Toshiba DC Brushless Servo Drives

I have 3 Toshiba RA12 Brushless servo motors
1 Toshiba 170V DC power supply
and 3 Toshiba RA Drivers

My problem is this, I'm unable to find any manuals or support anywhere for these drives and don't know how I might find out how to hook this up.
There is a picture here.

I know the screw terminals are power in to the drive from the supply and power out to the motors.
The Blue 20 pin connector goes to the motor encoders.
The white 20 pin connector would go to the control and here is where I haven't any idea how to begin to sort out what pins would go to what and what type of control to use.
Any suggestions would be appreciated.
Thanks,
Brad Eyben
