text: <s>[INST] Powerflex 525 Output voltage Lower than rating Summary: Powerflex 525 Output voltage Lower than ratingHello, regarding the specs of the powerflex 525, if the output Voltage specifications says :0..460V, 3 Phases, I am guessing I can use this to drive a 230VAC motor? I have an application where I have 480VAC and a 230VAC motor. There are PF525 with 120VAC 1 Phase input, 3 phase 230VAC output but that requires to upsize my 120VAC transformer. If I can just put the 230VAC motor on a 480VAC drive, my transformer will keep a reasonable size. Thanks! Antoine [/INST] I would recommend reading this technote: https://rockwellautomation.custhelp.com/app/answers/answer_view/a_id/516206/loc/en_US Luckily, it is an article listed for everyone. Short answer is that it is theoretically possible but you're most likely going to burn up the motor. The 230V motor most likely will have insulation rated for 230V, not 460V. A stepdown transformer and 230V VFD is the correct solution for that motor. Alternatively, get a 480V motor to eliminate the stepdown transformer. If you decide to try using the 230V motor on the 460V VFD, let us know how well it worked and how long the motor lasted before frying (if it did). I'm not being facetious - you might learn something that all of us could use. \\n </s>
