Hi, We use G120 with a 37kw PM for a water pump motor of 37kw. It gives F30002 when we raise the frequency from 30Hz to 47Hz by IOP hand mode. When we use a 45kw PM instead of the 37kw PM, the problem gone. The (DC link volt vs Time) graphs are attached. I want to keep using the 37kw PM by trying to rise DC link voltage threshold value (p2172). Would it cause any danger?

Hello I have replace master drives with the pm230 with a CU240 6SL32101NE232UG1 on a 15hp motor. I am seeing similar results. As the HZ increases the busvoltage is also increasing. It will trip on overvoltage at 60hz. I have a 30 hp drive that is doing the same thing but I have been able to keep it stable for now. I have never seen the bus voltage swing like this. The motor I am having the most trouble is free spinning not coupled to anything. The bus voltage will peak at 800 and then dip to 540. any thoughts? Thank you AttachmentF30002a.pdf (258 Downloads) |

Yes tried everything you have mentioned, it has a line reactor and it will run fine without reactor? why is the line reactor causing distortion/ noise on the dc bus.AttachmentF30002a.pdf (268 Downloads) |
