Toshiba DC Brushless Servos

Hello all,
I have acquired a manual for my Toshiba servo drives and have determined the following;
They require a Speed reference signal -10V to +10v analog signal which determines full speed CW to full speed CCW
Start command signal to enable them, aprox. 1 second after the main DC power, of 24VDC - 5mA
They output a dual quadrature pulse train 1024PPR A/A, B/B, and Z -1-PPR says, The pulse receiving circuit in the controller should use a RS422 differential line receiver, SN75173 (Texas Instruments) or AM26LS32C (TI or Advanced Micro Devices). The clock speed should be faster than 3 Mhz. The signal output voltage levels are 0 and 5 Vdc (nominal).
They also have a fault output transistor rated 5-24Vdc, 8-50mA.
Does anybody have any suggestions for a control. I have a Delta Tau that came with it, but it is more of a positioner control and doesn't have any interface for machine code, just loops and macros etc.
These drives will power 100 to 150 watt 3000RPM servos.
Thanks for any help.
