Mitsubishi FR-D700 series frequency converter

Brand: Mitsubishi
Product name: 3-phase 400V frequency converter
Model: FR-D740-1.5K-CHT
Mitsubishi frequency converter FR-D740 series.
Voltage level: three-phase 400V.
Frequency converter capacity: 1.5KW.
The internal and rear structures of the frequency converter consider the cooling effect, and the relationship between the top and bottom is also important for ventilation,
Therefore, for the unit type inside the panel and hanging on the wall, it should be installed vertically as much as possible.
Can frequency converters be used to drive single-phase motors? Can single-phase power supply be used?
Basically, it cannot be used. For single-phase motor of speed governor switch start type, the auxiliary winding will be burned out when the speed regulation range is below the working point;
For capacitor starting or capacitor operation, it will induce capacitors.
The power supply of frequency converter is usually 3-phase, but for small capacity models, single-phase power supply can also be used.
Power: 55kw.
Voltage: 400V.
Braking resistor is a type of ripple resistor, mainly used in mechanical systems where frequency converters control motors to stop quickly,
Assist the motor in converting the regenerated electrical energy generated by rapid shutdown into thermal energy Mitsubishi FR-D740-1.5K-CHT.
Braking unit principle: The braking unit is composed of a high-power transistor GTR and its driving circuit.
Its function is to make DC part "overvoltage" when the discharge current link capacitor cannot be stored within the specified voltage range or the internal braking resistance cannot be consumed in time,
External braking components need to be added to accelerate the consumption of renewable energy FR-D740-1.5K-CHT power: 0.4kw.
Purpose: For power harmonics.
Improve power factor and reduce high-order harmonic current at the input end.
Ensure that the option is installed on Mitsubishi FR-D740-1.5K-CHT with capacities of FR-A820-03800 (75K) and above and FR-A840-02160 (75K) and above.
Install this option when using motors of 75kW and above. The IP55 series has a built-in DC reactor
Choose a DC reactor based on the motor power used.
When the capacity of the frequency converter is greater than that of the motor, the selection is still based on the motor capacity. The operation, monitoring, parameter modification, and other operations of the frequency converter can be carried out through a computer or PLC, Mitsubishi FR-D740-1.5K-CHT. Used to reduce radio noise. Applicable motor capacity: 1.5KW.
Rated current: 1.2A.
Power supply voltage: single-phase 200V.
The frequency converter is used in conjunction with GOT to achieve higher cost-effectiveness.
The GOT SIMPLE series can be directly connected to the IS70 series frequency converter.
GOT can be directly connected to the frequency converter. After connecting the two, the communication parameters can be automatically set for the Mitsubishi 3-phase 400V frequency converter.
In addition, the software component monitoring of sequential control function can be displayed in GOT, even when multiple frequency converters are connected,
One GOT can also be used for unified management.
After importing image data into GOT through GOT's image creation software,
Simply use RS-422 to connect the GOT to the frequency converter,
You can change the frequency converter speed/forward and reverse directions, monitor output frequency/output current, and set various parameters. Mitsubishi frequency converter series: FR-F840 Mitsubishi 3-phase 400V frequency converter.
Voltage level: three-phase 400V.
Power: 90kw.
Rated current of SLD frequency converter: 216A.
Structural functionality: Standard model.
Type: CA.
Substrate coating: Yes.
Without changing the motor efficiency during the previous optimal excitation control,
At the same time, the newly developed advanced excitation control can obtain a larger torque at startup from Mitsubishi 3-phase 400V frequency converter.
When accelerating to a certain speed in a short period of time, there is no need to adjust parameters (such as acceleration/deceleration time or torque increase),
Energy saving driving can be carried out to greatly improve the efficiency of the motor.
The Auto-Tune function for measuring the circuit constant of the motor is used when the motor constant is inconsistent, the motor of other manufacturers is used, and the wiring length is too long,
It can drive the motor FR-D740-1.5K-CHT with excellent operating characteristics.
In the sensorless state, it can not only drive Mitsubishi's energy-saving motors and PM motors (MM-EFS), but also drive other companies' induction motors and PM motors (permanent magnet synchronous motors) Mitsubishi FR-D740-1.5K-CHT.
Induction motors from other manufacturers can also achieve advanced excitation control through Auto-Tune, thus expanding the use of energy conservation.
