit and the expansion unit. "MITSUBISHI inverter FR-F740P series.
Voltage level: three phase 400V.
Frequency converter capacity: 110KW.
It is based on the overall effect of three-phase waveform generation,
In order to approach the ideal circular rotating magnetic field in the air gap of the motor,
A generation phase modulation waveform control inscribesthe polygon to approach the circle way.
After practice, it has been improved, that is, the introduction of frequency compensation, can eliminate the error of speed control;
By feedback estimation of flux amplitude, eliminating the influence of stator resistance at low speed, the output voltage and current closed loop,
In order to improve the accuracy and stability of the dynamic.
But there are many control circuit, and no torque is introduced, so the system performance has not been improved.
Frequency converter is a power control device which uses the power of the power semiconductor device to change the power frequency to another frequency,
Can realize the asynchronous motor soft start, variable frequency speed regulation, improve the operation precision, change the power factor, over current / over voltage / overload protection and other functions.
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 equipment to the 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).
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.
Inverter output waveform is simulated sine wave,
Is mainly used in three-phase asynchronous motor speed control, and also called frequency governor.
For the variable frequency inverter, which is mainly used in the testing equipment of instrument and meter,
To sort out the waveform, you can output the standard sine wave, called the inverter power supply FX2N-80MT-ESS/UL datasheet.
The general inverter is 1520 times inverter price.
The main device called "inverter" because of the voltage or frequency of the inverter device ",
Therefore, the product itself is named "inverter", that is: inverter FX2N-80MT-ESS/UL datasheet. "
