"MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 1.5KW.
The use of frequency converter motor is in order to speed, and reduce the starting current FX0N Series 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) FX0N Series
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, adjusttable voltage inverter, we called the inverter FX0N Series PDF FX0N Series Manual. "Power: 0.4kw.
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 FX0N Series PDF. Does not remove the short circuit chip will lead to overheating of the brake resistor.
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 MITSUBISHI PROGRAMMING MANUAL.
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.
The installation of thermal relay, to avoid overheating and burn the braking resistor MITSUBISHI PROGRAMMING MANUAL. Input signal: platinum temperature resistance 3 wire 4 points.
Sensor current: 1mA.
Applicable PLLC:FX1N, FX2N, FX3U, FX2NC (to FX2NC-CNV-IF) FX0N Series PROGRAMMING MANUAL.
