I have a Otis 311 gem with ovf30 drive. Down with a cvt phase imbalance fault. All 3 legs are at 460 and within a few volts of each other. Wondering which board monitors this. Thanks

If you’re seeing any encoder pos faults with it you can try a new encoder but you likely need a new drive. It’s not a board swap fix. Otis is moving away from the ovf30’s with a magnatek Quattro upgrade.

If you need the drive rebuilt let me know
