Power: 11kw.
Purpose: high frequency braking resistor.
The use rate of the built-in regenerative brake of the transducer can be promoted.
When using the FR-ABR type brake resistor, the short circuit piece between the terminal PR-PX is removed. Does not remove the short circuit chip will lead to overheating of the brake resistor FX3G-40MT/DSS Positioning Control Edition Manual FX3G-40MT/DSS USER'S MANUAL FX3G-40MT/DSS
The utilization rate of the regenerative braking should be less than the allowable brake use rate in the above table.
With the operating frequency of the brake resistor to reach 300 degrees C or higher, it is necessary to take protective measures and cooling.
MYS type resistor can be used. But please pay attention to the allowable brake use rate.
Do not remove the terminal P/+ and P1 between the short circuit chip, in addition to connecting the DC reactor FX3G-40MT/DSS Positioning Control Edition Manual FX3G-40MT/DSS USER'S MANUAL.
The installation of thermal relay, to avoid overheating and burn the braking resistor. For the operation panel (FR-DU08) between the connector and the connecting cable."MITSUBISHI inverter FR-F720P series.
Voltage level: three phase 200V.
Frequency converter capacity: 30KW.
When the ring is opened, the frequency converter is provided with a load of the motor when the motor is operated with a load at a given frequency,
The range of the motor speed in the rated slip ratio (1%~5%) changes FX3G-40MT/DSS Positioning Control Edition Manual FX3G-40MT/DSS USER'S MANUAL.
For the requirements of relatively high precision, even if the load changes are also required to operate at a given speed of the occasion,
Inverter with PG feedback function can be used (selection).
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 meeter,
To sort out the waveform, you can output the standard sine wave, called the inverter power supply FX3G-40MT/DSS Positioning Control Edition Manual FX3G-40MT/DSS USER'S 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-40MT/DSS Positioning Control Edition Manual FX3G-40MT/DSS USER'S MANUAL. "
