text: <s>[INST] 400v Powerfelx 700A AC drives with 480V input and 460V motors Summary: Hi, We built a machine for 380V usage, now we have to use it in US with 480V. Hi All, We built a machine for 380V usage. Now we are forced to use it in states 480V. I know that there is a voltage setting in powerflex drives (High / Low Voltage). So My question is by selecting the high voltage option is it possible to use the same drive with 480V Input. If, Yes then I don't understand why there is a separate catalog numbers for 400 & 480V drive in powerflex. [/INST] Yes, there is a high/low voltage parameter permitting operation at 400V or 480V. There are different catalog numbers so that if you purchase a drive suitable for your geographical location, the drive defaults to the proper voltage. This makes it somewhat more attractive to purchase a Rockwell drive in Europe and other locations with 400V power without having to worry about getting that particular setting correct. If Rockwell defaulted to 480V power, they wouldn't sell as many outside the USA. \\n </s>
