MITSUBISHI FR-E720-11K Applied Manual FR-E720-11K Instruction manual

"Power: 15kw.
Voltage: 400V.
Brake resistor, a kind of ripple resistance, is mainly used in the mechanical system of the inverter to control the speed of the motor,
Help the motor to be converted into heat energy due to the regenerative power of the motor.
Braking unit principle: the brake unit is composed of a high power transistor GTR and its driving circuit FR-E720-11K Applied Manual FR-E720-11K Instruction manual FR-E720-11K
Its function is to link the discharge current braking resistor capacitor voltage or not in the range of the time consumed and the DC part "overpressure",
Need to add external braking components, in order to speed up the speed of the consumption of renewable energy. "MITSUBISHI inverter series: FR-A800.

Mirror like ultra fine processing.
In order to adapt to the new material diversification, the machine adopts the most cutting-edge technology, more than ever more slim hard.
In order to be able to realize the fine cutting, grinding on the hard and hard material,
The need for high-speed operation has become more and more strong FR-E720-11K Applied Manual FR-E720-11K Instruction manual.
In order to cope with the increasing demand of logistics, every port in the world has a crane in every day.
A container filled with cargo.
We can achieve a new type of inverter products under the conditions of low speed and high torque to achieve smooth cargo handling operations,
Carry on the smooth movement to the heavy. 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.
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 iss necessary to take protective measures and cooling FR-E720-11K Applied Manual FR-E720-11K Instruction 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 thhe short circuit chip, in addition to connecting the DC reactor FR-E720-11K Applied Manual FR-E720-11K Instruction manual.
The installation of thermal relay, to avoid overheating and burn the braking resistor.
