Power: 2.2kw.
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-E720S-0.4K 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-E720S-0.4K
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-E720S-0.4K PPDF FR-E720S-0.4K Manual . 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. Power: 22kw.
Voltage: 400V FR-E720S-0.4K PDF.
There are 100% braking torque output in continuous regeneration, which can correspond to the continuous regeneration operation of the pipeline control.
There is no need to install the braking unit for each frequency converter, which can reduce the comprehensive space and reduce the comprehensive cost MITSUBISHI Instruction manual.
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving. Power: 3.7kw.
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 MITSUBISHI Instruction manual.
At the same time the installation options in the use of 75kW and aboove motor FR-E720S-0.4K Instruction manual. (the IP55 series has a built-in DC reactor.)
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 MITSUBISHI Instruction manual FR-E720S-0.4K Manual . ) Convert connector to screw relay terminal.
According to the location of the connection equipment distribution module.
