text: <s>[INST] 2364F RGU Notch filter specification to meet IEEE-519 harmonic standard Hi all,is there anybidy who are familar with this issues?Because many customers need our common bus drive system to meet IEEE-519 harmonic standard,and I refer to manuals which shows that a notch filter will be needed at front of RGU .But I don't know the specification for each RGU.Many thanks to everybody here firstly. [/INST] I believe this is old product, I have not heard of a 2364. The current active front end is a 700AFE or a little older, but still available 1336R. The 1336 is for smaller applications and the 700AFE is for higher current. The sizing is done based on current requirements. I have only done this with single motor applications so the sizing is easy, for multi-drive applications the easy way is to get Rockwell drives managers to help out by giving them the motor sizes on the application. These do not require a notch filter on the input. The other option for IEEE-519 is a harmonic filter. TCI has one and MTe has one to meet IEEE-519. These would be typically be smaller applications as well where you will not have a lot of regen. \\n </s>
