wiring mesa 7i96s to servo driver as a spindle

Both are new to me, the 7i96s and the servo. The 7i96s is wired and running stepper motors, one of them closed loop stepper. Looks beautiful

My question:
In the past I used db25 bob with parallel port, and vfd spindle. The bob has 24 v Power supplied to it in order to supply a modulated analog signal to the vfd.

I read the 7i96s manual, I could not figure out where the outsource 20 vdc power supply is terminated into the 7i96s.

image for the servo driver is included for speed control mode

Good day

Drive needs 12-24V to enable, so you can use 12V supply for it and analog 0-10V, i would add two diodes in series from power supply to Mesa +10V pin to lover the voltage to 10.6-10.8V.
If you need both directions, adding a small relay with two pairs of contacts to reverse the input pins on the drive would work.

I realy appreciate your help

Which pin is the mesa 7i96s is the 10 vdc pin? is it on terminal block 2?

That is where I am stuck.

 

Yes, TB2, pin 24 named spindle+

OK

7i96s--servo drive

spindle- --->pin 13
spindle + -->pin 9 (12 vdc w/2diods in serial)
spindle out---->pin 25
