Output points: transistor output 4 points, 4 point CT input.
Weight: 0.4KG.
Temperature sensor with 4CH input control output,
Double position control, standard PID control,
Heating and cooling PID control, cascade control FX3G-14MR/DS PDF.
By using the combination of the analog output module,
PID control of voltage or current can be realized FX3G-14MR/DS
New with cascade control. Through the master / slave station of the 2 controllers,
According to the temperature change caused by external disturbance, the temperature can be adjusted quickly.
Can connect FX3GA/FX3G, FX3GE, FX3U series FX3G-14MR/DS PDF.
When connecting to FX3UC or FX3GC, you need FX2NC-CNV-IF or FX3UC-IPS-5V. "MITSUBISHI inverter FR-F720P series.
Voltage level: three phase 200V.
Frequency converter capacity: 3.7KW.
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%) FX3G-14MR/DS PDF.
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 MITSUBISHI PROGRAMMING MANUAL.
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 MITSUBISHI PROGRAMMING MANUAL.
But there are many control circuit, and no torque is introduced, so the system performance has not been improved MITSUBISHI PROGRAMMING MANUAL.
Frequency converter is aa 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 FX3G-14MR/DS Manual.
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 FX3G-14MR/DS PROGRAMMING MANUAL.
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 FX3G-14MR/DS Manual. "
