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 FR-A740-0.75K-CHT
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 constantt of the motor, the motor of other manufacturers, and the length of wiring is too long,
Optimum operating characteristic drive motor FR-A740-0 FR-A740-0.75K-CHT Manual. 75K-CHT PDF.
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) FR-A740-0.75K-CHT PDF.
Other manufacturers of induction motors, can also be automatically tuned to achieve the best excitation control, thus expanding the use of energy saving. MITSUBISHI inverter FR-A740 series MITSUBISHI PLC FUNCTION PROGRAMMING MANUAL.
Voltage level: 3 phase 400V.
Frequency converter capacity: 75KW.
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 PLC FUNCTION PROGRAMMING MANUAL.
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 adjustt 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,
Inveerter has a lot of protection functions, such as over current, over voltage, overload protection and so on MITSUBISHI PLC FUNCTION PROGRAMMING MANUAL FR-A740-0 FR-A740-0.75K-CHT PLC FUNCTION PROGRAMMING MANUAL. 75K-CHT Manual.
