FR-ABR-H7.5K | MITSUBISHI FR-ABR-H7.5K High frequency braking resistor

Brand: MITSUBISHI
Name: High frequency braking resistor
Model: FR-ABR-H7.5K
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.
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 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.
The installation of thermal relay, to avoid overheating and burn the braking resistor.

Power: 0.4kw.

The installation of thermal relay, to avoid overheating and burn the braking resistor. "Power: 55kw.
Voltage: 200V.
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 MITSUBISHI FR-ABR-H7.5K.
Braking unit principle: the brake unit is composed of a high power transistor GTR and its driving circuit.
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 FR-ABR-H7 FR-ABR-H7.5K MITSUBISHI. 5K MITSUBISHI. "Purpose: to operate, monitor, and change the parameters through the network.
Applicable frequency converter: FR-A700, FR-F700, FR-E700. MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 5.5KW.
Vector control variable frequency speed control is the practice of the asynchronous motor in the three-phase coordinate system of the stator current Ia, Ib, Ic, through the three-phase to two-phase transformation,
The alternating current of Ia1Ib1 is equivalent to a two phase stationary coordinate system, and then is rotated by the rotor field oriented,
Equivalent to the DC currrent Im1, It1 (Im1 equivalent to DC motor excitation current in synchronous rotating coordinate system;
It1 equal to the armature current proportional to the torque, and then imitate the DC motor control method, to obtain thee DC motor control,
The control of asynchronous motor is realized through the corresponding inverse coordinate transformation FR-ABR-H7 MITSUBISHI FR-ABR-H7 FR-ABR-H7.5K. 5K. 5K MITSUBISHI.
