Scientific selection of frequency converter is crucial to the normal operation of frequency conversion system. A lot of beginners to the general inverter selection method understanding is not enough, or even if you know the method, but also not sure whether the choice of the inverter model is the right solution, the following small an for everyone to solve the mystery.

Firstly, the selection of frequency converter should meet the needs of field conditions. If the site requires a single machine to achieve 680KW, we will choose AMB300 series inverter; If the field requires closed loop vector control, it is necessary to choose AMB600 series inverter; If the field only requires 1 analog output, 1 relay output, you can consider the AMB100 series inverter.

All frequency converter manufacturers boast that their products cost - effective, the common reason, the old woman said the old woman is right. However, xiao an suggested that the type selection of inverter can be domestic to change the need not imported, can be used general need not special, can use small power need not large power, simple is to save money.

Converter selection must consider the after-sales service, because converter maintenance is a small matter, affect the production schedule is a big matter. Most users think that the quality of foreign brand inverter is more stable than that of domestic brand inverter. In fact, after 2010, domestic inverter technology has achieved a fundamental technological breakthrough.

The selection of frequency converter is mainly determined by the load characteristics of the drive and the actual working current of the motor. In addition, there are the following considerations:

The selection of frequency converter is a technical work, if the selection is not appropriate, the frequency converter may be damaged, serious will affect the normal production of the factory, so scientific and reasonable selection of frequency converter is crucial. The following list of inverter modeling principles for end-users reference.

Rapid shutter door is through the rapid shutter door frequency converter and drop, shorten the material and the pedestrian's entrance and exit time and design of automation equipment, in foreign factories have been popular, and the domestic rapid shutter door industry started late, all aspects of technology and supporting is not very perfect. In order to improve the quality of products and ensure the safety of the factory, rapid rolling door production and application will be an inevitable trend.
