text: <s>[INST] Powerflex 525 Test Bench Setup on single phase I am trying to make a test bench setup where I can control a 3phase 1/3HP motor from a single phase input. I currently have a 120VAC to 240V step up transformer that I have landed 240V single phase on L1/L2 of my 2HP PF525 model 25B0D4P0N114​. The HIM powers on but I have a F004 fault for low voltage that I cannot clear. I read 353VDC bus voltage when connected to the drive in CCW. I can connect to the drive in CCW but cannot modify any parameters. I read the tech note where Powerflex 25B series drives can take a single phase input and control a three phase drive de-rated but I have not been successful. Has anyone else been successful utilizing a single phase input? [/INST] That catalog number is 480V input and you are only providing 240V. Yes, you can bring in 1-ph and output derated 3-ph , but the input voltage must be correct. \\n </s>
