MITSUBISHI inverter FR-A740 series.
Voltage level: 3 phase 400V.
Frequency converter capacity: 30KW.
FR-A700 converter products are suitable for all kinds of high load requirements of the equipment FR-A720-37K PDF.
Such as lifting, lift, printing and dyeing, printing and dyeing, material coiling and other general occasions.
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-A720-37K
With torque control mode,
And in the speed control mode can use the torque limit function FR-A720-37K PDF.
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.) and torque control. The built-in I/O function (Location: 1 axis) of the pulse output is converted to a differential drive output FR-A720-37K PDF. MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 0.75KW.
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 current Im1, It1 (Im1 equivalent to DC motor excitation current in synchronous rotating coordinate system;
It1 equal to the armatture current proportional to the torque, and then imitate the DC motor control method, to obtain the DC motor control,
The control of asynchronous motor is realized through the corresponding inverse coordinate transformation MITSUBISHI INSTRUCTION MANUAL MITSUBISHI INSTRUCTION MANUAL FR-A720-37K Manual. MITSUBISHI inverter series: FR-F840 MITSUBISHI INSTRUCTION MANUAL.
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 characteristic drrive motor FR-A720-37K INSTRUCTION MANUAL.
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-A720-37K Manual.
