    I figured you weren't allowed to share much,doesn't hurt to ask. I wont be seeing one those around here for years anyway.
    Out of curiosity, whats the drive bus voltage and how the volts/hz relationship plays out at high speed lets say 200hz? trying to compare it to a typical drive running on 460v with a 7.6 v/hz ratio, after 60hz the torque takes a steep dive.
