Connecting Mesa 7i76 to Sprint 1200 DC Controller was created by aharner
Good evening. I am not sure if this is the right area to ask this question, but here goes. I am converting a Novaturn lathe that has a Sprint 1200 (400) DC motor controller and I am using a Mesa 7i76U to handle the connections. I have the steppers moving properly, the e stop and limits working properly but am very apprehensive about connecting to the Sprint 1200 because I dont want to damage anything. Anyway, after days of reading, testing, and more reading I am finally reaching out for help. Does anyone know the correct wiring to connect the 7i76 (TB4) spindle connectors to the appropriate Sprint connectors? I need to be able to turn the motor on, adjust speed, etc. The motor does not reverse. The contacts on the Sprint are (1) +10, (2) MIN, (3) I/P, 4 COM, (5) RUN, (6) TACH, (7) COM. Any guidance would be appreciated.

Do you have some documentation on the Sprint 1200 connections?
Just knowing the names is not enough to know how to connect them.

Yes I do. I have the right hand side of the Sprint all taken care of, its the low voltage/control side that I cant figure out. Thanks in advance for your help.

So
7I76EU TB4 DRIVE
1 SPINDLE- 2 MIN
2 SPINOUT 3 IP
3 SPINDLE+ 1 +10V
5 ENA- 4 COM
6 ENA+ 5 RUN
Note that some or all of these connections may be at line potential
so make sure you do not touch them or allow them to connect to
any low voltage signal.

Sir, thank you for your immediate response, I had the first two pins figured out but the last ones I needed clarification. Time to get her spinning. Can't thank you enough.
