How to connect Rutex drive to Gettys DC servo controller?

I have Cincinnati Milacron milling machine which I've planned to
control by step & dir principle throughout e.g. Rutex R997 signal
converter (step & dir to +-10 V)

Original servo controllers in the machine are mady by Gettys, type 11-
1010-97.
unfortunately I don't have any diagrams for the machine.

Could somebody help me with the connections, e.g. where to connect +-
10 V from the Rutex?

In the Gettys, there are three terminal blocks in a row. Totally 17
terminals. They are marked as following describes:

TB 1
from 1 to 4 general mark AC LINE
Coil symbol between 1 and 3 also between 2 and 4
1 and 2 connected together with wire screwed to terminals, same
applies to 3 and 4

TB 2
5. +24 VDC
6. PWR GND
from 7 to 10 marked as SPARE
11. TACH FDB
12. TACH RESET RELAY
13. -EN

TB 3
14. D.B. RELAY
15. SIG.
16. SIG. GND
17. +EN

I could email the photos if somebody likes to see them.

Any help highly appreciated!

Cheers,
Juha
