4, when the frequency converter is used to control several motors in parallel, it is necessary to consider the total length of the cable from the frequency converter to the motor within the allowable range of the frequency converter.
5, for some special applications, such as high ambient temperature, high switching frequency, high altitude, etc., this will cause the reduction of the frequency converter, and the frequency converter needs to be amplified for selection.
6, when choosing a frequency converter for high-speed motors, it should be slightly larger than the frequency converter for ordinary motors.
7. When the frequency converter is used for the variable pole motor, full attention should be paid to the selection of the capacity of the frequency converter so that its maximum rated current is below the rated output current of the frequency converter.
8. When driving explosion-proof motors, the frequency converter has no explosion-proof structure, and the frequency converter should be set outside the dangerous place.
9. When the frequency converter is used to drive the gear reduction motor, the scope of use is restricted by the lubrication method of the gear rotating part. Do not exceed the maximum permissible speed.
