OK, sounds like was over current originally so P076 could go up again but I wouldn't load it too long like this. I don't know what else to suggest as I don't want to damage your motor. The old motors were not so inverter friendly so you could try running it at 60 Hz (3450 rpm) unless it is a newer motor designed for inverters.

Just check the parameters are OK and look inside the motor connection box to confirm how it is wired (unplug first !)
