Frequency converter can achieve position control and fast response, high precision speed control (zero speed control, servo lock, etc FR-A846-00038-2-60 datasheet PDF catalog FR-A846-00038-2-60 PDF datasheet. ) and torque control. Master station module for CC-Link/LT.
I/O control can be used in the province of CC-LINK/LT.
Is to make PLC CC-LINK/LT as the main station of the FX system module.
The master station module and the remote I/O module can be connected by a special connector, and achieve the purpose of the distribution of the province FR-A846-00038-2-60 datasheet PDF catalog FR-A846-00038-2-60 PDF datasheet.
Up to 64 remote I/O station modules can be connected.
Remote I/O module is assigned a common X, Y soft components,
By using the same procedure as the common input and output.
Even if the use of 2 points, 4 points of the remote I/O module, the number of soft components can be continuously assigned,
So it can be efficiently allocated I/O. Total points: 32 points.
Input points: 16 points.

Output points: 16 points.
Output form: Transistor (drain type).
Connection status: connector.
In order to extend the input output of the device.
Also has a built-in power supply products.
The maximum number of points for the input and output is 256.
Expansion module: up to 16 units (in addition to the power expansion module)
The total number of CC-Link, AnyWireASLINK, and Bitty series of remote I/O is 512 points. "MITSUBISHI inverter FR-F720P series.
Voltage level: three phase 200V.
Frequency converter capacity: 22KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%).
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 andd meter,
To sort out the waveform, you can output the standard sine wave, called the inverter power supply FR-A846-00038-2-60 datasheet PDF catalog FR-A846-00038-2-60 PDF 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 FR-A846-00038-2-60 datasheet PDF catalog FR-A846-00038-2-60 PDF datasheet. "
