The drive output current (motor current) is what increases. Not sure if there is a choke on line side.
To give an update on this, I had the customer change the dynamic braking params because they were never setup. They said this seemed to prevent the drive from tripping but still get the current increase. They said they think there may be a mechanical problem that only shows itself at certain speeds. If I find out that it is a mechanical problem I will post that here so topic can be closed.
