MITSUBISHI FR-A7ND datasheet PDF catalog FR-A7ND PDF datasheet

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. Does not remove the short circuit chip will lead to overheating of the brake resistor FR-A7ND datasheet PDF catalog FR-A7ND PDF datasheet.
The utilization rate of the regenerative braking should be less than the allowable brake use rate in the above table FR-A7ND
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. 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 FR-A7ND datasheet PDF catalog FR-A7ND PDF datasheet.
The installation of thermal relay, to avoid overheating and burn the braking resistor. MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 500KW.
The main circuit of the inverter can be divided into two categories in general: voltage type is the voltage source of the DC converter for AC inverter,
The filtering of the DC circuit is the capacitance; the current mode is the DC conversion of the current source to the AC inverter,
The DC loop filter is the inductor FR-A7ND datasheet PDF catalog FR-A7ND PDF datasheet.
Why is the frequency of the inverter voltage proportional to the change?
The electromagnetic torque of any motor is the result of the interaction between the current and the magnetic flux, the current is not allowed to exceed the rated value, otherwise it will cause the heating of the motor.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity. Total input and output points: 32 points.
