Need find info from servo motor HC-MF86 (Mitsubishi)

Hi
Please help in finding information about the servo amplifiers for servo motor HC-MF86 (800 watt 6000 rpm). In the datasheet there is no information about them, as there is no response from dealers mistubisi. These motors were actually released mistubisi. I need at least some toinformatsiya on servo for them. I thought fit MR-J2 100A, but it turned out that they only support the max HC-MF73 (700 watts 3000 RPM) .... Did anyone else dealt with them, I will be glad of any help.
