The braking ability provided by the braking capacity is larger than that provided by the external braking resistor.
Can also be connected without built-in brake transistor inverter.
Three types of discharge resistors are available.
Please select according to the required braking torque.
Power: 75kw.
Voltage: 400V.
The power factor of the input power factor is up to 0.99 and above (100% load).
Can be connected to multiple inverters, to achieve a common DC bus mode.
Equipped with standard power retrogradation function. Uses: for external BCD or binary digital signal to do the frequency of a given MITSUBISHI FR-BU2-H55K.
Applicable frequency converter: FR-A700, FR-F700, FR-E700"If can use: closed loop vector control; spindle positioning, position control, speed control, servo lock zero FR-BU2-H55K
Suitable frequency converter: FR-A700. MITSUBISHI inverter FR-F740 series.
Voltage level: three phase 400V.
Frequency converter capacity: 560KW.
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 MITSUBISHI FR-BU2-H55K.
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 MITSUBISHI FR-BU2-H55K.
Therefore, if the magnetic flux decreases, the electromagnetic torque will decrease, which leads to the reduction of the load carrying capacity FR-BU2-H55K MITSUBISHI. Power: 11kw.
Purpose: high frequency braking resistor.
The use rate of the built-in regenerative brake of the transducer can be promoted FR-BU2-H55K MITSUBISHI.
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 FR-BU2-H55K MITSUBISHI.
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-BU2-H55K.
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 MITSUBISHI FR-BU2-H55K.
The installation of thermal relay, to avoid overheating and burn the braking resistor.
