I have a PP Rotary 7.5hp hooked to 5 machines, but only used one at a time. On an occasional basis it will fault out one of the VFD units. Incoming voltage is 240, output is 237, 243, 261. This is all No Load voltage, The 2 vfds are same model at set the same. The fault is overvoltage on one leg. Sometimes months go by without fault, then 5 times in a hour. Both VFDS have current reactors inline.
I blame the power company, but don't know. Any ideas to lower the voltage on that one leg?
