Power: 7.5kw.
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-F720-45K 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 FR-F720-45K
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 FR-F720-45K PDF. 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. 20 pin connector on both ends of the circular multi-core cable FR-F720-45K PDF.

FR-A800 series equipped with the latest high-speed processor MITSUBISHI TECHNICAL MANUAL. Has better control performance and response speed,
Products to ensure stable and accurate operation in a wide variety of applications.
Enhanced real-time sensorless vector control and vector control functions, can meet the needs of various kinds of machinery and equipment MITSUBISHI TECHNICAL MANUAL.
For paper, textile, wire, a variety of tape and other products of the extension of the machine processing, linear speed control is essential.
It can respond quickly to the change of production line speed and avoid the phenomenon of uneven winding.
This helps to achieve a stable supply of high quality products MITSUBISHI TECHNICAL MANUAL. "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 FR-F720-45K TECHNICAL MANUAL.
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 fixeed frequency and a certain voltage of the inverter FR-F720-45K Manual .
For the inverter as the frequency adjustable, adjustable voltage inverter, we called the inverter. "
