Power: 7.5kw.
Voltage: 400V.
Purpose: high frequency braking resistor.
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.

Superior high efficiency IPM motor.
Output power: 7.5kw.

Voltage level: 200V.
IPM motor MM-EFS series can not be used to run the power frequency power.
The total wiring length of the IPM motor shall not exceed 100m.
1 inverters can not connect multiple IPM motors at the same time MITSUBISHI FR-BU2-H7.5K. MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 90kw FR-BU2-H7.5K
SLD converter rated current: 216A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
The motor efficiency is not changed in the previous optimal excitation control,
At the same time, the newly developed advanced optimal excitation control can obtain larger torque at startup.
No need to adjust the parameters (plus deceleration time or torque, etc MITSUBISHI FR-BU2-H7.5K. ), in a short time to speed up to a certain speed,
Can be carried out to maximize the efficiency of energy-saving drive motor.
The automatic tuning function of the loop constant of the motor is not consistent with the constant of the motor, the motor of other manufacturers, and the length of wiring is too long,
Optimum operating characteristic drive motor MITSUBISHI FR-BU2-H7.5K.
In the state of the sensor can not only drive the high efficiency and energy saving motor and PM motor (MM-EFS), but also can drive other companies induction motor and PM motor (permanent magnet synchronous motor) MITSUBISHI DC reactor.
Other manufacturers of induction motors, can also be automatically tuned to achieve the best excitation control, thus expanding the use of energy saving MITSUBISHI DC reactor. Superior high efficiency IPM motor.
Output power: 55kw.
Rated speed: 1500r/min.
Voltage level: 200V.
IPM motor MM-EFS series can not be used to run the power frequency power.
The total wiring length of the IPM motor shall not exceed 100m.
1 inverters can not connect multiple IPM motors at the same time MITSUBISHI DC reactor. Power: 5.5kw.
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 rreach 300 degrees C or higher, it is necessary to take protective measures and cooling FR-BU2-H7.5K.
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-H7.5K.
The installation of thermal relay, to avoid overheating and burn the braking resistor.
