MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 30KW.
When the ring is opened, the frequency converter is provided with a load of the motor when the motor is operated with a load at a given frequency,
The range of the motor speed in the rated slip ratio (1%~5%) changes.
For the requirements of relatively high precision, even if the load changes are also required to operate at a given speed of the occasion,
Inverter with PG feedback function can be used (selection).
If the given acceleration time is too short, the output frequency of the inverter is far more than the change of the speed (electric angular frequency),
Converter will be due to flow over the current trip, the operation stopped, which is called stall.
MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 15KW.
FR-A700 converter products are suitable for all kinds of high load requirements of the equipment.
Such as lifting, lift, printing and dyeing, printing and dyeing, material coiling and other general occasions MITSUBISHI FR-F720-30K.
High level driving performance.
Unique sensorless vector control mode,
A wide variety of mechanical equipment can be operated at high precision in the super low speed region without the need of the encoder
FR-F720-30K
With torque control mode,
And in the speed control mode can use the torque limit function.
With vector control function (with encoder),
Frequency converter can achieve position control and fast response, high precision speed control (zero speed control, servo lock, etc MITSUBISHI FR-F720-30K. ) and torque control. MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 55KW.
Frequency converter is the application of frequency conversion technology and micro electronics technology, by changing the motor operating power frequency mode to control the AC motor power control equipment MITSUBISHI FR-F720-30K.
The converter is composed of rectifier (AC), filter, inverter (DC), braking unit, driving unit, micro processing unit of the detection unit.
Inverter by the internal IGBT to adjust the output power supply voltage and frequency,
According to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition to the,
Inverter has a lot of protection functions, such as over current, over voltage, overload protection and so on. MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 37kw.
SLD converter rated current: 77A.
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.), 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 characteriistic drive motor FR-F720-30K.
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).
Othher manufacturers of induction motors, can also be automatically tuned to achieve the best excitation control, thus expanding the use of energy saving FR-F720-30K.
