Mitsubishi F840 series frequency converter fan and water pump load 11KW Mitsubishi frequency converter FR-F840-00250-2-60 3P AC400V; High-power inverter shall be equipped with reactor.

In addition to being used in many general occasions, F800 products are especially suitable for fan, water pump, air conditioning and other industries.

Mitsubishi F840 series frequency converter is applied to fan and water pump

Q: When will the F840 series frequency converter be selected?

A: F800 series frequency converters are generally used in light load industries, such as fans, water pumps and other industries. Because its applicable load curve is for variable-torque load, and the voltage is proportional to the frequency, we generally use it for variable-torque load by default.

Q: In the F840 model selection sample, what are the meanings of LD and SLD in the rated column?

A: LD: light load, SLD: ultra-light load.

Q: How should Mitsubishi frequency converter F840 be selected (One Belt One)?

A: Mitsubishi frequency converter selection mode is selected by referring to rated capacity and rated current. Generally, the selection condition of one frequency converter with one motor can meet that the rated current of the frequency converter is 1.1 times greater than the rated current of the motor.

Q: How should Mitsubishi frequency converter F840 be selected (more than one belt)?

A: Mitsubishi frequency converter selection mode is selected by referring to rated capacity and rated current. Generally, the selection condition of a frequency converter with multiple motors can meet that the rated current of the frequency converter is 1.1 times greater than the sum of the rated current of multiple motors. In case of sequential starting, an additional 6-8 times of rated current of * * * one motor shall be added.

Q: Can the F840 frequency converter carry motors with the same power? Example: 7.5kw frequency converter with 7.5kw motor.

A: Mitsubishi frequency converter selection mode is selected by referring to rated capacity and rated current. It may not be fully compatible under the same power. We also need to verify whether the rated current of the frequency converter meets the requirements. If the rated current of the motor X1.1 is greater than the rated current of the frequency converter, there may be an overload alarm during the operation process and it cannot work.

Q: Can the high-power F840 frequency converter be equipped with a low-power motor, and the power difference is large?

A: It is also inappropriate for high-power frequency converter with low-power motor. If the difference between power bands is too large, the output phase loss alarm (E.LF) will occur. The power difference is too large. If the protection parameters are not set properly, the motor will also burn. Therefore, the selection should be strict, and the frequency converter must match the motor.

Q: Can small power F840 frequency converter be equipped with large power motor?

A: Mitsubishi frequency converter selection mode is selected by referring to rated capacity and rated current. Generally speaking, the rated current of the small power converter will also be less than that of the large power motor, so this type selection is not feasible. The selection is still based on the rated current of the converter is 1.1 times greater than the rated current of the motor, combined with the power and current.
