I recently installed a Reliance GV3000 AC Inverter on a machine. It took a few days to notice but when another similar machine (actually there may be 2 machines) with dc drives are running and you turn on this machine with the AC inverter they speed up. Voltage (240vac) stays constant but current increases by 1 amp on the incoming side of one of the dc drive machines. The AC line voltage is 240v, one dc drive is a Boston Gear Ratiotrol (the really noticeable machine that speeds up) and the other is a Reliance VS.
I have the line reactor in place on the incoming side of the AC inverter but it doesnt seem to make any difference.
I have been busy lately and I am not thinking straight on this. Any ideas on what I should be looking at? I may have to use an isolation transformer but with cost I am not sure thats practical.
Let me know what you think.
