You mean a VFD for induction motors? No, they are not servo drives.
You need a servo drive.
First, you need to determine if these are permanent magnet motors.
Short two of the motor wires together, and see if the motor is very hard
to turn. If so, it is a permanent magnet motor. You will need a drive
that is compatible with that motor and the encoder system it uses. Not
all brushless motor encoder systems are standard, in fact most of them
are proprietary.
