Power: 0.4kw.
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-F840-04810-2-60.
The utilizattion 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 FR-F840-04810-2-60.
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-F840-04810-2-60.
The installation of thermal relay, to avoid overheating and burn the braking resistor. Can be isolated from the output of the programmable controller, the a/b/c contact relay, SSR, Tr output.
MITSUBISHI inverter series: FR-F840.

Power: 220kw.
SLD converter rated current: 481A.
Structure and function: Standard model.
Type: CA.

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 MITSUBISHI FR-F840-04810-2-60.
No need to adjust the parameters (plus deceleration time or torque, etc.), 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-F840-04810-2-60.
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).
Other manufacturers of induction motors, can also be automatically tuned to achieve the best excitation control, thus expanding the use of energy saving. Power: 55kw.
Voltage: 200V.
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 insstall the braking unit for each frequency converter, which can reduce the comprehensive space and reduce the comprehensive cost FR-F840-04810-2-60.
Renewable energy can be used for other frequency converter, excess energy back to the grid, to achieve energy saving.
