Viesturs, I suspect that your drive is monitoring the current being sent to the motor and "adjusting" things automatically and failing in that regard.
You may need a dumber V/Hz drive. Either that or turn off more "features" if that is possible via the drive parameters. I believe that the AC drives sold with the typical high freq Chinese spindle drives are very dumb.
