MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 0.75KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%) FR-F720-3 FR-F720-3.7K7K TECHNICAL MANUAL.
Starting with power frequency power supply, the starting current is 6~7 times of the rated current, therefore, the impact on the mechanical and electrical.
The inverter drive can be smoothly start (start time longer).
The starting current is 1.2~1.5 times of the rated current, and the starting torque is 70%~120% rated torque;
For the inverter with the torque automatic enhancement function, the starting torque is more than 100%, which can start with full load FR-F720-3.7K TECHNICAL MANUAL. Max input / output points: 16 points.
Supply voltage: 100 - 240VAC.
Input points: 8 points.
Output points: 8 points.
Output type: relay.
Power consumption: 20W.
Weight (kg):0.6.
Size (WxHxD) mm:130x90x87 FR-F720-3.7K TECHNICAL MANUAL.
Since the FX2n series have the following features: the maximum range of inclusive of the standard features, program execution faster, the full complement of communication function, suitable for different countries in the world, and the power to meet a large number of special function modules of individual needs,
It can provide maximum flexibility and control capability for your factory automation applications.
Control 16~256 point.
Built in 8K capacity of the RAM memory, the maximum can be extended to 16K.
CPU arithmetic processing speed of 0.08 S/ basic instructions.
On the right side of the FX2N series can be connected to the input and output expansion modules and special function modules.
The basic unit is built in the 2 axis independent maximum 20kHz positioning function (transistor output type).
Quick disconnect the terminal block, which adopts excellent maintainability to quickly disconnect the terminal blocks, even if the cable is then replaced by the cable. MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 315kw.
SLD converter rated current: 683A.
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 drivve motor FR-F720-3.7K 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-F720-3.7K Manual .
