MITSUBISHI FR-F740-0.75K-CHT Product information and technical parameters：
Brand: MITSUBISHI
Name: 3 phase 400V converter
Model: FR-F740-0.75K-CHT
"MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 0.75KW.
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 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).
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. "

Power: 11kw.
Purpose: to suppress the power harmonics.
Improve the power factor, reduce the input side of the high harmonic current.
Make sure that this option is installed in the FR-A820-03800 (75K) and FR-A840-02160 (75K) and above capacity and above capacity.
At the same time the installation options in the use of 75kW and above motor FR-F740-0.75K-CHT. (the IP55 series has a built-in DC reactor FR-F740-0.75K-CHT)
According to the motor power used to select the DC reactor.
(when the inverter capacity is greater than the motor capacity, is still based on the motor capacity to choose.) Power: 15kw.
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 FR-F740-0.75K-CHT. 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 FR-F740-0.75K-CHT.
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. Length: 30 meters.
Cable manufacturing specifications.
When there is no connection options, according to the table under the cable.
Using a parallel connection or a large size cable for connection between the terminal PG"" and "SD" and the motor end encoder FR-F740-0.75K-CHT. "Length: 3 meters.
Operation panel or parameter unit connection line. Power: 15kw.
Voltage: 400V.
The surge voltage of the motor can be suppressed when the 400V motor is driven by a frequency cconverter FR-F740-0.75K-CHT.
Motor suitable for 5.5 to 37kW. The operation, monitoring, parameter modification and other operations can be carried out by computer or PLC.
Purpose: to suppress the power harmonics.
